Looking for microphone audio format

[1Jamie]

When using amoled.startmicrophone and grabbing audio from it, what format, samplerate and codec is the audio using?

I am trying to take audio from the t-glass and send it over to a speech to text server and then send back the transcription to display but I am unable to ascertain the formatting to properly reformat to the models desired setup.

That did the trick, thank you very much for the information. I was able to get speech to text working and displaying on the t-glass thanks to this info.
