I have implemented the WSOLA time stretching algorithm for audio data, but there are still many artifacts from the stretching.
I don't actually care about maintaining pitch and am totally ok with the "chipmunking" effect. What options are available for time stretching in this case? Are there any algorithms I can use that will produce fewer artifacts?
I've only been able to find questions that DO care about maintaining pitch. I've read about resampling, but don't understand exactly how that would work when not trying to double or halve the speed of the sample.
Any information or links are appreciated!
