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:
  1. 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)
  2. 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.)
  3. 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.
What does MP3Gain Express not do?
MP3Gain Express omits some features of the original MP3Gain, hence'Express' tacked onto the name.
  1. 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.
  2. Versions of Mac OS X older than 10.6 are not supported.
  3. 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.
Over time, several missing features were added whichmay have made the original intention of the express name no longer necessary.However, the addition of multi-threaded processing made the application fasterthan the Windows front end, so now the express name may imply that it is fast.

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:

  1. 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.
  2. 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.
After I reached the point where it was partially working, it satuntouched for a few months. By the time I eventually came back to it,Bery had updated his version with Lion support. That version was alsoavailable for a number of years, but eventually disappeared from theinternet after its website went down. This port now has the missingfeatures and should be useful for people who formerly used that one.Disclaimer:I have not actually used his port, so my comparisons are based on the informationon his website.
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.
Who else contributed to this port?
The Spanish translation was provided by Emilio Pérez Egido.
The Greek translation was provided by George Leventidis.
The German translation was provided by Hans-Juergen Merkel.
The Czech translation was provided by GVG.
The icons used in version 2.1 and later were created by George Leventidis.
There were also many users who emailed me with feedback and bug reports.
Where can I get the source code, report bugs, or request features?
There is a project on GitHub for MP3Gain Express where you can check out the current development code for the application, submit your own changes, bug reports, or feature requests. You can find it at https://github.com/Sappharad/mp3gainOSX/.

aacgain is a modification to Glen Sawyer's excellent mp3gain program. It supports AAC (mp4/m4a/QuickTime) audio files in addtion to mp3 files. If you are not familiar with mp3gain, stop reading this, and go to http://mp3gain.sourceforge.net.

aacgain normalizes the volume of digital music files using the Replay Gain algorithm. It works by modifying the global_gain fields in the aac samples. Free-form metadata tags are added to the file to save undo information, making the normalization process reversable.

aacgain uses the same command-line user interface as mp3gain, and is compatible with the mp3gain Visual Basic GUI.

It also integrates with iTunes using my iGain GUI.

BACK UP YOUR MUSIC FILES BEFORE USING AACGAIN! UNLIKE MP3GAIN, AACGAIN IS NOT COMPLETELY REVERSABLE. THE UNDO OPTION IS INTENDED TO RESTORE A MUSIC FILE TO BE FUNCTIONALLY EQUIVALENT TO ITS ORIGINAL STATE, BUT IT WILL NOT BE BIT-FOR-BIT IDENTICAL TO THE ORIGINAL FILE. IT IS POSSIBLE FOR APPLE TO CHANGE THE ITUNES MUSIC FILE FORMAT IN WAYS THAT ARE INCOMPATIBLE WITH AACGAIN, RESULTING TO CORRUPTED MUSIC FILES THAT CANNOT BE RESTORED TO THEIR ORIGINAL STATE. I AM NOT RESPONSIBLE FOR DAMAGED FILES.

aacgain was implemented using

  • mp4v2 to parse mp4 files, and to read and write metadata, and
  • FAAD2 to decode the audio samples.

aacgain is released under the GPL V2 license. I distribute AACGain in source code form only

  • to avoid any MPEG royalty issues, and
  • to ensure that users have the knowledge to fix whatever bugs they find :-)

Source code can be found in the mp3gain cvs repository on Sourceforge. The module name is aacgain.

A compiled binary for Microsoft Windows® is hosted at rarewares.org.

Pre-built Unix packages are available for Arch, Debian, Mac OS X, Slackware, and Ubuntu.

What's new in Version 1.9

  • Fixed a bug in mp4v2 which caused iTunes music video files to fail with 'not a valid mp4/m4a file' error.
  • Gives a more meaningful error message when attempting to process Apple Lossless files.
  • Built with updated mp4v2 from Google Code, which should build error-free on modern Windows, Mac and Linux systems.
  • Built with updated faad2 code, which should build error-free on modern Windows, Mac and Linux systems.
  • Built with latest mp3gain version 1.5.2 source checked into CVS, which includes id3v2 tag support.
  • MSVC++ solution and project files have been converted to Visual C++ 2010 Express Edition.

Version 1.8 fixed the following issues:

  • Built with mpeg4ip/mp4v2 version 1.6.1. Aacgain 1.7.1 was built with
    version 1.5.20. Mp4v2 version 1.6.1 corrects problems that corrupted
    video files containing Quicktime chapter markers.
  • Built with latest mp3gain version 1.4.7 sources checked into CVS.
    The mp3gain changes made since 1.7.1 support sample rates up to 96000.
    Previous versions had a maxmimum sample rate of 48000.
  • Ignores faad2 'scalefactor out of range' errors. These errors resulted
    in 'invalid file format' errors on apparently good files.

Version 1.7.1 fixed the following issue:

  • MSVC++ solution and project files have been converted to Visual
    C++ 2005 Express Edition. Other than the version number, no other
    source code changes have been made.

Version 1.7 fixed the following issue:

  • If the total length of the directory plus file name path exceeded 64 bytes, memory corruption would occur. This has been corrected.

Version 1.6 fixed the following issue:

  • Files with a 'cprt' (copyright) tag are now processed correctly. Previous versions of aacgain corrupted the metadata of files with a copyright tag.
  • AACGain now works on video or other files where the first audio track has a track number of other than 1. Previous versions required the audio track to have a number of 1. AACGain will still only process the first audio track found on a file. Thanks to Arthur Yarwood at Sony Computer Entertainment Europe for this fix.

Version 1.5 fixed the following issue:

  • Running AACGain on Apple lossless or other unsupported file format resulted in a crash with an unhandled exception.

Version 1.4 fixed the following issues:

  • Temporary files are created in the same directory as the input file. Formerly they were created in the same directory that the program was run in. This solves a problem only seen on Unix systems where the temporary file could not be renamed back to the original input filename, if the input file was located on a different filesystem from where the program was run. Windows users are unaffected by this problem and can continue to use 1.3.

Version 1.3 fixed the following issues:

  • Always uses the /t (use temp file) option, even if it is not specified on the command line. This resolves issues where processed files would not play on the iPod Shuffle.
  • Preserves original values of MP4 properties bufferSizeDB, maxBitrate and avgBitrate. Without this change, mpeg4ip/mp4vs was recalulating the actual values of these parameters. This caused bitrate as displayed by iTunes to change slightly, i.e. songs ripped at 320KB would display as 319KB.
  • Incorporates recent changes to mp3gain which prevent crashes when working with 48KB files on Linux.
  • Source code directory structure was reorganized to be compatible with mp3gain CVS on sourceforge. Thanks to Glen Sawyer, the AACGain source code is now hosted on sourceforge's CVS repository as part of the mp3gain project.

Version 1.2 fixed the following issues:

  • Compatibility issue with MP3GainGUI version 1.2.5 or 1.3.4.
  • All temporary files created are erased.

Version 1.1 fixed the following issues:

  • Multi-channel and mono files now work.
  • Fixes compatibility issues with MP3GainGUI: the /o option always outputs Album gain.
  • The /f option is ignored for AAC files. If a file starts with a 'ftyp' atom, it is assumed to be AAC, even if /f was specified. This prevents the /f option from corrupting valid AAC files.
  • Uses portable versions of all library functions, and has been successfully compiled under Linux. Thanks to Prakash Punoor for his help with this.

Thanks to Glen Sawyer, source code for AACGain is hosted in the sourceforge cvs repository as part of the mp3gain project, in the aacgain module.

As of aacgain version 1.9, I have access to Linux and Mac systems, and I am now supporting the Linux build environment originally developed by Prakash Punnoor. See the source code 'linux' subdirectory for details. The file 'unix_build_system.tar.bz2' remains in the CVS repository for historical reasons, but is not being maintained, and is not compatible with the current source code.
