Either a better implementation using SoundTouch, or else I&#39;m going to use<br />libRubberBand, which seems to be the more widely used timestretch library.<br /><br />Due to the resample to &quot;bars&quot; code, if you record some material, but not to precise bars lengths<br />it will be resampled (just a little bit) but will sound aweful in the harmonic sense :(<br /><br />See the following issue: https://github.com/harryhaaren/Luppp/issues/2<br /><br />Cheers, -Harry
