I prefer unpacking the contents of the wave file into an array and editing by cutting the required segment of sound from the wav file,as i am working on speech processing,and guess this way would be easy to enchance the quality of sound later...

can ne one suggest a way for this?? Plz help..

Thanks in advance.

There are a few libraries you can use for handling media files in general, eg. pymedia. However if all you need is support for simple WAVs, you could probably just use the built-in wave module.

import wave
win= wave.open('sample.wav', 'rb')
wout= wave.open('segment.wav', 'wb')

t0, t1= 1.0, 2.0 # cut audio between one and two seconds
s0, s1= int(t0*win.getframerate()), int(t1*win.getframerate())
win.readframes(s0) # discard
frames= win.readframes(s1-s0)

wout.setparams(win.getparams())
wout.writeframes(frames)

win.close()
wout.close()
