[bug] Timestretch causing pops and white noise

[d.healey]

When I enable timestretch on my sampler I'm getting pops/clicks and the occasional blast of white noise.

All I have in my test project is a sampler, and in the UI script I have this:

const var Sampler1 = Synth.getSampler("Sampler1");

// fetch the current state
const var obj = Sampler1.getTimestretchOptions();

// Apply your changes
obj.SkipLatency = false;

// Update the options
Sampler1.setTimestretchOptions(obj);

The samples are 16bit 41kHz.

In another project which uses 24bit 48kHz samples I don't run into the issue in HISE, but I get similar issues in the exported project. That one is using multi-mics and some of the mics don't seem to play at all sometimes when timestretching is enabled.

I encountered this problem not long ago. If Sampler enables timestretch, using Pitchbend will also cause this problem.

@Christoph-Hart Still getting nasty sounds with time stretching.

Here's an audio file rendered directly from HISE. You can hear the distortion at the beginning, this is just by enabling time-stretching for the sampler without changing the ratio.
