Hi,

For the audio send stream we currently support signed 16 PCM with a sample rate of 16Khz. There are 2 sizes of buffers that we expect 10ms and 20ms so respectively 320 bytes and 640 bytes, for the size of the audio buffers. Can you please share more details on the wav file? As I mentioned it has to be mono 16 PCM.

Thanks.
