Cut and join portions of MP3 songs.

Overview

MP3 Trimmer lets you cut off portions of MP3 files, fast and easy, without re-encoding. Normally, you would need to convert the MP3 file to an editable audio format, like AIFF or Wave, edit the file, save it and then re-encode to MP3 again.

Features:
  • Edit your MP3’s fast and easy - no more converting between audioformats
  • 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
  • All operations are done at bit level, which means no quality loss at all
  • Slick and intuitive interface - appreciated by people all over the world
  • Try it out for FREE as long as you want before you decide to buy

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.

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

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.

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.

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.

In May 2015 I wrote to DeepNiner:
when using IN-point audition + or - you don’t see a result.
You have to leave this window; then you see a change when you click on Try.
Could you repair that please?
He promised to repair that but in spite of many reminders nothing till now.

From DeepNiner's FAQ

"Q: I have written to you, but got no response...
A: Unlike big software companies, I develop MP3 Trimmer on my spare time. I have a regular fulltime job and a family as well. Be patient, or in urgent matters, send me a reminder about your email. "

I bought this about three weeks ago and I agree simple and beautiful. Exactly what I was looking for. But the day you posted this, and I do remember well it was my birthday. :lol: It stopped working. When I try to open it just bounces in the dock . Have sent emails , no response :( I want it desperately!! I have spent hours trying to find something that works the way this does. If anyone has any tips I would love them. Have reloaded multiple times.

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.
