The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
MP3 STATION is a LIRC-aware, plain-text tool set for managing MP3 playback in a car or home with as little user interaction as possible. It can restart the last playlist at the last played track/frame, transparently load directories, transparently recompile playlists, and keep a repository of all the playlists. It also has two simple clients for communicating with cm3s (a curses console client and a very basic one on a parallel port). All programs run under a non-privileged user account.
SDL_sound is a library that handles the decoding of several popular sound file formats such as .WAV and .MP3. Designed to make the task of sound playback easier, SDL_sound accepts files or other input through an abstraction layer and returns the decoded waveform. SDL_sound can decode a whole sound file and hand back a single pointer to the waveform, or SDL_sound can process sound data in programmer-specified blocks when resource constraints are a concern. SDL_sound can also handle sample rate, audio format, and channel conversion on-the-fly.
XO Wave is a digital audio workstation designed to meet the needs of audio and video professionals, with a focus on CD mastering and audio for video work. XO Wave provides professional-grade capabilities for manipulating audio, with a familiar and elegant interface. It supports direct recording from any Core Audio device (ALSA/Jack/OSS on Linux), importing and exporting files in a variety of formats (including songs from iTunes playlists), CD burning, multi-track editing, support for many Audio Units, and QuickTime synchronization and export.
Mp3blaster is an interactive text-based program that plays several audio file types (MP3, Ogg Vorbis, wav, and sid). It is one of the few audio players for the text console that allows full interactive control during playback. One of its key features is the ability to compose a very flexible playlist (while playing!). It plays most MP3 formats and has full mixer support built in.
somaplayer is music player for MP3, Ogg, wav, audio CDs, MP3 streams, and Ogg streams. It is able to use the appropriate sound drivers or demons or to stream directly to an Icecast server (Icecast2 or SHOUTcast) or to encode in MP3 and Ogg Vorbis. It also acts as a sound daemon that is able to accept connections from other somaplayers or any other sound player (xmms, mpg123, and others) thanks to a special wrapper.
