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. If you are on PC, you can do a similar thing in Audacity, but the process will be slightly different. The one for iPad or iPhone doesn’t do what we need it to do. With GarageBand you can move the key of the recording up a half step into the key of C so that you can play along.įirst of all, you need GarageBand for OSX. For instance, I’m Yours by Jason Mraz is recorded in the key of B, but most people play it in C on the ukulele. Many times there is a perfect ukulele key for a song and it’s not always the same as what was recorded. This can be useful for transposing the key of a recording that you are trying to learn. You might want to turn off snap to grid mode and zoom in real close when making the edits! Depending on how close the starting point of your audio file was to the first downbeat of the music in it, you might have to do some fine editing in order to make sure it lines up and plays completely in sync. Double-click on the track you want to speed up or slow down (your track should turn purple) 4. Deselect all audio tracks in GarageBand 2. Changing the tempo of a track allows you to increase the speed of track vocals or slow down the lyrics of a song in GarageBand. Then turn on “Follow Tempo & Pitch.” Now go to the LCD display the bottom center. Double-click on the track and you should see the audio region settings appear at the bottom left. The way to change the tempo is to first lock the Tempo & Pitch of the track, and then increase the tempo of the whole song. Question: Q: How do I change the pitch of a song by a 1/2 step in the new Garageband? I used to use AU Pitch, and change the Cent by 100 to raise the pitch of a song, so I could practice to it without retuning.

GarageBand can do many, many things, but today I’d like to walk you through how you can use it to change the pitch of an MP3 file.
