free audio editorQuickly edit any MP3 or AAC file on your Mac. If you need to make a quick edit to a file–like creating a ringtone or cropping a hidden track from a song–Macsome Audio Editor is a great free tool. It’s certainly not the most advanced audio editor on the planet, but it’s perfect for quick jobs.

When it come to audio editing on a Mac, it’s hard to top Garage Band. It’s easy to use, as you can discover in our Garageband manual, but it’s also an overkill for quick edits. You can’t edit a file directly, instead needing to import it to a project which you’ll later need to export.

If you need something simpler, check out Macsome Audio Editor. This free program offers only the simplest audio editing features: cropping, fades and volume control, but sometimes that’s all you need. I’m amazed nothing like this comes with OS X by default.

Using Macsome Audio Editor

The main interface of this program isn’t terribly complicated, as you can see:

From here I can visualize what I’m editing, which is important. I can zoom in and out as I see fit, and I can listen to the recording whenever I want.


I’m a nostalgic nerd, so I’m turning the underground theme from Super Mario Bros into a ringtone. You know the one I’m talking about:

I’ve recorded the file but what I have is way too long; my phone won’t use it as a ringtone. No problem: this song is a simple loop, I really only need on part of it to use this as a ringtone. I select the part of the song I need using my mouse and crop out the rest. I zoom in while doing this, to ensure I only get the parts of the music I want, then listen to make sure again.

Cropping is one of the functions you can easily access from the main toolbar:

These buttons, from left to right:

  • Open a file (duh)
  • Save your file (duh)
  • Set a beginning point while listening
  • Set an end point while listening
  • Removes everything except what is between your beginning and end points
  • Removes only what is between your beginning and end points
  • Increases to volume of audio between your beginning and end points
  • Decreases the volume between your beginning and end points
  • Fades up between your beginning and end points
  • Fades down between your beginning and end points

There is also, at right, an ID3 tag editor. You can even add artwork!

When you’re done you can save the file. There is basic control over the quality and more:

    Their webpage implies that this will do non-destructive MP3 editing, which isn't the case. The MP3 gets re-encoded.

    That being said, it seemed to work for me.
