Bug in Vocal reduction and isolation

Post by Felipe Zanabria » Sat Mar 20, 2021 12:22 am

Greetings! I experience an error in this effect when executing the functions that do FFT operations. The only functions that work correctly are those that return mono audio, and the analysis function. I have tried a plug-in from a previous version and it also gives me an error. The conclusion I came to is that there is a problem in Nyquist's internal functions. Below I attach the debugging report.

For convenience I'm displaying the first part of the error as text:

When opening the effect, select any option. Eliminate vowels, isolate vocals etc, except for the analyze option and those that return mono audio. When applying, you will see that the effect does not process the track. To make sure there is an error, press the debug button.

If you try to run the function analyze, remove vocals to mono, or remove center to mono, the plug-in works fine.
