Transpose audio regions in GarageBand on Mac
You can transpose audio regions in the Audio Editor. Audio regions can be transposed up or down by up to 12 semitones. A semitone is the smallest distance between two musical notes. Notes with the same name repeat every 12 semitones, called an octave.
Transpose selected audio regions
- In the Tracks area of GarageBand on Mac, select the regions you want to correct. 
- Make sure the Region button is selected in the Audio Editor inspector. 
- Drag the Transpose slider left or right to transpose the regions in semitones.
