audioop.findfactor(fragment, reference) Return a factor F such that rms(add(fragment, mul(reference, -F)))
aifc.setpos(pos) Seek to the specified frame number.
audioop.lin2ulaw(fragment, width) Convert samples in the audio fragment to u-LAW encoding and return this as a bytes object
Wave_write.setnchannels(n) Set the number of channels.
audioop.avgpp(fragment, width) Return the average peak-peak value over all samples in the fragment. No filtering is done, so
