I am a new user and need some help with using Audacity. I would like to remove the guitar part or decrease it’s volume on a particular song so that I can play my guitar along with the song at home. I have seen YouTube tutorials that explain how to remove the bass guitar part and was successful in removing the bass from this particular song. I just can’t figure out how to remove the guitar part, if it can be done at all. This particular song is an instrumental with the guitar being the lead in the song. I have looked through the on-line manual but haven’t found anything that could lead me in the right direction. I would appreciate any tips that might help. I am using OS X version 10.11.6, the 2.1.3 version of Audacity, and installed Audacity using the .dmg installer.

Thanks in advance.

There’s a slim chance that either the Vocal Removeer or Vocal Reduction and Isolation effects may improve it a bit.

What song is it?
