Encoding audio data

[TheHacker707]

Hello, I want to be able to read the contents of a .wav file, decode it into a list of ints, analyse it/modify it, and then encode it and save it back as another .wav file. I can load and decode it so far, but I can't figure out how to encode it again. I was thinking something like

int.to_bytes()

Here's my code:

#!/usr/bin/env python3

import wave, pyaudio, soundfile

filename = 'testfile.wav'
file = wave.open(filename, 'rb')
c, ss, fr, f, ct, cn = file.getparams()
frames = file.readframes(c * ss * f)
data = []
for i in range(len(frames)):
    item = int.from_bytes(frames[i:i + 1], byteorder='little', signed=True)
    data.append(item)
