Connecting Rubberband Library for use in HISE

[DanH]

@langermarc19 Did you ever manage to get this working?

[d.healey]

@DanH I got it slightly working but not really a while ago. However since Christoph implemented pitch/time stretching recently I haven't looked into it any further.

[DanH]

@d-healey is there pitch shifting? I'm not after time stretching for this product. I've used the Faust one but it's not quite good enough. It's for Scriptnode.

@DanH https://docs.hise.audio/hise-modules/sound-generators/list/streamingsampler.html#timestretching

[DanH]

@d-healey Yep not what I'm after for this but thanks (unless it can be repurposed for SN?)

[d.healey]

@DanH

(unless it can be repurposed for SN?)

I think this applies to scriptnode too

[Lindon]

@d-healey so to be as clear as we can:

With time stretching on...

• I have a little tune in C Major, it lasts a bar, I pitch it up to E, and it still lasts a bar...?

[d.healey]

@Lindon That's the idea

[DanH]

@d-healey so where are the pitch options? Can only see the timestretching options in the sampler voice settings

[Christoph Hart]

@DanH just enable timestretching and add a pitch modulator.

[DanH]

@Christoph-Hart Ok so this is like a breaking change if we want to add in time stretching to an existing project which also uses pitch modulations?

[Christoph Hart]

@DanH no, you just can't use "normal" pitch modulation when timestretching is enabled for the given sampler module.

[DanH]

@Christoph-Hart Ok thanks :)

But for real-time pitch shifting this algo isn't implemented in Scriptnode is it?

[Christoph Hart]

@DanH there's a stretch player node IIRC.

Oh, yeah realtime will never work, the latency is something like 100ms.

[DanH]

@Christoph-Hart you mean the latency in this algo? I'll see if I can get rubberband up and running in that case

[Christoph Hart]

@DanH nope, has the same or higher latency and sounds worse. You can't timestretch an incoming audio streaming with less than 100ms latency.

[DanH]

@Christoph-Hart so what do I want for real time pitch shifting? Tried the faust one but wasn't great...

[Christoph Hart]

@DanH no idea lol, but I also need a good realtime pitch shifter, so if you find a solution let me know :)

[DanH]

@Christoph-Hart I also tried the RNBO one, was ok. I'll see if I can try ZPlane or ZTX
