A free multi-track audio editor and recorder
Audacity is a free, easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. The interface is translated into many languages. The version currently hosted here is 2.1.0 (March 2015). More recent versions than this are available from http://www.audacityteam.org/download/ . 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
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.
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.
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.
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.
Rakarrack is a stereo digital effects processor for Linux with jack support. Standard line-up of nearly 40 effects modules include Equalizers, Reverbs, Echo, Flange, Chorus, Distortions, WahWah, Vocoder, and other filters and processing modules.
Linux Studio Plugins Project
LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. Also standalone plugins for JACK are provided since version 1.0.8. The basic idea is to fill the lack of good and useful plugins under the GNU/Linux platform. After some contributions to other open source projects the decision was made to implement separate and independent plugin distribution.
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.
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).
DRC generates digital room correction FIR filters to be used within HiFi systems in conjunction with real time convolution engines like BruteFIR.
This application can help you quickly identify the name of any song.
My Music Recognition uses a powerful audio recognition engine in order to help you get the name of the song you are listening to. It can capture sound from radio streams, the installed music player or any other source and display the name of the song in seconds.
Sonic Visualiser is an application for inspecting and analysing the contents of music audio files. It combines powerful waveform and spectral visualisation tools with automated feature extraction plugins and annotation capabilities.
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, - a 3 bands semi-parametric equalizer, - a noise gate, - a trimming function, - user preset management. Portable version needs VC 2013 RunTime to be installed https://www.microsoft.com/fr-fr/download/details.aspx?id=40784 You use LASTAR for your mobile music library ?

AUDio MEasurement System - multi-platfrom system for audio measurement through sound card in the PC. Incorporates Generator, Oscilloscope, FFT, Sweep frequency characteristic. Now it can be compiled and works under MSWindows and Linux.
IMMS is an intelligent playlist plug-in for XMMS that tracks your listening patterns and dynamically adapts to your taste. It is incredibly unobtrusive and easy to use as it requires no direct user interaction.
VLevel is a dynamic compressor which amplifies the quiet parts of music. It uses a look-ahead buffer, so the changes are gradual and the audio never clips. It is a command line filter and a LADSPA plugin, so it works with XMMS.
Vamp is an audio processing plugin system for plugins that extract descriptive information from audio data.
Yet Another Audio Feature Extractor is a toolbox for audio analysis. Easy to use and efficient at extracting a large number of audio features simultaneously. WAV and MP3 files supported, or embedding in C++, Python or Matlab applications.
Sound Editor for KDE
Kwave is a sound editor for the KDE environment. It is written with KDE/QT and is extendable through a powerful plugin interface. For the moment it supports .wav files and many other formats, recording/playback via PulseAudio, Qt Multimedia, OSS and ALSA and some simple effects
A convolution plug-in for Windows Media Player, DirectShow/DX (for use with ZoomPlayer Pro, Media Player Classic, etc) and VST. Allows cross-feeding of channels. For room correction, bass management, cross-overs, equalization, etc.
