Hey Owen,
Yes, there's definitely errors in our resampling code, at least one
due to the fact that we handle the playback position in EngineBuffer
as an integer instead of a float. (When you're stretching, you can
have the playback position be a fraction.) You would expect any sort
of error like this to be more noticeable with higher sample rates and
lower latencies.
I don't think RJ nor I have any plans (yet) to fix this properly. If
you wanted to try working on it, trying to fix the above in
EngineBuffer might be a good place to start.
Thanks,
Albert
