vocals

How do you remove vocals from audacity , anyone please.

you can’t always do this, it depends on the recording. See this tutorial from the manual: http://manual.audacityteam.org/o/man/tutorial_vocal_removal_and_isolation.html

dont you have videos that demonstrate how its done ?

We don’t have any official video tutorials.

There are quite a lot of video tutorials available on YouTube (and elsewhere on the Internet) but most of them are very poor, frequently using obsolete versions of Audacity and frequently inaccurate or just plain wrong! So please keep that in mind if you look for video tutorials.
