Ardour Ardour is a professional multitrack/multichannel audio recorder and DAW for GNU/Linux, using ALSA-supported audio interfaces. It supports up to 32 bit samples, 24+ channels at up to 96kHz, full MMC control, a non-destructive, non-linear editor, and LADSPA plugins.

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.

AudioMove 2 'AudioMove' is a GUI-based batch audio file converter/copier program. It converst various audio file formats to WAV or AIFF format (using libsndfile), and do high-quality sample-rate conversion at the same time (using libsamplerate). It supports 8-bit, 16-bit, 24-bit, 32-bit, or floating-point output sample widths. It is multi-threaded for maximum throughput, can handle thousands of files per batch, and does recursive directory scans.

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.
