The recent 5.60 update added a new Time/Pitch library called Rubber Band. I didn’t have the time to compare it to the other algorithms in the last “What’s New” video so in this video we’ll do just that.
I’ve set up a stress test for these algorithms where their glitches/artifacts are most obvious. In real-world use the artifacts are much more subtle. If there is demand we can do more of these tests.
Source sounds – Drum loop, synth Pad/stab, and seal vocal (the animal).
Algorithms – Elastique 3.2.3 Pro; Elastique Soloist; Elastique Efficient; Rubber Band; SoundTouch High Quality; Simple Windowed 50ms, 50% fade; CDP extension Stretch Time mode.
Test parameters – Items stretched to 4x length/0.250 rate
