Do you mean looping an extract of a sample? Then I would suggest to
take a look at the phase-locked vocoder example in Puredata. It works
well to freeze, stretch and pitch-shift a "wave cycle".
The original paper:

I believe there's now a way to run PureData patches from the command
line (without a GUI).
