问题:

I have these files with the extension ".adc". They are simply raw data files. I can open them with Audacity using File->Import->Raw data with encoding "Signed 16 bit" and sample rate "16000 Khz".

I would like to do the same with python. I think that audioop module is what I need, but I can't seem to find examples on how to use it for something that simple.

Thanx in advance.
