[LAU] loop speeding in sample level accuracy

[Jari Suominen]

Hello,

I'm trying to search a program (with no success) that could used for 
speeding up an audio file to a certain length. I mean, I would have a 
audio file that has 40000 samples, and I would need it to be 40010. And 
the pitch of the file can/should change. All speed change stuff that I 
have found will take semitones/cents/procents as a input parameter. I 
would wan't to only input the exact length (in samples) that I need.

My purpose is basically make bunch of files that are loopable and have 
equal length with each other.

Does this thing exist or do I have to make it myself?

Thanks!
