Overview and requirements
Overview
AudioSpectrum is audio viewer and processor, which work in web
browser. It consists of the following modules:
- Spectrogram - display sound spectrogram.
- Stereo scope - display side-mid or
left-right in X-Y mode.
- Filter - create finited-impulse-response
brick-wall frequency filter.
- Process control - set filter processing
including brick-wall filter, adding noise and volume
control and place frequency markers.
- Playlist - play audio from file instead
of live audio recording.
Example AudioSpectrum pusposes:
- Display audio spectrogram.
- Check if audio is stereophonic or monaural.
- Check stereo balance.
- Redirect audio from recording device to playing device.
- Apply lowpass/highpass/bandass filter.
- Change stereo base size.
Requirement and compatibility
AudioSpectrum requires a web browser compatible with HTML5
WebAudio and LocalStorage, so it is compatible with current
version of Mozilla Firefox and Google Chrome for Windows and for
Android. This application will probably work with other PC and
mobile web browsers, but working in browsers other than mentioned
is not tested and not guaranteed.
Settings screen
The settings screen can be achieved by clicking on the graphic
screen in Spectrogram, Stereo scope
and Filter modules or by clicking the Settings
button in the remaining modules.
This screen, on the top and bottom contains the followin
buttons:
- Close - Close settings screen.
- Pause - Pause and resume drawing on
spectrogram and stereo scope, the audio will be processed
in background.
- Fullscreen - Switch the web browser to
fullscreen mode.
- Start/Stop - Start and stop audio
capturing and processing.
All number values are integer values. Some parameters has
value with fraction part, even can have only fraction value (for
example value from 0.000 do 1.000).
Such parameters are indicated as x1000, which
means, that value in the field is a result of multiplication of
1000 and real value.
Module layout settings
Application modules are enumerated from 0 to 5. The module
layout can be changed in LAYOUT section. The Module
(0-5) order field provides visibility and order
configuration. The inputted numbers representes modules, which
are visible. The numer order determines module display order. The
other characters than digits from 0 to 5
are ignored, also the second and further instances of the same
number are ignored.
Every module width matches screen wide, but the height can be
drfined either by percent of screen height or by size in pixels.
Each module has two fields to define size. The first field is the
size value, the second field is the size unit (pixels or
percent).
General settings
The informations and settings in GENERAL
section are not related to specified module and will affect all
application working.
The information values are:
- Input sample rate - Audio input sample
rate, it depends on web browser implementation..
- Output sample rate - Audio output sample
rate, it depends on web browser implementation..
- Screen resolution - Whole browser screen
size, including toolbar, margins, etc.
This section also contains the following settings:
- Drawing gamma x1000 - Gamma values used
to spectrogram and stereo scope level display.
- Spectrum window type - Window type used
to calculate Fourier transform used in spectrum.
- Audio buffer size [samples] - Audio
recording buffer size, it must be choosen experimentally.
- Audio echo cancellation - Echo
cancellation using WebAudio parameter (may not work in
some web browsers).
- Audio noise suppression - Noise
suppression using WebAudio parameter (may not work in
some web browsers).
- Audio auto gain control - Auto gain
control using WebAudio parameter (may not work in some
web browsers).
- Auto start - Auto audio start directly
after application loaded. The Enabled
option may not work in some web browsers. The Screen
option causes, that the first click on screen will start
audio instead of action assigned to clicked object. This
option is usable when Enabled does not
work.
- Auto fullscreen - Auto switching to
fullscreen mode, work the same way as Auto start.
- Button font size [points] - Button font
size in Spectrogram, Stereo
scope and Filter modules.
- Color picker - Enable or disable color
picker in setting fields, which are color parameter. In
some web browsers, which supports color-type fields,
color choosing is limited and there is not possible to
input arbitrary color channel values. When disabled,
instead of color button there will be displayed text
field and color value is represented in #RRGGBB
pattern, where RR, GG, and BB are hexadecimal channel
values.
Some settings, either general settings, or settings related
with any module, requires restart autio capture (by Start/Stop
click) or restart application (by page refresh).

any of these button, you have to restart AudioSpectrum by page
refresh to take effect.
Spectrogram
Purpose
This module shows audio spectrogram (spectrum in time). It can
be used to visualize many sounds, also it shows audio balance
using colors. This module can also be used to check, if input
device is ocerloaded or check audio frequency characteristics.
Functions in main toolbar
Spectrogram has following parameters, which value can be
changed using the following buttons in toolbar:
- Gain (G-, G+) - Sound gain, it should be
set according to input sound volume to get signals enough
perceptible (not too dark and not too bright).
- Resolution (R-, R+) - Frequency spectrum
resolution, lower frequency resolution will result in
higher time resolution, lower performance requirement and
vice versa.
- Window (W-, W+) - Part of window used to
calculate spectrum without changing resolution, changing
result is similar to changing resolution, but spectrum
will be smoother and this setting not affects in
performance requirement.
- Zoom (Z-, Z+) - Vertical spectrum size.
- Offset (O-, O+) - Vertical spectrum
position.
- Step (S-, S+) - Number of samples per
one pixel, the lower step will result in higher speed in
drawing, so the more details will be perceptible.
- Base (B-, B+) - Brightness of zero
value, used to highlight weak signals or hide uniform
noise without gain changing.
- Min/Max (M-, M+) - Number of values used
to display minimum (negative) or maximum (positive)
value, it can highlight weak signals in some cases.
- Lines (L-, L+) - Number of lines
(tracks) displayed once.
On the both buttons in evry pair above, the number represents
the current parameter value. The toolbar has also the following
functions:
- Disp - Switch between spectrum and
waveform or switch between display modes. There are nine
possible states, each state is the pair of:
- View mode - The way, in which
graph is displayed:
- Normal - Draw
sequentially from left to right.
- Half - Draw additional
line moved by half of screen width.
- Scroll - Scroll
spectrogram from right to left, draw at
the right side.
- Graph type - The graph type,
which is generated and displayed:
- Spec - Spectrogram.
- Wave - Audio waveform.
- Vol - Volume unit as
rectified waveform.
- Pause - Pause or resume spectrum drawing
without turning off audio input, if audio input is not
turned on, it will be turned on.
Functions on logarithm toolbar
In spectrogram settings, you can enable additional toolbar,
which allows to enable and adjust logarithmic display. The
buttons has the following functions:
- Mode - Switch between two states of
logarithm toolbar. This function does not affect the
display, but determines the value type, which will be
affected, when you click the other buttons.
- Freq - Use toolbar to set the
frequency scale settings.
- Ampl - Use toolbar to set the
amplitude scale settings.
- Scale - Switch between linear and
logarithic scale of frequency or amplitude. This function
affects spectrogram only. The waveform or volume display
will not be changed.
- Line - The linear scale. The Base,
Factor and Offset
parameters will not affect the scale.
- Log - The logarithmic scale. Use the the Base,
Factor and Offset
parameters to adjust the scale.
- Base (B-, B+) - Base of logarithm.
- Factor (F-, F+) - The factor of
logarithm value result.
- Offset (O-, O+) - The logarithm value
offset.
- Step (S-, S+) - Step of base, factor and
offset change at once button click.
If the scale for frequency or amplitude is set to logarithmic,
the buttons on the main toolbar will have the same effect. The
logarithmic scale means only changing frequency or amplitude
values using logarithmic function and for this reason, you have
to adjust the logarithmic display using Base, Factor
and Offset parameters. You can disable logarithm
toolbar after setting the logarithmic scale.
Waveform display
Using Disp button, you can display waveform
to check, if audio device is correctly drived, so if audio signal
is present, not too low and not clipped. In waveform mode,
display controls other than Resolution,
Window and Min/Max works in the same
way, as in spectrum mode. The Resolution and Window
control not affects in waveform display. The Min/Max
changes number of steps to display maximum value to get maximum
sample values more perceptible The negative and positive value
will give the same result, the 0 value is
treated as 1 in waveform mode.
Settings
The informations and settings related to spectrogram module
are in the SPECTROGRAM section:
- Canvas resolution - Real spectrogram
canvas resolution after pixel scaling.
- Decimated sample rate - Spectrogram
audio sample rate after decimation.
- Sample decimation - Samplerate divider
to get lower audio sample, which requires lower
performance, the value of input samples are averaged.
- Spectrum window type - Window type used
to calculate Fourier transform used in spectrum.
- Canvas orientation - Whole canvas
clockwise rotation with flipping or without flipping,
usable especially on some mobile devices with locked
screen automatic rotation. The flipping means swapping
graphics drawing axes.
- Spectrum band flip - Spectrogram band
flipping to change frequency and offset increasing
direction.
- Logarithm quality - The quality of
drawing when frequency scale is in logarithm mode, this
slightly affects the requirement performance. There are
three modes:
- Low - No interpolation across
full frequency scale.
- Medium - Interpolation in higher
frequencies, where one display pixel is assigned
to several calculated pixels.
- High - Interpolation across full
frequency scale. This mode is recommended.
- Toolbar position - Visibility and
position of toolbar on module area. It is possible to
display in 2-row or 4-row layout.
- Logarithm toolbar - Display the
logarithm toolbar next to the spectrogram main toolbar.
This toolbar is necessary to change display scale and
adjust logarithmic scale display.
- Toolbar size [%] - Tool bar size as
module size percentage.
- Decimate below step - Minimal step
value, when spectrum is calculated for every step. If
step size is less than this value, the spectrum will be
repeated, so performance requirement will be lower, but
spectrum time detail display will be slightly lower. This
value is usable in displaying lower spectrum steps with
fast drawing, when the lower spectrum steps than this
value will require only slighty higher performance.
- Decimate above resolution - Maximum
resolution value, when spectrum is calculated for every
step. If resolution is greater than this value, the
spectrum will be repeated, so performance requirement
will be lower, but spectrum time detail display will be
slightly lower. This value is usable in displaying higher
spectrum resolutions with fast drawing, when the higher
spectrum resolutions than this value will require only
slighty higher performance.
- Scroll decimate below step - Decimate
below this step, within the scrolling display mode, when
the decimation determined by Decimate below step
and Decimate above resolution are less
than decimation determined by Scroll decimate
below step. The scrolling requires significantly
more performance than normal or half line mode.
- Canvas width scale - Scale canvas pixel
width, usable if screen pixels are very small and may
decrease performance requirement.
- Canvas height scale - Scale canvas pixel
height, usable if screen pixels are very small and may
decrease performance requirement
- Pointer strip size - Pointer strip width
in pixels.
- Pointer strip color - Pointer strip
color value.
- Input overdrive threshold x1000 -
Absolute 16-bit sample value, wher audio input overdrive
will be indicated. Some overdriven audio devices
generates sample absolute values slighty lower than
1.0/-1.0, so the value must be slightly lower than
maximum absolute sample value. To turn off overdrive
indicator, set this value above 1000, which means 1.0.
- Output overdrive threshold x1000 -
Absolute 16-bit sample value, wher audio output overdrive
will be indicated. Incorrectly set audio processing can
generate sample values higher than maximum, this will
make output audio distortion. To turn off overdrive
indicator, set this value above 1000, which means 1.0.
- Overdrive color - Overdrive indicator
color.
- Overdrive opacity - Overdrive indicator
opacity from 0 to 255, if value is 0, the indicator will
not be visible, if value is 255, the indicator will be
opaque.
- Waveform background level - Simulated
spectrogram level for background in waveform mode from 0
to 65535.
- Waveform foreground level - Simulated
spectrogram level for foreground in waveform mode from 0
to 65535.
- Repaint length [samples] - Number of
samples, which can be repainted backward in every action,
which affects spectrogram/waveform display. This value
affects the range of repainting backward.
- Repaint step [pixels] - Number of audio
steps (pixels), which will be repainted by one current
audio step. It value must be choosen experimentally, the
higher value will result by faster repainting, but
requires higher performance.
- Audio channel R - Audio channel
assignment to red color channel.
- Audio channel G - Audio channel
assignment to green color channel.
- Audio channel B - Audio channel
assignment to blue color channel.
- Audio gain R x1000 - Red color channel
value gain, usable to change color tint. This value may
not to be confused with spectrum gain.
- Audio gain G x1000 - Green color channel
value gain, usable to change color tint. This value may
not to be confused with spectrum gain.
- Audio gain B x1000 - Blue color channel
value gain, usable to change color tint. This value may
not to be confused with spectrum gain.
- Marker size - Frequency marker line
width on spectrogram. This actual marker line width will
be rounded to nearest multiply of frequency pixel size.
Stereo scope
Purpose
This module displays sound as X-Y scope. It can display input
audio or output audio or combined both streams simirally like
analog oscilloscope. The axis can be treated as audio channels
(left and right) to display for example Lissajous curves or
"vector graphics" designed to display on oscilloscope
connected to audio output device. Insteat of Left/Right axis,
there can be displayed Side/Mid axis to better show, if audio is
monaural/stereophonic, stereo base or stereo balance. The input
device overloading can be shown by display signal very close to
canvas edge, while edge represents the maximum audio value, while
the gain for X and Y is set to 1.
Functions in toolbar
The Stereo scope module has toolbar, in where there are
buttons, which changes display parameters, the value will be
changed by Step value, the buttons are in pais:
- X-, X+, Y-, Y+, Z-, Z+ - Sound gain
across X/Y/Z axis.
- Dim-, Dim+ - Display dimming factor, the
canvas dims by multiplying every pixel value by dimming
factor, until pixel value is blow 0.001, when is visible
as black.
- Pxl-, Pxl+ - Chabge pixel drawing radio.
When 0.000, there will be drew lines
between value points only, when 1.000,
there will be drew pixels, which represents sample value.
The other values means proportionally combining the both
approaches.
- Step-, Step+ - Change value change for
above parameters.
The other buttons are toggles between display modes and can
have one of several captions, which represents the current state:
- SM/LR - Switch between Side-Mid or
Left-Right display mode.

Filter
Purpose
AudioSpectrum has a ability to record and play processed audio
in real time. Within processing, there can be user up to 4
brick-wall filters. Each filter is a finited-impulse-response
filter, which windows size and windowing function can be defined
and affects the required performance, audio latency and filtering
accuracy. Each filter is defined by frequency characteristics and
can act as for example lowpass filter, highpass filter or
parametric equalizer.
Abilities and visualization
AudioSpectrum can store 4 filter definitions in 4 slots with
independed properties. The frequency axis may be divided into
segment with independed values, while positive value means
amplifying and negative value means damping signal across
specified frequencies. On the graph there is displayed 0 value as
horizontal line across whole frequency range. The frequency range
is from 0 to half value of input sample rate. There also draew
theoretical response, which is defined be user and practical
response, which is computed as FFT of generated filter serie,
including windowing function and window size.
Functions in toobar
The toolbar has the following buttons, which has constant
function:
- Slot 0, Slot 1, Slot
2, Slot 3 - Choode filter slot.
- Step-, Step+ - Chage filter frequency
and value step, this also affects to value step in Process
control module.
- <<, >> - Select frequency
band, the selected band will be show as thick level line,
is is possible to select none of bands.
The buttons available, when any band is selected:
- Add - Add ne wband by splitting selected
band into two parts.
- Rem - Remove selected band.
- Level-, Level+ - Change band level.
- |<, |> - Change band lower
frequency.
- <|, >| - Change band upper
frequency.
The buttons available, when none of band is selected:
- None/Hamming/Blackman - Windowing
formula.
- Win-, Win+ - Length of filtering window.
- [+], [-] - Zoom in or zoom out filter
view
- [<<], [>>] - Move viewed
part of filter, whet it is zoomed.
Changing the position value unit
The default unit used in the filter band position is the
number of elementary units. You can change this unit to sound
frequency and from sound frequency. To do this, click the <<
or >> several times (not to be confused
with [<<] or [>>])
to reach the state, when no band is selected and press the same
button one more time to select the opposite band. The filter
working will not be changed. The value using the selected unit is
displayed on the |<, |>, <|
and >| buttons (change band frequency).
Settings
The settings related to Filter module are in the FILTER
section:
- Filter canvas resolution - The filter
canvas current resolution
- Process filtering - Toggle audio
processing, when Disabled, the inpus stream will be
redirected to output without touching.
- Toolbar position - Filter toolbar
positin.
- Toolbar size [%] - Filter toolbar size.
- Filter min level [dB] - Minimum possible
and visible filter level value.
- Filter max level [dB] - Maximum possible
and visible filter level value.

displays 0dB level.
- Spectrum color - Color of computed
filter frequency response.
- Level line color - Color of level line,
which represent ideal frequency response and indicates
input filter levels.
- Marker size - Frequency marker line
width on filter graph.
The settings related to autio playback and processing are in
the PLAYBACK section:
- Play output audio - Generate and play
output audio (directly or processed). If AudioSpectrun is
used to visualize input audio, this settings should be
set into No.
- Min play buffer [ms] - Minumum playback
buffer time.
- Max play buffer [ms] - Maximum playback
buffer time.
- Soft margin [ms] - The margin from
min/max bound, where player starts periodically adding or
removing one sample per period.
- Sample add/remove period - Number of
samples, per which player adds or removes one sample,
when real playback buffer reaches soft margin.
- Draw buffer on spectrogram - Diagnostic
function, draws buffer indicator over spectrogram canvas,
where the lower display edge represents the minimum time
and the upper display edge represents the maximum time.
The spectrogram display zoom and offset does not matter.
This function can visualize buffer time fluctuation
during playback.
- Buffer background shade - The shade of
gray to draw soft min/max bounds and middle playback
buffer lines.
- Buffer foreground shade - The shade of
gray to draw hard min/max bounds lines and real playback
buffer time.
- Mute audio playback - Mute audio
playback (the sample values will be changed to zero
directly before play) while playing live (recording)
audio or audio from playlist or in both cases. There are
the following modes:
- None - No mute audio.
- Live - Mute live audio only, the
audio from playlist will be generated.
- Playlist - Mute audio playback
from playlist, the live audio will be generated.
- All - Mute both live audio and
playback from playlist.
The playback timing can slighty differ from recording timing,
also due to perfomance-demanding activities. The playback buffer
is the time between aquire audio data pack to play and placing
the data in play timeline, so the times fluctuates during play.
This is very visible when drafing buffer on spectrogram is
enabled and allow to test buffer parameters. The Min play
buffer and Max play buffer defines the
hard play buffer bounds. When player is initialized, the first
playback buffer time equals to average time between hard bounds
and there is a middle time. The Soft margin
defines the soft buffer bounds. The lower soft bound is the lover
hard bound increased by soft margin, and the upper soft bound is
the upper hard bound decreased by soft margin.
During playing, there are possible the following scenarios:
- When playback buffer time reaches beyond lower soft
bound, for next audio chunks there will be added one
sample (copied from previos sample) per certain period
(the sound pitch may me slighty decreased), until the
playback time will be upper than middle time.
- When playback buffer time reaches beyond upper soft
bound, for next audio chunks there will be remover one
sample per certain period (the sound pitch may me slighty
increased), until the playback time will be lower than
middle time.
- When playback buffer time reaches beyond lower or upper
hard bound, the playback buffer time for next audio chunk
will be changed to middle time and small distortion will
be audible.
Process control
Puspose and abilities
This module provides the audio processing configuration by
series of process transforms. There are available the following
transforms:
- Null - No transform.
- Filter - Apply brick-wall filter, you
can choose one of four filters for every audio channel,
but is is recommended to define for left and right
channel or for mid and side channel only. Otherwise,
there are applied two filter processes, the first is
filter for left and right channels, and the second
process is filtering the mid and side channel. The ~
sign indicates no filter processing for this channel.
- Volume - Change audio volume, balance,
stereo base etc.
- Noise - Add dual-channel white noise to
audio. The volume of original audio will be not changed.
- Invert L - Invert left channel phase.
- Invert R - Invert right channel phase.
- Swap stereo - Swap left and right
channels.
The other purpose of this module is setting frequency markers
to display.
Creating transform list
To add transform, you have to click Add before first
or Add after last button. The Settings
button brings screen of settings, the Step- and Step+
changes gain value change step. The transform is shown in table.
In the Transform column there are three buttons.
The first of them removes the transform and the other buttons
moves transform up or down across the table to change transform
order. The drop-down list allows to choose transform operation.
In the columns Left, Right, Mid
and Side, you can choose filter slot or change
gain for this channel. Sobe transforms has no parameters to
change.
Saving and loading transform configurations
Below the transform table, there are buttons, which allows to
save and load whole process configuration, including filter slots
into 10 slots from 0 to 9. This buttons are the following
function:
- Save X - Save process configuration into
X slot.
- Load X - Load configuration from X slot.
- Clear X - Clear X slot.
Frequency markers
In the Process control module, you can also
set up to 10 frequency markers, which will be displayed on the
spectrogram and on the filter graph. To display marker, check the
checkbox in the Marker column, next to the
number from 0 to 9. In the Color column, you can
define the marker color. The Value column
determines the place of the marker within filter and spectrogram
frequency range. The value is in one of the following units,
which can be choosen in the Unit column:
- Hz - The sound frequency value in Hertz,
to set the specified sound frequency.
- /10000 - The 1 of 10000 parts, to set
the placement as fraction of the whole band.
- /8192 - The 1 of 8192 parts, to set the
placement as fraction of the whole band, the unit can
help to place the marker accurately on the spectrogram by
frequency pixels.
Spectrogram strip coloring section
This section in Process control module allows
to put frequency marks on spetrogram strip. The marks are the
areas and can be periodical. The strip coloring is defined by
text. Each valid text line carries the information about strip
coloring. The invalid lines are ignored.
When you apply the text, it will be filtered as follows:
- Split text into lines.
- Remove all character other than space, numbers, point,
comma, arithmetic symbols (add, subtract, multiply,
divide).
- Replace all commas to points, which allows use comma as
decimal separator instead of point.
- Remove leading and trailing spaces.
- Replace multiplied spaces to single space.
- Split text line into array by spaces.
There are two valid kinds of text lines:
- Base - Defines the base frequency and
amount of periods, consists of five elements:
- Base frequency - the frequency,
from which the markers will be calculated.
- Addition or multiplication - The
+ or *
character, which means, if the base frequency
will be calculated by addition or multiplication.
- Difference or factor between two
frequencies:
- If addition: The difference from dwo
frequencies.
- If multiplication: The factor, by which
the base frequency will be multiplied or
divided.
- Lower limit - The lower limit of
base frequency change to repeat the markers, 0
means the base frequency.
- Upper limit - The upper limit of
base frequency change to repeat the markers, 0
means the base frequency.
- Marker - Defines one marker period and
color, consists of seven elements:
- Operation for lower limit -
Allowed characters are +, -,
*, /.
- Value for lower limit - The
value, which will be added, subtracted,
miltiplied or divided do base frequency or repeat
equivalent.
- Operation for upper limit -
Allowed characters are +, -,
*, /.
- Value for upper limit - The
value, which will be added, subtracted,
miltiplied or divided do base frequency or repeat
equivalent.
- Red color value - Value from 0
do 255.
- Green color value - Value from 0
do 255.
- Blue color value - Value from 0
do 255.
Spectrogram strip coloring examples

There is base frequency 440Hz, which determines the A tone
frequency. The 12 markers defines one octave and are in the
following order: C#, D#, F#, G#, A#, C, D, E, F, G, A, B.
Totally, there are 11 octaves, 5 octaves below base and 5 octaves
above base. To be more visible, the C, D, E tones have darker
shadow than remaining whole tones.

Octaves and thirds
There are standard division acoustic into octaves, each octave
is individually divided to three thirds. The base frequency is
1000Hz and from this frequency there are 6 octaves in light gray
and there is second base 2000Hz to mark the remaining 5 octaves
in dark gray.

Playlist
Purpose
Instead of live input audio, AudioSpectrum has ability to play
sound files from playlist. In fact, while playing sound from
playlist, application also records sound from input device, but
recorded sample values are substituted by samples from loaded
sound file. This feature may be used to process audio from music
file without using external player or to "display"
sound designed to display on X-Y oscilloscope, in such case,
there will be processed samples directly from file, without
passing through audio devices.
Creating and managing
The playlist module provides the Settings
button, which prings the Settings screen and drop-down list,
which provides two options:
- Live audio - Audio from input device, in
this mode the playlist is not used and playing is frozen.
- Audio from playlist - Play audio from
playlist, played audio will be treated as recorded input
audio.
To add files, you have to select file into field Add
audio files. The recognized files will be added to
playlist table and stored in internal memory. You can add several
files once. In the table there are the following columns:
- Operations - Buttons related to item,
from left to right, there are Remove, Move
up and Move down.
- Index - Index number.
- File name - Original file name.
- Sample rate - Sample rate read from
file.
- Channels - Mono or stereo indicator.
- Length - File length in samples.
To manage playing files from playlist, you can use the buttons
above playlist table:
- |< - Previous item
- << - Increase backward play speed
or decrease forward playing speed.
- < - Play backward at base speed
- [] - Stop playing
- > - Play forward at base speed
- >> - Increase forward play speed
or decrease backward playing speed.
- >| - Next item
The playing base speed will be accord to recording sample
rate, not to file sample rate. The playlist storing is not
possible because JavaScript API does not provide automatically
loading files basen on the file path and name.


Flexible working hours
Team members are free to choose the hours that work best for them, within 7am-7pm on weekdays. To ensure there is ample overlapping time for teammates to work together, the hours you choose should include the hours of 10am-4pm (with the exception of a reasonable lunch break).
The hours you work can change day-by-day, and you don’t need to let anyone know when you plan to arrive or leave each day (as long as it’s within the windows described above). Need to come in later one day and earlier the next? Go for it!
Employees generally still have access to the office outside of the 7-7 working window, but working outside of these hours should be reserved for extreme circumstances (like a software outage that needs immediate attention). However, feel free to enjoy the games or game tables at the office anytime with friends + family!

Yeltsin fails to punish journalists murderers
By Catherine A. Fitzpatrick
Although Boris Yeltsin won the Russian presidential elections, the Russian media --which opted unabashedly to back the president--may have lost.
Paradoxically, while the independent media have thrived under Yeltsin in many ways--to the point where lionizing the president was considered a free editorial decision--the press has suffered its most violent attacks in decades. CPJ has confirmed that 13 journalists have been assassinated since 1994, and four are missing and presumed dead, making Russia one of the most dangerous countries in the world for journalists. Through his governments failure to fully investigate, let alone prosecute, these cases, Yeltsin has signaled that reporters may be killed with impunity.
These attacks do not necessarily emanate from the presidents office, but stem from his historical lack of control over the "power ministries" (army, police, and security), and from the ministries failure, in turn, to control violent groups in society. The much ballyhooed "clean sweep" of corrupt ministries by new security chief Gen. Alexander Lebed is no substitute for the institutionalized watchdog function of a free press. Nor does it address the dangers faced by journalists who probe topics like corruption in the army or in business. In 1996 alone, three journalists were gunned down in or near their homes, and three were assassinated in Chechnya. Several more were brutally beaten, and others narrowly escaped assaults or were threatened.
In 1995, RUFA correspondent Natalya Alyakina was shot by a Russian soldier after being waved through an army checkpoint during a Chechen hostage crisis. Following a bungled investigation, the soldier received a suspended two-year jail sentence for "involuntary manslaughter through negligent use of a weapon." Yeltsin and other high officials failed to make good on their highly publicized promises to see justice done.
In March of this year, Nadezhda Chaikova, a prominent Obshchaya Gazeta war correspondent known for her exposés of Russian military atrocities and her close contacts with the Chechen resistance, was found murdered execution-style in a Chechen village. Russian federal troops are suspects, but Chechen leaders themselves may have ordered her death, believing she was a spy and acting on rumors spread by the KGBs successor, the Federal Security Service (FSB).
Many journalists confirm the FSBs role in discrediting those who report on Chechnya or other security-related topics. Summonses for "chats" at the FSB and invitations to collaborate--or face career difficulties--are still a fact of life, which journalists fear publicizing. One reporter, for instance, was warned to stop covering a controversial story "or else your personal security cannot be guaranteed."
The military is notorious for pressuring journalists. Izvestia correspondents have been coerced to "share information" with military prosecutors and other authorities. Editors at the feisty Moskovsky Komsomolets have yet to make public their allegations about the murder of fellow reporter Dmitry Kholodov, killed by an exploding briefcase in 1994 while following up on a tip about army corruption. And Juliya Kalinina, another journalist from the same paper, recently received anonymous threats for reporting on military officers abuse of power.
So it is not surprising that journalists have greeted Lebeds personnel purges with skepticism. Without the prosecution of reporters attackers, and a credible guarantee of safety from law-enforcement officials, journalists in Russia will not be free to provide the kind of probes into official corruption so necessary to a democratic society. Those in government who stand aside while reporters are killed with impunity cannot be credited with sincerely addressing the crisis facing Russia today.

Because this is undefined behavior: compiler can do everything, including returning expected value.
"Destroying" a variable is means running its destructor and freeing its memory. As primitive types destructor does nothing, it does not change its value.
If you access desrtoyed variable following can happens:
1) Memory where variable or some of its parts resided is returned to OS. Attempt to access it will cause crash.
2) Memory is still belongs to program and nothing touched it: you get old values stored there, you can write and read again and everyrthing will seem to work.
3) Memory is still belongs to program, but was overwritten: you will get something else for primitive types and can even crash program for complex types
4) Memory is given to other object: as (3), but writes to that memory will corrupt other objects.
5) Something else.
In your case (2) happens. Due to how program stack works and how compilers tend to generate code if optimisations are turned off, this is expected.
In one of PMs I sent a program which I claimed can output three different values. Did you try to compile it? It will show case (3): memory returned pointer points to gets overwritten.
The memory is available for reuse but not physically destroyed. If it has not been reused, it may work. But it is still undefined behavior. It could do anything and still be compliant with the language standard. One of those anything's is to print out the value that was assigned in the child function.
If the particular compiler is using a stack for storing its automatic variables, then that is a possibility. However, one cannot depend on a compiler using a stack. (Stack is not used in the standards.) Especially since bar is returning void and foo is not. Or if they had different parameter lists, it would not work.
This is why the standard simply says undefined behavior so various conditions do not need to be defined. So do not depend on any particular behavior. Because it could change with a different set of options on the compiler, or a different version of the compiler, or a project team which decides to change compilers.

In this chapter we look at two integrated development environments (IDEs) for Python on Windows:
PythonWin provides IDE capabilities for Python on Windows. It has a number of features in its environment that make editing and debugging Python code more pleasant and productive than standard text editors. Because the IDE features are part of the PythonWin package, you can take advantage of them if you develop your GUI application using PythonWin or if you extend your existing C++ MFC application by embedding PythonWin. More detail on the PythonWin framework can be found in Chapter 20.
IDLE is an IDE developed by Python author, Guido van Rossum. IDLE uses the Tkinter GUI framework and is portable to all Python platforms with Tkinter support. IDLE is a standalone IDE for Python; it doesn't attempt to provide a GUI or application framework. IDLE would be particularly suitable if you develop your GUI applications using Tkinter or regularly use Python on operating systems other than Windows. Guido has kindly assisted in the section of this chapter devoted to IDLE.

Volkswagen provided three nights in a hotel and air travel from Los Angeles to Washington, DC, for this story.
The prophets of doom are right; the auto show is fast becoming a spent force. I’ve been resistant to that idea, but this year’s LA Auto Show was as lackluster an event as I can remember. There was big car news these past days, all of which took place in LA: the Ford Mustang Mach-E, Volkswagen ID Space Vizzion, and of course the Tesla Cybertruck all made waves. But each met the public at an off-site event, and the Ford and VW were old news by the time the doors to the convention center opened for the first press day on Wednesday.
But we’re not going to focus on negativity today. Instead, we’re going to celebrate some of the four-wheeled eye candy at the show. The OEMs might not have brought much new to LA, but many of them did wheel out their takes on the future. Some are next year’s model with some added greebles, others are a view of a decade or more from now and require enabling technologies that aren’t quite there yet. Two are just race cars, built for SEMA and brought along to LA to make up the numbers.
No mind—I asked photographer Brian Won to walk the halls and, like the video game said, try to catch them all. And he did, with a couple of exceptions; BMW had put away its MNEXT, and Kia's Futuron was also hiding somewhere. Most of the captions are his, and I urge you to check out the massive gallery at the top of this article—the pictures are where it's at.
Of the concepts captured by Brian, I think my favorite has to be the Vision Mercedes Simplex. It's inspired by the Mercedes 35PS—the original Mercedes—built by Emil Jellinek in 1901. It "symbolizes the transformation of the brand-specific luxury of Mercedes-Benz" according to Chief Design Officer Gorden Wagener. I don't entirely believe that, but I love the elegance of the design and the pared-back detailing of this little open-wheel roadster.
Even the more out-there concepts have value. The supplier Magna used the show to announce the final of its first Magna Global Bold Perspective Award, which featured finalists from the US, China, and Europe, each looking 20 to 30 years into the future.
"The students' stuff happens at a 2D and model level and then it moves its way up. You can even see it in some of the form languages. Some of these ideas would be just amazingly out there, and then two years later somebody has a show car at Geneva," explained Larry Erickson, global director of design, Magna Exteriors. "Everybody's trying for something new, you know. There's always this pressure of what's next," he told Ars.
Zehao "West" Zhang, a student at ArtCenter College of Design in Pasadena, won the design with a vehicle for urban nomads.
Magna's interest in design as a Tier 1 supplier is a way of spotting trends as early as possible, in order to be able to offer the appropriate products to OEMs. Erickson pointed to active aerodynamics—air dams that lower at speed, or moving surfaces in a car's underbody that channel or skirt the airflow to cut drag—as ideas that are appearing in production cars now that were once the preserve of the concept.

There is an immediate need for resource allocation towards the Covid-19 pandemic. While there has been a wealth of data and scientists working to analyze, diagnose, and predict the spread of the outbreak, there has yet to be a centralized repository for harmonized datasets, immediate analysis needs, and previously completed research outputs. Here we are creating exactly this repository, for a decentralized and open source data science collaboration to combat the COVID-19 pandemic.
Use your skills to analyze data, develop models, and organize results so that policymakers are better informed to make the correct decisions. Another important task is maintenance of existing datasets to keep them clean and accurate. As of March 18th 5:30 PM, the number one most used dataset has 466 issues that need to be addressed.
State by state or regional in focus instead of just national. Maybe even try to predict patient flows to specific hospitals, which is maybe the single most important output for planners
Track if/how stimulus is or isn’t arriving at households e.g. changes in SNAP policy, sick leave, paid parental leave, etc. Track the allocation of dollars using supply side gov’t data. Track the receipt of dollars using household data and potentially social media.
Every policy idea is theoretical until it actually shows up in the surveys. This is essential for accountability and identifying bottlenecks / exclusion / etc.
Where are the most vulnerable students (free reduced lunch, foster, etc.) among schools that have been shut?
Web crawl and social media scrape to have real time dashboard of food/medicine stock outs that could quickly shine a light for suppliers and policymakers
Predict types of people that don’t believe efficacy of social distancing, etc. in order to target public health messaging better. Monitor false information on social media.
ER docs need an anonymous and fast way to share information and findings.

Preparation time
less than 30 mins
Cooking time
30 mins to 1 hour
Serves
Makes 8 puddings
Dietary
A perfect end to an autumn dinner party, these easy steamed puddings are rich with toffee and apples.
Preheat the oven to 180C/350F/Gas 4.
For the sponge, beat the butter and sugar together in a mixing bowl until pale and fluffy.
Crack in the eggs, one at a time, beating each egg into the mixture until fully incorporated before adding the next.
Fold in the flour until well combined. Add a splash of milk to loosen the mixture, as necessary. (NB: The mixture should be of dropping consistency.) Fold in the ginger.
Place the chopped apples and sugar into a pan and cook for 4-5 minutes, or until the sugar has dissolved and is bubbling and the apple has softened.
For the sauce, bring all of the sauce ingredients to the boil in a pan, stirring constantly to form a smooth sauce that is thick enough to coat the back of a spoon. Remove from the heat and set aside to cool slightly.
Spoon a little of the sauce into eight dariole moulds. Divide the cooked apple equally among the moulds, then spoon over the sponge mixture.
Place the dariole moulds into a large, deep-sided roasting tray. Pour enough boiling water into the roasting tray to reach halfway up the sides of the dariole moulds. (NB: This is called a bain-marie.) Cover the tray with aluminium foil, then transfer to the oven and cook for 25 minutes, or until the sponge has risen and is pale golden-brown.
Turn out one sponge pudding onto each of six serving plates. Drizzle any remaining sauce around the edge of the plates. Drizzle the custard over the sponge puddings.


Kotlin 1.4 的兼容性指南
Keeping the Language Modern and Comfortable Updates are among the fundamental principles in Kotlin Language Design. The former says that constructs which obstruct language evolution should be removed, and the latter says that this removal should be well-communicated beforehand to make code migration as smooth as possible.
While most of the language changes were already announced through other channels, like update changelogs or compiler warnings, this document summarizes them all, providing a complete reference for migration from Kotlin 1.3 to Kotlin 1.4.
Basic terms
In this document we introduce several kinds of compatibility:
- source: source-incompatible change stops code that used to compile fine (without errors or warnings) from compiling anymore
- binary: two binary artifacts are said to be binary-compatible if interchanging them doesn't lead to loading or linkage errors
- behavioral: a change is said to be behavioral-incompatible if the same program demonstrates different behavior before and after applying the change
Remember that those definitions are given only for pure Kotlin. Compatibility of Kotlin code from the other languages perspective (for example, from Java) is out of the scope of this document.

Lesson Plan Title:CSRF User Prompt By-Pass
Concept / Topic To Teach:
This lesson teaches how to perform CSRF attacks that by-pass user confirmation prompts.How the attacks works:
Cross-Site Request Forgery (CSRF/XSRF) is an attack that tricks the victim into loading a page that contains a 'forged request' to execute commands with the victim's credentials. Prompting a user to confirm or cancel the command might sound like a solution, but can be by-passed if the prompt is scriptable. This lesson shows how to by-pass such a prompt by issuing another forged request. This can also apply to a series of prompts such as a wizard or issuing multiple unrelated forged requests.
General Goal(s):
Similar to the CSRF Lesson, your goal is to send an email to a newsgroup that contains multiple malicious requests: the first to transfer funds, and the second a request to confirm the prompt that the first request triggered. The URLs should point to the attack servlet with this CSRF-prompt-by-pass lesson's Screen, menu parameters and with an extra parameter "transferFunds" having a numeric value such as "5000" to initiate a transfer and a string value "CONFIRM" to complete it. You can copy the lesson's parameters from the inset on the right to create the URLs of the format "attack?Screen=XXX&menu=YYY&transferFunds=ZZZ". Whoever receives this email and happens to be authenticated at that time will have his funds transferred. When you think the attack is successful, refresh the page and you will find the green check on the left hand side menu.

How To Use VLC with Windows/ documentation version 2.0
Installation for Windows
If the subtitles and the video are not in sync then you will need to adjust the subtitle by delaying it or playing it ahead.
The new functions are the video file conversion and the record function which records a part of a video you're currently watching.
Media devices are compatible only with file formats their manufacturers set. VLC can convert different video files to what your device is compatible with and change the resolution of the video for more efficiency when playing. This function can be found in the media tab.
Here are some of the different video file types, we didn't go into all of them because there are many types and the fact that these are the most commonly used.
VLC can record a part of a video that is playing on your screen and saves it to a directory of your choosing. This directory needs to specified in the "Preferences/input - codecs" tab.
In order to fully utilize the program and understand it’s functions, we’ll need to look at how it is structured and how the different functions work.
The figure above illustrates how VLC is structured. The Program accesses the files uploaded by the user from the computers directory. VLC then on some of it’s functions creates a new file and save it on the users specified directory-folder.
VLC functions can be divided into two process, read and write. The read process reads the files uploaded by the user and plays it. When a video file is played, other processes can be used to overlay a subtitle file, and various postprocess effects (ie. color grading) the video. While reading the file, synchronizing both the audio and subtitles to the video is also possible. The function processes can be seen below.
Figure 3. Function Model.

Chris Brown, Summer Walker + London On Da Track Triple Up W/ Epic-Sounding SOMETHING REAL Banger
by Rosario HarperR&B singers Chris Brown and Summer Walker have a certified hit on their hands. The duo have finally come through on their London On Da Track-produced “Something Real” single.
On Friday, Walker and Breezy released their must-hear record to the masses.
Earlier in the week, London On Da Track gave everyone a sneak peek at the fire collaboration.
This week, Breezy jumped on Instagram to low-key confirm the rumored birth of his son.
According to reports, Brown and his girlfriend Ammika Harris are the parents to a newborn baby boy.
As we previously reported, Ammika Harris checked into Tarzana Hospital in Tarzana, California Wednesday night (Nov. 20) to prepare for the baby’s birth with Brown by her side the entire time. While this is Ammika and Chris’ first child together, this makes baby number two for Chris, who’s already a dad to 5-year-old Royalty Brown, the daughter he shares with Nia Guzman. (Gossip On This)
