MONO, SEPARATE SEREO TRACK

Hi,
The questions about the tracks and the vocal remove are numerous, but I did not find in the various forums of answers concerning the “mono” function. Indeed, it seems that a certain number of modifications to the different menus have taken place in the most recent versions of Audacity.

For example: in the drop-down menu of tracks, “Mono” no longer exists, nor does “Separate stereo track”, …

I tried to use the items which seem to correspond to those in old versions, but the test is not really conclusive, especially when one wishes to remove the voice from a musical extract.
Thank you in advance for your clarification.

Best regards

If I understand your question correctly, you want to know about removing a voice from music. Up to date information about this can be found in the manual here: https://manual.audacityteam.org/man/tutorial_vocal_removal_and_isolation.html

Note that a lot of information on this subject found on the internet is either out of date or plain wrong.
