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 tab is selected in the Audio Editor inspector.
Drag the Transpose slider left or right to transpose the regions in semitones.
Thanks for your feedback.
