Hi guys,
I have a program that lets the user play a sound but i was wanting to know how i could make it so the user could vary the speed in which the sound plays so the sound can play slowly and quickly and normaly as well. Is this even possible with python? Becuase i was looking and i couldn't find any modules to help me with this problem but if anyone could give me a hand that would be greatly appreciated.
Thanks.

I don't know about python but the trick of doing this is increasing the tempo of music. If the current module you are using can do that then that will be simple case

Similiar to what evstevemd said, I was thinking you would need to change the sample rate (how many bits per second are played) if you take a 44000hz sample and play it at 88000hz, it should play at double speed.

Okay well got an update for everyone. I am using pyAudio and wave modules to play my .wav file. Now i can set the "Rate" in which the file plays. This i can change at the start of the program and it will change the rate at which the sound is played. This changes the speed and therefore the pitch. My issue is, with using pyAudio i haven't been able to work out how to change the rate while the application is running.
So if anyone knows how to do that. That will be very helpful.

I think a better option might be to switch to pySonic
http://pysonic.sourceforge.net
the Song.userspeed() property in particular looks like what you would want
