ALURE is a utility library to help manage common tasks with OpenAL applications. This includes device enumeration and initialization, file loading, and streaming. As of version 1.1, it is X11/MIT licensed, allowing it to be used in open- and closed-source programs, freeware or commercial. The purpose of this library is to provide pre-made functionality that would otherwise be repetitive or difficult to (re)code for various projects and platforms, such as loading a sound file into an OpenAL buffer and streaming an audio file through a buffer queue. Support for different formats is consistant across platforms, so no special checks are needed when loading files, and all formats are handled through the same API. Currently ALURE includes a basic .wav and .aif file reader, and can leverage external libraries such as libSndFile (for extended wave formats and several others), VorbisFile (for Ogg Vorbis), FLAC (for FLAC and Ogg FLAC), and others. External libraries can also be dynamically loaded at run-time, or individually disabled outright at compile time.

OpenAL Soft is a software implementation of the OpenAL 3D audio API and an alternative to the somewhat outdated reference implementation. As stated on the website, OpenAL provides capabilities for playing audio in a virtual 3d environment. Distance attenuation, doppler shift, and directional sound emitters are among the features handled by the API. More advanced effects, including air absorption, low-pass filters, and reverb, are available through the EFX extension. It also facilitates streaming audio, multi-channel buffers, and audio capture.

Userland scaffolding to load M-Audio firmware into supported sound devices upon attachment. Supported devices: * Sonica * Ozone * MobilePre USB (some newer models don't need this port) * Transit Based upon the madfuload package.

mp3lint is a tool to check collections of audio files for various problems. It is highly configurable, allowing you to specify your preferred format for filenames, minimum bitrate, tests to ignore, etc. Formats checked are currently mp3, ogg, wav, flac, au, and m3u playlists. mp3lint is implemented as separate tools (perl modules), each of which implements a set of tests. There are a total of 32 different tests.

mp3plot prints out a plot of the bitrate distribution of a VBR MP3 file (it will also do it for CBR files although it isn't very meaningful).

Library of OpenCORE Framework implementation of Adaptive Multi Rate Narrowband and Wideband speech codec.

The Audio-Scrobbler module provides a Perl and command-line interface to Last.fm's AudioScrobbler - http://www.audioscrobbler.com/.

The PyOgg project provides a set of python modules for the various streaming formats and protocols defined by the Xiph.Org Foundation. For now, it mostly deals with the Ogg bitstream container and the Vorbis audio codec.

A small and flexible console mixer using ncurses.

VisualOn AAC encoder library This library contains an encoder implementation of the Advanced Audio Coding (AAC) audio codec. The library is based on a codec implementation by VisualOn as part of the Stagefright framework from the Google Android project.
