2.3.0. A vocal recorded onto an instrumental and I’m trying to slide the vocals forward and/or backward to line up with a particular beat. Thanks.
If you have the vocal and instrumental on separate tracks, select the vocal by clicking just right of the up arrow.
And use the Time Shift Tool (two sideways black arrows) to slide the track left and right.
Audacity will combine the two into one mix when you export, or you can create a forced mix with Tracks > Mix > Mix and Render to a New Track.
If you have a mixed show, everything on one track, that’s the end of the world.
