Set Raw Audio bitrate

I am using the onOneWayAudioRawDataReceived delegate to record raw audio. I can see the AudioRawData object has a bit rate property (I’m consistently getting 32k in my tests).

I have two questions:

  • Does this bitrate change throughout the call?
  • Is it possible to set the bitrate?

Which Windows Meeting SDK version?

Device (please complete the following information):

  • OS: Windows 11

Hi @tyler

this should be consistently 32khz throughout the meeting. Currently there is no setter for the sampling rate.

And what is the encoding?

The encoding is in PCM
16 bit

To give further context on this to anyone else having this issue, these arguments on ffmpeg did it for me:

ffmpeg.exe -f s16le -ar 32k -ac 1 -i input.pcm output.wav

Edited: For single-channel audio only. This wasn’t tested for multi channel.
