Answer 1

You can use PySoundFile to open the file as a NumPy array and play it with python-sounddevice.

import soundfile as sf
import sounddevice as sd

sig, fs = sf.read('myfile.adc', channels=2, samplerate=16000,
                  format='RAW', subtype='PCM_16')
sd.play(sig, fs)

You can use indexing on the NumPy array to select a certain part of the audio data.
