To choose the sampling rate set the Content-Type property to audio/l16;rate=16000 or audio/l16;rate=8000 depending on if you need the data at 16kHz or 8kHz. Most real-time transcription services work best with audio at 8kHz. Each message will be a 20ms sample of the audio from the call. If you choose the 8kHz rate each message will be 320 bytes.

You need to make sure that the audio buffer is sampled at 16 kHz (more on this later). In my experience the AudioContext sample rate in Chrome and Firefox is 44100Hz (the same sampling rate as used for compact discs (CDs)) but this can vary based on the recording device. The following function down samples the audio buffer to 16 kHz.
