Timestretch Artifacts
-
You can try to use the signalsmith CLI tool (or whatever they ship as a binary) to check your exact audio material. AFAIK I've not changed the internals of that engine too much instead of just wiring in IPP / VDSP and a few other small performance additions.
You can't expect parity with the sound quality of Elastique though. Rubberband sounds worse in my experience than signalsmith - v2 as well as v3.
There is also another timestretch library on the block - Bungee which has a pro version that claims to be on par with Elastique et al, so maybe that would be a contender.

@David-Healey so we have working tempo synched time stretch with this PR? or i should add..this wasnt working before if i remember correctly
-
@jeffd We already did, but now it's a little more user friendly and a glitch has been fixed.
-
@David-Healey i think last time i tried it it always crashed.
but that was awhile ago.
-
@jeffd Yes there was a crashing issue that the PR fixes
-
@David-Healey yeah, thats what happened when i tried it.
this is great that its fixed now!
-
@David-Healey What unit is SampleStart/SampleEnd displayed in inside the sample editor? Is it raw samples, or something else?
-
@dannycouture Yes, samples
-
wav file is 75600 samples (140BPM) confirmed in Audacity, HISE sample editor showing 82286 as SampleEnd. Is HISE adding padding on import? or maybe a bug?
EDIT:
Thinking this is the issue as to why I am hearing smearing even at 100% stretch. I set the SourceBPM to 140 and engine host to 140 and I still hear smearing like its slowing down 1BPM or so too with Timesync Mode activated. -
@dannycouture Send me the sample
