Thanks - there is a report of this here
https://github.com/breakfastquay/rubberband/issues/66 and I'll take a look at
it soon.
(I'm just catching up on issues and threads today after a few days away)

Re: [LAD] Rubber Band Library v3.0.0 released
Hi Chris,
I tried to load LV2 plugins into Carla.
There are 4 LV2 plugins. Carla loads plugins without "R3" in them.
But these 2 fail to load: Rubber Band R3 {Mono|Stereo} Pitch Shifter.
Carla says:
Failed to load plugin
Could not find the requested plugin URI in the plugin library
Carla-2.5.0
FreeBSD 13.1
Thanks,
Yuri

Indeed. And not only in terms of musical or aesthetic considerations as illustrated by the examples, but even in a fundamental mathematical way: there isn’t enough information in the signal to specify what should be the 'correct' result - this always involves a degree of subjective interpretation and choice. Which puts developing a library such as Rubberband on a very different level when compared to e.g. resampling or convolution for which at least the expected output is exactly defined. And that's one of the reasons why I consider Rubberband to be one of the true gems of open source audio software.

One small question: https://hg.sr.ht/~breakfastquay/rubberband/browse/rubberband.pc.in?rev=v3.0.0 states Version: 1.8.2 (not 3.0.0).

You pick one when you construct the stretcher object, and the rest of the API and the way you use it are identical. In principle to switch an application from one to the other is simply a matter of adding "| OptionEngineFiner" to the end of the options list when the existing code constructs its stretcher. (I say "in principle" because you would want to test it thoroughly and check that it is actually doing what you expect!) It is also usually a good idea to call the new function getEngineVersion() after construction to check you have the engine you expected, because that guarantees you don't accidentally get linked against an old library version that doesn't support the new engine.

Sound interesting :)
When you say higher CPU cost, can you give a rough estimate as to how much?
Is it possible to have both versions compiled, and for a host to switch between
them at runtime?
