About the Audio Cutter & MP3 Trimmer
The Audio Cutter trims songs, voice notes, podcasts and sound effects to exactly the part you need. A waveform shows the loudness of the whole file, so it is easy to spot silence, speech and the chorus of a song. Drag the start and end sliders, listen to your selection and export it.
Add a smooth fade in and fade out to avoid abrupt starts and endings, which is especially nice for ringtones (iPhone ringtones must be 40 seconds or shorter, Android ringtones can be any length). Export as MP3 for small files or WAV for further editing. The tool can also cut the audio track of video files. Everything is processed on your device.
Making a ringtone and other quick edits
A ringtone in four steps
- Open the song and find the chorus on the waveform. Loud parts look taller.
- Drag the start and end to select 20–30 seconds.
- Add a 1-second fade in and a 2-second fade out, so it does not start or stop abruptly.
- Export as MP3. On Android, set it in Settings → Sound → Ringtone. On iPhone, ringtones must be turned into M4R with GarageBand or iTunes and be 40 seconds or shorter.
Other uses
- Remove silence at the beginning and end of a voice recording.
- Cut one answer out of a long interview to share it.
- Make a short intro or sound effect for a video or podcast.
Use Play selection to listen before exporting. Choose WAV if you will edit the clip further in another program, since it keeps the decoded quality exactly.

Frequently asked questions
How do I make a ringtone?
Select a 20–30 second part of a song, add a short fade in and fade out, and export as MP3. On iPhone, ringtones must be converted to M4R with GarageBand or iTunes.
Does cutting reduce quality?
Exporting to WAV keeps the decoded quality exactly. MP3 export uses 192 kbps, which sounds excellent for most music.
Are my files uploaded?
