Auto tuning has become a widely-used tool not just in homemade music production but within the music industry itself. Auto tuning enables you to rework a piece of recorded vocals and improve the pitch of the notes throughout the track.
GarageBand will analyse a vocal recording and register the key in which each note is sung throughout the recording. The tool will then compare the note with that of the key that the instrumental section of the song is being performed in. GarageBand will shift the notes of the vocals to correspond, putting the vocals in perfect key. That may sound complicated but GarageBand does everything automatically with its Auto Tuning tool.
1. Project settings
Open GarageBand and select New Project. Select Voice from the modes then click Choose. Title your track and select a time signature, BMP and Key.
3. Vocal mode
Click Create. Once the interface is opened click Real Instrument in the Track Info window. Click Vocals and select a vocal type. Adjust the recording options below the categories.
3. Record instruments
Click the + icon in the bottom-left corner to add instruments. Select an Instrument type, such as Real Instrument then click Create. Record as many tracks as necessary.
4. Record voice
Once you’re ready, record your vocals by clicking the Record button. When finished, click the Track Editor icon in the bottom-right to view track editing options.
5. Project adjustments
In the Monitor window, click on the icon to the right to change modes. Select Project mode. This gives you more control over the key, tempo and time signature of your piece.
6. Check your key
In the Monitor Window, click Note underneath the Key subheading. Here you can change the key that your instruments are playing in. For accurate auto tuning the key must be correct.
7. Auto tuning
In the Track Editor beneath the Timeline, drag the dial to the right underneath the Automatic Tuning subheading. Go up to 100 to compare the results against having no auto tuning.
8. Auto tuning adjustments
Play through the song, adjusting the auto tuning to balance between in-tune singing and an authentic sound. The more out of tune the singing, the more auto tuning is needed.
9. Limit to Key
Tick the Limit to Key box to force the auto tuning to stick to the tuning you set the song to. This will tune your vocals to the same key that the instruments are playing in.
