You don't need much to set an MP3 file as a ringtone or notification sound. Technically, the only requirements are an Android phone and an MP3 file. You might need an internet connection, depending on whether you have the MP3 stored locally or not. You might also need a PC and extra software for trimming the audio file.

Trimming the MP3 file

You don't really want the whole song to be played as a ringtone. Well, you might, and you can skip this step if you do. That won't always be the case, though. Most times, you'll want to hear only a specific part of a song or MP3 audio. There's a plethora of software you can use to trim your audio files, such as Adobe Audition, Reaper, and Pro Tools. We'll only touch on a couple of options to make things simpler, though; one for PC and one for Android.

How to trim an MP3 file with Audacity:

Download, install, and launch Audacity. It's available for Windows, macOS, and Linux.
Go toFile > Import > Audio.
Select the MP3 you want to find.
Use the selection tool and cursor to highlight the audio part you want to keep as your ringtone.
Once a section has been selected, you can press the space bar to play only that part and make sure you like it.
Now clickEdit > Remove Special > Trim Audio.
Only the section you selected will remain.
PressF5 to activate theTime Shift Tool and drag your audio to the beginning of the timeline.
I would also advise using the Fade In and Fade Out in the beginning and end. These options can be accessed by going to the Effect menu.
Now go toFile > Export and select MP3.
Move the file to your smartphone.

How to trim an MP3 file with Music Editor:

Download, install, and launch Music Editor from the Google Play Store.
Tap on theTrim Audio option.
Select the song you want to turn into a phone ringtone.
Drag the sliders to select the part of the song you want to keep as a ringtone. The green one is the beginning and the red one the end.
You can use the media controls at the bottom to get a preview.
Hit thefloppy disk icon on the top-right.
Select a name for the new file.
HitOK.
