Timestretching/Pitchshifting

@Lindon Need to update your VI thread :)

@Christoph-Hart Much appreciated Christoph!

[audiolyf]

@Christoph-Hart Nice! Is getTimestretchOptions() not implemented yet?

[d.healey]

@audiolyf I can see it in the repo - https://github.com/christophhart/HISE/commit/3c8711f0713f445d197fa6b7d8f9e4819de114f6#diff-92b4316aaf5f04995603daa0550fbbb9156f53dbb5061d9608eacb18fb356d73

Thank you Christoph Hart for this feature. My project was stuck, but now the problem is solved! Don't you think @d-healey that it would be interesting to offer a tutorial on your YouTube channel to explain how to properly implement time stretching? It could help more than one person.
Thanks,
Remi Dufeu

@d-healey Pulled the branch yesterday and everything else is there but I'm getting function not found both with getSampler and getChildSynth

[d.healey]

@audiolyf Maybe you pulled before Christoph added it?

Definitely, once it's a little more mature.

[Christoph Hart]

@d-healey there‘s not much to show in a tutorial - just turn on timestretching and set the ratio…

[d.healey]

@Christoph-Hart I think they'll want to know how to use the scripting functions and implement a UI.

[audiolyf]

@Christoph-Hart Sample start mod is not possible, right?

[Christoph Hart]

@audiolyf Actually I just have forgot to take that into account but that's fixed now (along with a lower stretch limit of 0.0625 instead of 0.5).

[audiolyf]

@Christoph-Hart mf king!

[Christoph Hart]

I'm thinking about adding this to the AudioLooper too (it's pretty obvious that this might be useful there). Is anybody using the tempo synced mode in a real project? It previously changed the pitch to match the tempo but I guess that is so totally useless that I can replace the functionality and enable timestretching by default when the tempo syncing is activated.

@Christoph-Hart

Is anybody using the tempo synced mode in a real project?

Yes, and I added new modes for longer loops (I think you merged this already). But real time stretching will be so much better.

However the main limitation of the loop player is that you can't edit the loop points. So I've switched over to the sampler with custom import now. The only problem there is every time I change a parameter the loading callback gets triggered.

It would be greate if we could use time stretch for FX and slowdown incoming signal :)

[d.healey]

@parabuh You can can't do this with scriptnode core.stretch_player

[Christoph Hart]

No the stretch_player still requires an audio file. The problem is that there is a latency of 50-100ms which makes it unsuitable for realtime processing of the audio input.

[d.healey]

Noticed a strange UI glitch, xfade table is missing.
