Audio Filters & Bitrate

A guide on how to use Audio Filters & Bitrate in VDO.Ninja
Filter Options
There are several Audio Filters in VDO.Ninja. Some of them are turned on by default, some are not. To activate these Audio Filters you have to add them to the source side.
So for example:
https://vdo.ninja/?push (for a basic push link)
https://vdo.ninja/?room=SOMEROOMNAME (for a guest in a room)
Name
Parameter
By default
Change the default setting
Outbound Audio Bitrate
​&oab​
32-kbps
&oab=XX (0-510 kbps)
Pro Audio
​&proaudio​
off
&proaudio
Master Gain
​&audiogain​
100%
&audiogain=XX (0-200 %)
Auto Gain Control
​&autogain​
on
&autogain=0
Echo Cancellation
​&aec​
on
&aec=0
Noise Suppression
​&denoise​
on
&denoise=0
Noise Gating
​&noisegate​
off
&noisegate
Compressor
​&compressor​
off
&compressor
Limiter
​&limiter​
off
&limiter
Equalizer
​&equalizer​
off
&equalizer
Lowcut
​&lowcut​
off
&lowcut=XX (in hz)
Microphone Delay
​&micdelay​
0-ms
&micdelay=XX (in ms)
Adding &proaudio to a source link disables Auto Gain, Echo Cancellation and Noise Suppression, sets the audio to stereo and the possible outbound audio bitrate to 256-kbps
the &proaudio parameter is the same as the &stereo parameter
Default settings of VDO.Ninja:
​
There is a very useful google sheet with a matrix for the &proaudio (&stereo) parameter:

Audio Bitrate
Options to control the audio bitrate:
1.Add &proaudio to the source AND view link to get 256-kbps (echo cancellation, noise suppression and auto gain are then DISABLED)
2.Add &proaudio to the view link to get 256-kbps (echo cancellation, noise suppression and auto gain are still ENABLED)
3.Add &oab=100 to the source link to get 100-kbps
4.Add &audiobitrate=200 to the view link to get 200-kbps
&proaudio overrides the bitrate of &oab if set on the source AND view link or only on the view link -> you get 256-kbps.
&audiobitrate overrides &proaudio and &oab
This also works for &room on the source side and &scene on the view side if you are in a room.
Some examples:
1)
https://vdo.ninja/?push=SOMESTREAMID
https://vdo.ninja/?view=SOMESTREAMID&proaudio
-> 256-kbps
2)
https://vdo.ninja/?push=SOMESTREAMID&oab=100
https://vdo.ninja/?view=SOMESTREAMID&audiobitrate=200
-> 200-kbps
3)
https://vdo.ninja/?push=SOMESTREAMID&proaudio
https://vdo.ninja/?view=SOMESTREAMID
-> 32-kbps
4)
https://vdo.ninja/?push=SOMESTREAMID&proaudio
https://vdo.ninja/?view=SOMESTREAMID&audiobitrate=96
-> 96-kbps
