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:
['x00x00x00x00xffxffx00x00x00x00', 'x00x00x00x00x00x00x00x00x00x00', 'x00x00x00x00x00x00x00x00x00x00', 'x00x00x00x00x00x00x00x00x00x00', 'x00x00x00x00x00x00x00x00x00x00']
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 'x00x00x00x00xffxffx00x00x00x00'
? 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.
