Hi, every time I try the vocal reduction and isolation effect on an mp3 file, it never works and it always shows “Nyquist returned the value: 120”. I’ve tried changing the settings on it and it hasn’t worked. I don’t have any plugins.
Which version of Audacity?
Which version of Windows?
Mono or stereo track?
How long is the track?
What is the sample rate of the track?
What are the exact settings that you are using in the vocal reduction and isolation effect?
