Hello, what is the expected audio format input to the NeuroSync Player? I am trying PCM16 24kHz but I dont think it is working.
it needs to be wav, not pcm 
IIRC, you can make a playable WAV out of the raw PCM data array.
Yes, you can do that before its sent to the api or add a converter into the api if you know the sample rate is going to be the same each time.
Currently, it requires wav because it upsamples to 88200 regardless for the feature extraction - this is to allow for variance in the sample rate to be more easily dealt with (as you can tts in or mic in, the higher the sample rate the better the face shapes from the audio).
The python really is a guide on how you might use it, not production code for use in a project as is - an application is under development for those not confident with implementing thier own solution.
