MP3GainExpress is a port of MP3Gain and AACGain to macOS. It allows you toanalyze or apply volume gain to a list of MP3 or AAC files. Anyone who has usedthe Windows UI for MP3Gain should find this one familiar, as itwas designed to look similar to that version.
It's easy to use. Simply select the files you want to increase ordecrease the volume of, enter the desired loudness, and click ApplyGain to update your files.
Disclaimer: If you are using this program for the first time, please remember to back up your files before trying to modify them with MP3Gain. While the application should work fine for most users, differences between machines could result in problems that only affect a small number of people.

Questions and Answers
What is MP3Gain?MP3Gain is a tool to increase or decrease the volume of MP3 fileswithout re-encoding them. This is useful when you have a lot of musicat different volumes, you can use this tool to make everything the samevolume so that you don't need to adjust the volume on your MP3 playerwhen listening to your music on shuffle.
What does MP3Gain Express do?
This version of MP3Gain does three things. It can:
- Analyze MP3 files and write the volume information to a tagwithout changing the audio data itself. This is useful if you have aplayer that supports 'ReplayGain' tags. (Not iTunes or iPods, so mostlyuseless on Mac OS X)
- Apply Gain to MP3 files. This updates the audio data in the filesto apply the new volume directly to them. This is done without re-encodingthe file, so there usually is no loss in audio quality compared tooriginal data. (I assume that if you make the file loud enough to start'clipping' that this would count as quality loss. The loudness ofdigital audio can be represented within a range of values, and once yougo above the maximum any points above the maximum can only berepresented as the maximum itself. If the 'Clipping' column shows Yesthen this situation is occurring. In some cases, depending on how loudyou go, you may not notice it. You can click the 'Prevent Clipping' checkbox to automatically use a lower value if clipping would occur.)
- Undo changes applied to MP3 files, returning them to their original volume. This will only work if the file has previously had gain applied to it, and undo has not been performed on the file. The undo feature cannot remove file corruption in files that were accidentally damaged by the program.
MP3Gain Express omits some features of the original MP3Gain, hence'Express' tacked onto the name.
- MP3Gain Express does not back up your files for you. As with anyapplication, there is a chance something could go wrong. If you'venever used the tool before, I suggest backing up your files first tomake sure it works as you intended.
- Versions of Mac OS X older than 10.6 are not supported.
- MP3Gain is for audio files only.The .mp4 extension allowed because some AAC files use that extension, butplease do not use it for processing video files. It will not work.
Why port MP3Gain to Mac again, eventhough a port already existed?
This port was made to fulfill one need that I had. I wanted to increasethe volume of a few tracks I had that were too quiet. I didn't need anyof the other features of the program, so they originally were not available in this port. Over time, more features were added as a result of user requests.I started this port a few weeks before Mac OS X 10.7 Lion wasreleased, and Bery Rinaldo's port had not been updated in over 3 yearsso I assumed it was dead. It also wasn't compatible with Snow Leopardat the time.
I decided to do my own port for two reasons:
- The existing port was a front-end written in AppleScript. Anyonefamiliar with my previous work (MultiPatch for example) might be awarethat I prefer to call code natively and not use an external tool to dothe work. I felt that this could benefit from the increased flexibilityof a native application. This approach was eventually changed in version2.0 in order to implement multi-threaded processing, but the existingnative UI has been retained and the application should behave as it didwhen MP3Gain was integrated internally.
- The existing port was bundled with PPC binary at that time, whichwould not work on Mac OS X Lion. My intention was to release the port aroundthe time Lion came out in order to fill that gap.
Is there a build of the command-line version of MP3Gain available on macOS for power users?
Yes. I am now providing a command-line build of MP3Gain with AACGain support. This is the command-line version of AACGain 2.0.0 built for macOS 10.9 or later.It is based on the 2.0.0 fork from Github, refer to the source repository for exact revision used.You can download it here.Will this port be actively maintainedand updated?
Probably not. MP3Gain itself isn't updated often anymore (Why would itbe? It already does what it was intended to do) and I primarily wrotethis for myself to use once every few years. If this program ever breaks in afuture version of macOS, I will probably update it just so that there'salways a working port available.
What is the license?
MP3Gain is LGPL. This port is also LGPL. You can probably find more information about that license on Wikipedia.

Mp3gain Mac Download Free Music
Here's a list of what you'll find at the SourceForge download page for MP3Gain.
There are two Mac ports that I know of: MacMP3Gain, and MP3Gain Express.
Mp3gain For Windows 10
| MP3Gain-Windows (Stable) | |
|---|---|
| mp3gain-win-1_2_5.zip | Normal MP3Gain, but with no installer |
| If you ever download a newer version of MP3Gain after doing a Full install, you will only need the Normal version. | |
| mp3gain-win-gui-1_2_5-src.zip | Visual Basic source files used to create the MP3Gain GUI. The GUI is just a front end for the command-line program mp3gain.exe, so if you want to completely re-compile MP3Gain from scratch, then you'll also need the mp3gain-1_5_2_r2-src.zip file. |
| MP3Gain-Windows (Beta) | |
| mp3gain-win-full-1_3_4.exe | Exactly the same as the Normal install, but also includes the Microsoft Visual Basic run-time files. The VB run-time files only need to be installed on a computer once, so they might already be in your Windows folder. If you're not sure, then go ahead and download this Full version. Or if you want to save some download time, then try the Normal install first. If you ever download a newer version of MP3Gain after doing a Full install, you will only need the Normal version. |
| mp3gain-win-gui-1_3_4-src.zip | Visual Basic source files used to create the MP3Gain GUI. The GUI is just a front end for the command-line program mp3gain.exe, so if you want to completely re-compile MP3Gain from scratch, then you'll also need the mp3gain-1_5_2_r2-src.zip file. |
| mp3gain (command-line back end) | |
| mp3gain-dos-1_5_2.zip | Command-line only version of mp3gain. If you download any of the Windows MP3Gain files above, this file is included. |
