How to split a .wav file into multiple .wav files?

Question

I have a .wav file several minutes long that I would like to split into different 10 second .wav files.

This is my python code so far:

import wave
import math

def main(filename, time):
    read = wave.open(filename, 'r')

#get sample rate
    frameRate = read.getframerate()

#get number of frames
    numFrames = read.getnframes()

#get duration
    duration = numFrames/frameRate

#get all frames as a string of bytes
    frames = read.readframes(numFrames)

#get 1 frame as a string of bytes
    oneFrame = read.readframes(1)

#framerate*time == numframesneeded
    numFramesNeeded=frameRate*time

#numFramesNeeded*oneFrame=numBytes
    numBytes = numFramesNeeded*oneFrame

#splice frames to get a list strings each representing a 'time' length
#wav file
    x=0
    wavList=[]
    while x+time<=duration:
        curFrame= frames[x:x+time]
        x=x+time
        wavList.append(curFrame)

Printing wavList yields:

['\x00\x00\x00\x00\xff\xff\x00\x00\x00\x00', '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00', '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00', '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00', '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00']

I know that this is a list of frames. How do I make one wav file for each element in this list (the first .wav file would be '\x00\x00\x00\x00\xff\xff\x00\x00\x00\x00'? Python's wave module is unclear about using frames to create .wav files.

EDIT: This is a duplicate question of How to splice an audio file (wav format) into 1 sec splices in python? However, if someone has an answer that does not require pydub I would very much like to see it.

Answer 1

This is a python code snippet that I use for splitting files as per necessity.
I use the pydub library from https://github.com/jiaaro/pydub. You can modify the snippet to suit your requirement.

from pydub import AudioSegment
t1 = t1 * 1000 #Works in milliseconds
t2 = t2 * 1000
newAudio = AudioSegment.from_wav("oldSong.wav")
newAudio = newAudio[t1:t2]
newAudio.export('newSong.wav', format="wav") #Exports to a wav file in the current path.
