Start with a file stored on your phone
Download an MP3 you have the right to use and open it in your phone's Files app. Play it once to confirm the file is complete, audible and stored locally. An audio link that only streams from a website is not the same as a downloaded file. If you want a gentle sound, browse instrumental ringtones, preview one and save its MP3. A ringtone can be used as an alarm only if your Clock app lets you select that local file.
Google Clock: add your own sound
- Open Clock and tap Alarm.
- Open an existing alarm or add a new one. Tap the current alarm sound.
- Choose Add new, then select Your sound file. Browse to the downloaded MP3 and select it.
- Return to the alarm, make sure it is switched on, and set a test time a few minutes ahead.
These controls follow Google's Clock instructions. A manufacturer's Clock app can use different labels or offer a different file picker. If you do not see Add new, confirm which Clock app you are using before trying a path from another device.
Samsung Galaxy: check the alarm's own sound control
On a Galaxy phone, open Clock → Alarm, open the alarm, and look for Alarm sound. Samsung documents this control and its volume slider in its Galaxy alarm guide. If a file picker or plus button appears on your model, select your locally saved MP3 and save the alarm. The exact picker varies by phone and software version; do not assume the Google Clock path applies to Samsung Clock.
If the alarm is silent or the MP3 is missing
- Check alarm volume, which may be separate from media and incoming-call volume. On Galaxy, inspect the slider inside Alarm sound. Test with the phone speaker at a safe volume.
- Make sure the alarm is enabled, scheduled for the correct day, and has a sound rather than Silent. Google notes that an alarm with silent sound and vibration off may not alert you.
- Find the MP3 in Files and play it there. If you moved or deleted it after selection, choose the file again from its current location.
- If the picker cannot see the MP3, move or copy it to a normal internal-storage folder and try again. Avoid relying on a temporary download or cloud-only file.
- Set a short test alarm while you are awake. A test catches the wrong alarm, wrong time, unexpected Bluetooth output and an inaudible sound before you depend on it.
Phone-call ringtones, notification sounds and alarms are distinct settings. If your goal is an incoming-call sound, use our Android ringtone setup guide. For a short audio file, see ringtone length and format.
