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.
A high quality MP3 encoder
LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!
A unified display of relevant technical and tag data for A/V files
MediaInfo is a convenient unified display of the most relevant technical and tag data for video and audio files.
The Pure Data (short Pd) project on SourceForge unifies the extensions (or externals) written for the Pure Data Graphical Computer Music System written by Miller Puckette with contributions from many others.
MP3val is a small, high-speed tool for MPEG audio files validation and (optionally) fixing problems. It was primarily designed for verification of MPEG 1 Layer III (MP3) files, but supports also other MPEG versions and layers.
WaveSurfer is an open source tool for sound visualization and manipulation. Typical applications are speech/sound analysis and sound annotation/transcription. WaveSurfer may be extended by plug-ins as well as embedded in other applications.
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 bit-perfect audio editor that doesn't modify samples needlessly
WaveShop is an audio editor for Windows XP/Vista/7/8. Unlike many similar apps, WaveShop is bit-perfect, meaning samples aren't altered unless they need to be. Editing a portion of an audio file only affects that portion; the rest of the file is untouched. Blocks of audio can be cut and pasted without changing their contents at all. This is especially useful for patching a finished master without corrupting its dither.
SPTK is a suite of speech signal processing tools for UNIX environments, e.g., LPC analysis, PARCOR analysis, LSP analysis, PARCOR synthesis filter, LSP synthesis filter, vector quantization techniques, and other extended versions of them.
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
VGMToolbox is a C# based tool to assist VGM collectors and dumpers. It includes tools to extract, optimize, and build VGM formats as well as auditing and exploration utilities. [GBS, KSS, MDX, NSF(E), SID, S98, SPC, VGM, XA, XMA, xSF (PSF/PSF2/etc)]
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).

Automatic audio RMS normalizer & splitter
Fast batch audio processor for automatic loudness adjustment and audio files splitting. The software automatically normalizes a batch of files to a given RMS volume, and can split tracks in several ones by detecting low level ("noise") chunks. It embeds : - a multi-band limiter, - an Automatic Gain Control, - an automated 10 bands equalizer, - a classic 3 bands semi-parametric equalizer, - a noise gate, - a trimming function, - user preset management. Portable version needs VC 2015 RunTime to be installed https://www.microsoft.com/fr-fr/download/details.aspx?id=48145 You use LASTAR for your mobile music library ?

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.
MPC Maid ("MM") is a software editor for the Akai MPC 500, MPC 1000, and MPC 2500. It is Mac, PC, and Linux-compliant and makes the edition of MPC programs files easy. It also features a semi-automatic slicing tool to chop loops into slices.
Windows VU Meter is a standalone application that mimics an old stereo's VU or audio level meters. Please see the project's website at http://windowsvumeter.sourceforge.net/ for all of the program's details and features and download.
9-Octave Chromatic Tuner
Free open source GPL instrument / musical chromatic tuner (like an electronic guitar tuner) for Windows, Windows Mobile, & Pocket PC. Displays name of note played & accurate indication of whether pitch is sharp, flat, or exact (relative to 440Hz A).
Feel the music
Best level of equalization sound, convert your audio format, listen web radio, show music representation with spectrum and VU metter. Set equalization in played music, apply effects. Feel the difference and change your experience to listen music.
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.
