martel I have a backing track with very faint vocal in background. Can stage Traxx be used to increase just the voice volume?
peter No, if you have a stereo backing track it is not possible. With a multitrack song where the vocal is on a separate track, you can do that.
davedroug go onto https://vocalremover.org/ upload your song into vocal remover , it will then split the track into two .MUSIC TRACK 1// VOCALS TRACK 2 .each track has individual volume, just alter the volumes until you have the right balance. then download your edited mix or download both tracks and edit it in a DAW
