Analyzes and adjusts the volume of MP3 files
MP3Gain analyzes and losslessly adjusts mp3 files to a specified target volume. It does not simply do peak amplitude normalization. Instead, it performs statistical analysis to determine how loud the file actually sounds to the human ear.

projectM, a MilkDrop compatible opensource music visualizer
projectM is an OpenGL based advanced music visualization program for Linux, Mac OSX, and Windows. It is backward compatible with all the features of Milkdrop 1.x (and now 2.x), but has many new toys and enhancements.
Finds problems in MP3 files and helps the user to fix many of them using included tools. Looks at both the audio part (VBR info, quality, normalization) and the tags containing track information (ID3.) Also includes a tag editor and a file renamer.
A free multi-track audio editor and recorder
Audacity is no longer at SourceForge. Audacity can be downloaded via AudacityTeam website instead: http://www.audacityteam.org/download/ Audacity is a free, easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. Audacity is free software, developed by a group of volunteers and distributed under the GNU General Public License (GPL). Programs like Audacity are also called open source software, because their source code is available for anyone to study or use. There are thousands of other free and open source programs, including the Firefox web browser, the LibreOffice or Apache OpenOffice office suites and entire Linux-based operating systems such as Ubuntu
Graphical User Interface (GUI) for MP3Gain, VorbisGain and AACGain (enables you to modify the loudness level of mp3,ogg,mp4 files) / Frontend for MP3Gain / Grafische Benutzeroberflaeche fuer MP3Gain, VorbisGain und AACGain
getID3() is a PHP script that extracts useful information (such as ID3 tags, bitrate, playtime, etc.) from MP3s & other multimedia file formats (Ogg, WMA, WMV, ASF, WAV, AVI, AAC, VQF, FLAC, MusePack, Real, QuickTime, Monkey's Audio, MIDI and more).

Virtual Sound Level Meter for analyzing calibrated sound files
This project is the MATLAB development of a virtual sound level meter. The program will read in a calibrated .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. The software implements Fast, Slow, Impulse and LEQ; A, C and Flat Weighting; Ln and Noise Dose analysis; Octave and 1/3 Octave band analysis; high resolution FFT analysis and spectrograms. Band analysis can be made using fast FFT methods or slower, but ANSI standard methods. Source code requires MATLAB + Signal Processing Toolbox. Developed under MATLAB R2010a (but might work with some earlier versions) Executable version does not require MATLAB and runs under Windows XP, Vista, and Windows 7.
AudioSlicer is a Cocoa GUI application that finds all silences in an audio file and allows you to split it into several smaller audio files and to name/tag them properly. For now only MP3 is supported but other formats may come in the future.
Mixxx has moved to http://www.mixxx.org. Please visit our official site for the latest updates, as our SourceForge page is completely out of date.

Multiplatform GUI of MP3Gain which adjusts volume of MP3 files
Graphical user interface front end supporting MP3Gain engine which analyzes and losslessly adjusts MP3 files to a specified target volume. A complete re-creation (made in QT4) of the original MP3Gain GUI, however it can be run on more platforms.
An Interactive Source Separation Editor
In applications such as audio denoising, music transcription, music remixing, and audio-based forensics, it is desirable to decompose a single-channel recording into its respective sources. To perform such tasks, we present a new software tool to perform source separation by painting on time-frequency visualizations of sound. Initial results shows the software can achieve state-of-the-art separation results compared to prior work.
