Editors' review

MP3 Trimmer for Mac allows you to make substantial edits to an MP3 file without the need for re-encoding, all in a single, easy-to-use interface. The result is a useful app for anyone that frequently edits, cuts, or snips sections from MP3 tracks for video or audio production. While the interface is minimal, the app runs smoothly and provides a full trial experience. It offers numerous tools that are easily accessible and we found it to be fast and effective.

After installation of the app, you'll be forced to wait for a few seconds for it to load to access the trial version, but there are few limitations on its operation once it is up. Load an MP3 file into the app and you can start trimming by setting the in-point, the out-point, the playback speed and volume, and much more. The core functions are on the screen along with all of the basic audio metadata from the MP3 file, and you can make small adjustments to things like audio fading, gain, and silence, but there are also more functions in the menu bar to choose from if you want to further adjust your MP3 file. Everything worked quickly and saving your editing MP3 file is very easy, not requiring any additional encoding before export.

If you want a streamlined, clean interface for basic edits to your MP3 files, download the trial for MP3 Trimmer. It offers a range of functions that will allow you to make edits to your MP3 files on the fly. This is a useful app that even at the full upgrade price is worth checking out for those that frequently trim and cut MP3 files for other uses.

Editors' note: This is a review of the trial version of MP3 Trimmer for Mac 2.9.6.

    "Ho...Hummm.. Have seen better ones."

    Version: MP3 Trimmer 2.9.6


    Editing is easy and the interface is pretty good. Delivers but it comes with a catch.


    Edited files can only be saved in 128kbps. Come on guys, we live in 2014! We need higher bitrates than that! And your support sucks.

    "Great utility for voice editing"

    October 01, 2012   |   By Spoffo

    Version: MP3 Trimmer 2.9.6


    Precise control, very convenient ability to test trims. Detailed, pro-type interface with full information. Does joins too. Uses standard editing keyboard shortcuts. One-step workflow for web audio clips while maintaining compact file size (see comments)


    none for me


    I use it for editing voice tracks and occasional music clips for websites, so the 128k bitrate limit mentioned in other reviews is no issue for me. Other editing solutions for this that I've tried, like Quicktime Pro and MPEG Streamclip, have a giant disadvantage: After you've made your trims and cuts, you have to save them as .mov files (Probably because of licensing issues with the company that owns MP3.)
    Many embedded webpage audio players are very fussy about formats they can play back. They will play back .mov files in a browser on a mac, but on windows they will often freeze on .mov and will play only clean mp3 files.
    As a result, you have an added step in your workflow: converting the edited .mov file back into mp3, and here's the big problem: all the tools I've found for converting .mov to .mp3 produce a <b>much bigger file </b> like around 2.5 to 3 times bigger. So a 20 minute audio clip that may have been 7 mb in the original mp3 recording, and maybe a 6 mb .mov after trims and cuts, becomes a 16 mb pig when converted back to mp3. And that can make web performance over slow dsl or 3G terribly sluggish.
    This is the only product I've found that gets around this problem. It gives a streamlined, one-step workflow with optimized results.

    "OK if you like all your music encoded at 128 Kbps."

    July 23, 2012   |   By JonCalgary

    Version: MP3 Trimmer 2.9.6


    Simple interface. Does what it promises, to a point.


    Apparently only outputs to 128 kilobytes per second. I have most of my music encoded much higher than that, or VBR hovering around 200. The software will import it to work with it at higher bit rates, but only saves at 128. This is a huge omission, as we all know 128 is not the best quality (160 is the bare minimum for reasonable quality), and most other MP3 apps output to varying bit rates and even VBR. Therefore, do not delete or overwrite your original files. Also, "keep ID3 tag" selection is turned off by default for some odd reason. There are only barebones help files, especially for setting preferences; doesn't really tell what things do. And, apparently, support seems to be missing in action according to other review sites.


    OK if you need stuff to trim and have a MP3 player without much space. However, it will not fix your original files and maintain their higher quality. If you want more control in editing (and saving to the original bit rate), seek out Fission. Not as idiot-proof, but audiophiles will be happier.
