Converting android m4a to wav in python

processing.py

for i, m4a_buffer in enumerate(m4a_buffers):
    f = tempfile.NamedTemporaryFile(dir=voice_datadir, suffix="."+input_audio_extension, prefix="%s_%d"%(username,i), delete=True)
    f.write(m4a_buffers[i])
    f.seek(0, os.SEEK_END)
    chunk = AudioSegment.from_file(f.name, "mp4")
    chunk.export("%s_%d.wav"%(username,i), format="wav")

Thank you for sharing this code,
Can you please help me understand what do you mean with "m4a_buffers"
Are you creating a list of frames by parsing the m4a file based on it's sample rate? if that's the case, how do you do that ? if not , can you help me implement that code ?
Thank you
