Effect > Vocal Reduction and Isolation...does not populate the drop menu???

Need help…supposedly the Nyquist Vocal Reduction and Isolation
Audacity includes a Nyquist plug-in effect to automate the steps involved in Case 1, at Effect > Vocal Reduction and Isolation… This does not show up in the Effect tab…where is it…how do I turn it on? Already tried doing the add plug ins…still did not work

Can anyone help?

thnx, S. Harden :unamused: :ugeek: :ugeek: :neutral_face:

Which version of Windows?
Which version of Audacity? (look in “Help > About Audacity”)
