Ableton Live has a very clever (to my uninitiated mind) approach to efficient/pragmatic modulation and warping of audio clips.
Specifically, I'm talking about how when you're aggressively modulating/re-tempoing the heck out of an audio clip that uses the Beats Warp Mode. The way it works internally is that according to audio transients that are automatically detected by Live (and manually editable), the clip is essentially split up into segments, and when a clip is played at a faster tempo, it maintains the same pitch by essentially dropping audio before the next transient, and when played at a slow tempo, it cleverly fills in the gaps, usually by replaying backwards+forwards the region of audio before the next transient (this too is configurable).
In the case of modulating, it combines this approach (I think) with simple resampling (which is efficient / good-enough quality); any leftover tempo gaps after the resampling are dropped/compressed using the same Beats approach.
As a programming nerd, I find this to be exceedingly clever, but since I don't know much other than Ableton, I'm wondering if this is a concept that originated with Ableton or if there was prior software that pioneered this approach?
