Practicum: Improving Vocal Quality
Technical Note
If you created multiple tracks for your final assembly, it is best to mix down the tracks so that all of the tracks you want to add the effects to are on one track. You can do this by using the mix function or export all of the tracks together to mix them down into one clip and reimport the audio.
To export and mix down multiple tracks, highlight all of the tracks you want to export and go to File, Export, Export Selected Audio. Select "Export Selected Audio."
