Using GarageBand to transpose music tracks

August 26, 2009

[First posted at MyRightBrain]

My fellow liblogarian, Von Totanes, aka Filipino Librarian emailed me to ask if I knew how to use GarageBand to transpose an imported MP3 from F key to E key. He’s new to GarageBand and said he tried searching for help but couldn’t “make heads or tails of what’s being said”.

I know of two ways to do it in GarageBand: using the “AUPitch” effect or the “Vocal Transformer” effect.

My GB version is iLife ’08. If you’re using a later version, the user interface may be slightly different but the effects should be the same.

BTW, I presume you’ve already imported the MP3 to GarageBand. Once that’s done, select that track and apply either one (but not both) of these effects:

#1 – Using the “AUPitch” effect

AU Pitch

[I don’t think the numbers represent the pitch, because how much you adjust depends on your original pitch. So you’ll have to experiment. Like, play a note on the piano or a song with a known pitch.]

#2- Using the “Vocal Transformer” effect

Vocal Transformer

      Hi Shelly, thanks for dropping by! I was just contemplating the closure of this blog. Maybe I should keep it for now 🙂 Cheers.
