If you like hyper chipmunks or slow motion robots then by all means, crank that dial! Remember that the further you go, the weirder it sounds. If you wanted to move a song in A up to B, you’d go up two half steps – or 200 cents. It is measured in cents which is a bit counter-intuitive, but it’s simple once you know the conversion.ġ00 cents is one half step. I usually adjust Effect Blend, Smoothness, and Tightness to 100%.Īdjust the Pitch knob to transpose the song up or down.
This will bring up a little window with four “knobs” – Pitch, Effect Blend, Smoothness, and Tightness. Scroll down to the second section called “Audio Unit Effects” and click on the one called “AUPitch.” This loads a pitch shift effect that can transpose the track.Ĭlick on the effect image to edit the settings. This will bring up a drop-down with many effect options. You should see a “rack” of effects like “noise gate” and “compressor.”Ĭlick on an empty effect slot. Then click from “browse” to “edit” under the track image. This is where you can start adding effects to the track for pitch shifting. Click on the “i” icon in the bottom right corner.
With the track selected, open up the track info. Or click the metronome box in the control bar to the right of the heads-up display. Go to the Control menu and uncheck the metronome box. It’s just going to be confusing unless you know exactly what BPM the tune is. This creates a new track from the imported song with an orange waveform. The cursor will get a little green plus sign next to it to show that you can move the file there. Click, drag, and drop the track into the dark-grey center of the GarageBand window. Open the OSX Finder in front of the GarageBand window and locate the track you want to transpose.
Delete all existing tracks if you start with a template (click to highlight then press “command” and “delete”). The first step to changing the pitch of an MP3 is to open GarageBand and create a new blank project file. I’m using the latest version of GarageBand as of September 2014.
