MP3 Trimmer is much more than its name suggests. This Mac program is also capable of joining, analyzing, and repairing any MP3 file within your local directories as well as trimming multiple songs at the same time, using the same output configurations.
To be honest, I'm not too fond of the application's interface. To me, it looks more like a Windows app and doesn't offer you the simplicity you often see within OS X programs (I tested similar Mac apps which offered much more intuitive main windows).
Nonetheless, the utility supports drag-and-drop actions, comes with an integrated batch processing tool, and immediately offers the quality results you need. What's more, you have access to an MP3 analyzing tool which shows you vital data about the audio file and detects errors.
Another thing I like about this Mac application is the fact that it comes with an MP3 repairing tool which comes in handy if the analyzing utility finds errors within the audio file.
All in all, MP3 Trimmer is a feature-rich and capable Mac program. The app immediately offers you the quality results you need, allows you to pre-listen the output files before exporting them to your local drives, and comes with a reasonable price.
