Description
I am not able to send audio to a meeting using Pcm44KStereo format, but I am able to do it using Pcm16K. From the docs, I understand that the stereo format is for convenience, and the left and right channels have actually the same information. Does this also hold for the sample rate? I mean, is the 44K format a resampled version of the 16K audio? As using Pcm16K for sending forces me to also use Pcm16K for receiving, I want to understand if I will lose quality or just convenience. Thanks!
Edit: I just found this answer which I think reinforces my hypothesis, but I would love to have confirmation if we always get audio in 16K and it gets resampled by the SDK.

Research direction
Review the audio-format documentation and the linked answer in issue #51, focusing on Pcm44KStereo, Pcm16K, and the SDK's resampling behavior. Done means confirming whether audio is always received at 16K, whether Pcm44KStereo is resampled, and recording that clarification in the relevant documentation.
