Audacity Audacity is a cross-platform multitrack audio editor that lets you record sounds directly or import Ogg, WAV, AIFF, AU, IRCAM, or MP3 files. It features a few simple effects, all of the editing features you should need, and unlimited undo. The GUI is built with wxWidgets and the audio I/O currently uses PortAudio.

Audio-Convert audio convert is a script that converts between WAV, Ogg, MP3, MPC, FLAC, APE, and WMA files. It has an easy-to-use interface that makes it possible to fill in the tags for a few formats and choose the quality of compression. The script was initially designed for the Nautilus file browser and can be easily installed into Nautilus by copying it to the nautilus-scripts directory. You can then right-click on files and choose "audio-convert" from the "scripts" menu. The script is also known to work on rox or directly from a shell.

Delvj DelVj is a tool that provides real-time 3D composition and algorithmic video composition in which the computer composes 3D forms as indicated by the user as a virtual extension of the users mind. It can be given indications for the objects, videos, and effects, and the computer can do the rest. It features a GTK+ interface that runs puredata in the background, controls xmms, and allows tweaking of all patch parameters, recording of videos, and streaming to an Icecast server.

Dirogg dirogg is a script to migrate your entire music collection to the Ogg Vorbis format. It's a recursive script, meaning that you run it from the top level of your music directories, and it will automatically recurse and convert all MP3 files to Ogg.

Ecasound Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package.

FLAC The FLAC project consists of:

• the stream format
• reference encoders and decoders in library form
• flac, a command-line program to encode and decode FLAC files
• metaflac, a command-line metadata editor for FLAC files
• input plugins for various music players

FLAC has recently joined the Xiph project, which produces other free codecs such as speex and Ogg Vorbis.

Flac-jacket 'flac-jacket' uses raw audio files (raw files are created from data streams) as the source. Based on the filename format, it first creates lossless audio files, using FLAC, and optionally removes the source files if conversion was successful. It then creates a new html page with links to all new and existing .flac files. The html page is regenerated each run, so the listing is somewhat dynamic: you needn't edit the html page just because you removed or renamed a FLAC audio file or altered an artist directory.

GNU Songanizer Songanizer is a script to organize a directory containing Ogg and MP3 files. The script accepts a list of directories in which the real Ogg and MP3 files reside. It then reads information like author, album, and genre from the files' ID3 tags and creates parallel directory structures which just contain symbolic links real files. The goal is to create virtual directory structures which give different views of the data without having redundant copies of the files themselves.

Gnusound 'GNUsound' is a sound editor for Linux/x86. It supports multiple tracks, multiple outputs, and 8, 16, or 24/32 bit samples. It can read a number of audio formats through libaudiofile, and saves them as WAV files. It also supports many high-quality audio effects through the LADSPA plugin architecture (see http://www.ladspa.org).

Jokosher Jokosher is a simple and poweful multi-track studio. Jokosher provides a complete application for recording, editing, mixing and exporting audio, and has been specifically designed with usability in mind. The developers behind Jokosher have re-thought audio production at every level, and created something devilishly simple to use.

• Jokosher offers a strong featureset:
• Ease Of Use - Easy to use interface, designed from the ground up. Jokosher uses concepts and language familiar to musicians, and is a breeze to use.
• Editing - Simple editing with splitting, trimming and moving tools. Mixing Multi-track volume mixing with VU sliders.
• Audio - Import audio (Ogg Vorbis, MP3, FLAC, WAV and anything else supported by GStreamer) into your projects.
• Instruments - A range of instruments can be added to a project, and instruments can be renamed. Instruments can also be muted and soloed easily.
• Audio - Export to MP3, Ogg Vorbis, FLAC, WAV and anything else GStreamer supports.

Kamix 'kamix' is a mixer for KDE and ALSA, with more features than kmix (or at least with more than kmix had when kamix was started). It supports channel splitting, levels storing/restoring, sync with external ALSA events, correct handling of "enumerated" elements, and selective item hiding/showing.

Kwave 'Kwave' is a 24-bit sound editor that allows simple operations, such as cut, copy, and paste. Some more effect functions with little complexity (Simple Filtering, Delay) are also implemented. More sophisticated analysis functions (spectrograms, sonagrams, pitch determination) are underway or partially done.

MhWaveEdit mhWaveEdit is a program for playing, editing, and recording sound files. It supports .wav files and a few other formats. It can edit both large and small files, and has support for 8/16/24/32-bit signed and unsigned sample formats.

Music Library 'Music Library' is a music-on-demand system for phpGroupware. It searches recursively through a directory full of files for audio formats you specify and dumps their artist, album, and track names into a database. You can then browse, search, or listen over HTTP. It features custom playlists and comes with an MP3 renaming script to make administration easier.

Psychosynth The Psychosynth project aims to create an interactive modular soft-synth inspired by the ideas of the Reactable. We will try to provide a clean object oriented API to allow the creation of new innovative interfaces for the synthetizer and a 3D simulator of a Reactable-alike device with support for collaborative music creation over the internet. Our main goal is to create a free software alternative to allow newbies, developers and professionals explore new ways of making music. It is also important to build a comunity to ease the comunication between we, software devolopers, and electronic music makers, who can provide insightfull ideas on how to turn new experimental features into usefull and creative tools.

Schism Tracker Schism Tracker is a tracked music editor that aims to match the look and feel of Impulse Tracker as closely as possible. The player code is based on the Modplug library, so it supports a wide variety of module formats.

Secret Rabbit Code Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter for audio. One example of where such a thing would be useful is converting audio from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT players. SRC is capable of arbitrary and time varying conversions; from downsampling by a factor of 256 to upsampling by the same factor. Arbitrary in this case means that the ratio of input and output sample rates can be an irrational number. The conversion ratio can also vary with time for speeding up and slowing down effects.

Simple Multitrack Simple Multitrack is a set of programs that allow the simultaneous recording of an audio track while listening to a monitor mix of other tracks. It is software for the command line.

SndBite 'SndBite' is an audio editor designed for breaking large recordings into smaller components with great efficiency. Its principal intended application is in linguistic research where it is often desirable to put each word or sentence into a separate file before further processing. Features include multiple simultaneous views of the waveform at different resolutions, the ability to position window edges at transitions between sound and silence, automated setting of cut points at zero-crossings, automatic filename generation easily controlled by the user, and optional automatic playback on window motion.

Wavbreaker This application's purpose in life is to take a wave file and break it up into multiple wave files. It makes a clean break at the correct position to burn the files to an audio cd without any dead air between the tracks. It will only read wave files, so use an appropriate tool to convert ogg, mp3, etc. files and then break them up.
