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)

There is a very useful google sheet with a matrix for the &proaudio (&stereo) parameter:

Audio Bitrate

Options to control the audio bitrate:
  1. 1.
    Add &proaudio to the source AND view link to get 256-kbps (echo cancellation, noise suppression and auto gain are then DISABLED)
  2. 2.
    Add &proaudio to the view link to get 256-kbps (echo cancellation, noise suppression and auto gain are still ENABLED)
  3. 3.
    Add &oab=100 to the source link to get 100-kbps
  4. 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:
To see the audio bitrate Right-Click -> Show Stats or Control (Command) + Left-Click on a video source
