iPhone: an audio-import workflow with GarageBand
Download M4A and save it to Files. In GarageBand on your iPhone, open an Audio Recorder project, switch to Tracks, and use the Loops browser’s Files tab to import the clip. Place it at the beginning, keep it within 30 seconds, then return to My Songs. Share the project as a Ringtone, export it, and choose Use sound as.
M4R is also available for compatible tone-transfer workflows; downloading it alone does not install it. Do not assume every iOS version has the same sharing options.

Android: select your downloaded audio
Download MP3, open Files by Google, and find the file under Audio. Open its More menu and choose Set as ringtone. If prompted, allow the app to modify system settings. Alternatively, choose the downloaded file in your phone’s Sound settings.
For an individual contact, notification, or alarm, use the corresponding contact or app settings. Available options vary by phone and app.
