- Trim the desired portion, add fade-in / fade-out, change gain and even add silence
- Batch-edit in order to automate operations with large amounts of files
- Add and edit ID3 information in your MP3 files
- Split MP3 files or join several files together
- Built-in tools to help you analyze and repair broken MP3 files

Version: 3.3
Sadly no longer works with 10.14.6 Mojave. Saved files are not trimmed.

Version: 3.3
I've loved this app for many years, however, because it has never been updated to support 64-bit processors, it will not run on the new Mac OS Catalina (version 10.15), and therefore I can no longer use it on my MacBook Pro that I upgraded to the beta. I can at least still run it on my old 2009 iMac (which Apple cut off OS upgrades for after High Sierra) if needed, although I frankly don't really use MP3 Trimmer anymore since Apple took away the ability to create your own ringtones in IOS, so this post is mainly just an FYI to others reading these comments.

MP3 Trimmer is still indispensible. I use it to combine Audiobooks into longer chapters as well as trimming out snippets from longer recordings.
MP3 Trimmer on my Mac is v3.3 not the v3.0 currently shown here.

Version: 3.0
This seem to be working in OS X El Capitan 10.11 at least and does seem highly useful for some mp3 editing. Sadly there is no automated function for removing the initial silence in mp3 encoded files (which might be hard to achieve), no zooming to speak of, no reverted polarity, no paste mixing and so on., Off little use to me unfortunately.
Nice to see it's still around.

Version: 2.9.6
It's a brilliant app unfortunately totally unsupported. No answers to repeated emails over weeks. Registered and got 1 day out of it. Can't give it stares because I can't use it.

v2.9.6 Caused some freezing on Lion requiring Force Quit. No data was lost however. Worth the price

MP3 Trimmer has many features, it's very easy to use, it is excellent value, and, it's as stable as a rock.
MP3 Trimmer joins multiple MP3 files.
AHP2 recorded a 4.3 hour event, but it broke the recording into two parts.
MP3 Trimmer has "MP3 Joiner". Open MP3 Trimmer, select "Tools">"MP3 Joiner", add files, check the order, add as much or as little info as desired (for the output file), select "Select Target Folder" and name, and, a few moments later, you have a single (joined) MP3!
If you do any audio editing, MP3 Trimmer is a must have.

Version: 2.9.1
When I used this great app for the first time, it always showed CRC errors after saving a trimmed MP3 so that I thought the file is not saved at all. But it is saved! And functioning! You can ignore the CRC errors. But: For the next version I wish some more words in the error message saying that this can be ignored.

Version: 2.8.8
Love this app. Works great with all the textbook audio I have to manage.
The recent version 2.8.8 is shown as version 2.8.9 in the Get Info window and the About MP3 Trimmer window.

Version: 2.8.56
I must apologise for the inaccuracy in my review (see below). MP3 Trimmer DOES have switchable fade algorithms (I didn't realise the icons are switches).
Awesome. I've been editing out the dialogue and announcements from the music podcasts I subscribe to and the app is perfect. Great drag n drop too...
Nov 8 2008
Version: 2.8.5
This is a very efficient app for top and tailing mp3s and adding auto-fades. It's entirely intuitive, quick in operation and a great solution. Highly recommended.
As a feature request I'd like to see some switchable auto-fade algorithms. The algorithm in use is a bit linear, and not very natural (ie. the tail is too long) at short settings. That addition would make this app perfect.

After trying a few mp3 joiners, this one is the best. Slick interface, works as advertised.
Feb 20 2008
Version: 2.8
I've used this wonderful app since almost it first hit the Mac's desktop.
It is the best utility for cropping MP3s and joining multiple MP3s into one file. Despite its quirks it is still the fastest and most straight forward method of doing this.
Fission has some good features because it is more visual and handles other audio formats, but MP3 Trimmer seems less sluggish and certainly less confusing. You can never be sure where a drag and drop ends up in Fission and once it is in there is no clue as to the original file.
A few draw backs. The Joiner scrambles the file order when dragged from List view, you need to drag from column view. Reordering within join is clumsy. The joiner also hides the file name whilst joining and needs to be closed and reopened for every join. There is really no way to batch process. files.

Version: 2.7.5
Seriously underrated app. There's nothing else like it for the Mac. I've managed to rescue many garbled MP3 downloads using the repair options. Fantastic!
Mar 10 2006
Version: 2.6
I love this program. It's perfect for cutting tracks as ringtones.
Feb 26 2006
Version: 2.6
Trimmer 2.6 is another step up for this great app.
I used it to edit my streaming radio recordings. It is a good fit in ease-of-use, interface design, and a perfect companion to my 4GB nano.

I Like It!
Does it's thing nicely, though i've found more use for it's joining capability than trimming.
