Before you start: Have your source audio saved on your device. The editor prepares the clip; follow the setup steps to use it for incoming calls.
Prepare the clip before opening GarageBand
This guide uses GarageBand on the iPhone to install a custom ringtone. You need the app and an audio file available in Files. Start with your own recording or another usable audio file, rather than a streaming-service link.
Use the iPhone Ringtone Maker to choose the section you want. For this GarageBand route, select MP3 from the export choices and save it to Files. Keep the edit within 30 seconds and use a name you can find easily.
The same tool offers M4R for other compatible ringtone-import workflows. This tutorial follows the MP3-to-GarageBand route all the way through, so you can complete the process on the phone.
Bring the audio into GarageBand
- Touch and hold the GarageBand icon and choose Create New Audio Recording. Open Tracks, select the audio track, then open the Loops Browser.
- In Files, browse for your saved clip. Hold it and drag it into Tracks.
- Adjust the region edges if necessary and move the region to the start of the timeline, leaving no empty space before it.
Play the project from the beginning. The first sound should be the phrase you chose in the editor. If the timing feels wrong, revise the selection before exporting.
Export and assign the ringtone
- Return to My Songs, select the project and choose Share, then Ringtone.
- Name the tone and tap Export. GarageBand offers to shorten audio that exceeds its 30-second ringtone limit.
- Choose Use sound as, then Standard Ringtone, or assign the result to a contact.
These installation steps follow Apple's GarageBand instructions. Button positions can differ between app versions; the linked illustrated guide is useful if your screen looks different.
If the sound is missing or starts late
A dimmed source in GarageBand may be protected or unavailable locally. Use an accessible file saved on the phone. For a late start, revisit the timeline and remove blank space before the audio.
Keep both the original recording and the trimmed MP3 until you are satisfied with the finished tone. That makes another edit easier if you later prefer a different phrase. Finish with a test call, since an editor preview does not confirm the phone's current ringing settings.
