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.
mgadvd is a Matrox G200/Zoran 36700 hardware MPEG decoder driver for Linux. It allows you to play MPEG-1, MPEG-2, and DVD streams through the Zoran 36700 Vaddis III decoder (connected to the G200) with very low CPU usage. Supported DVD audio formats are AC3 (Dolby Digital) and PCM. Included is a player app called mzplay that plays DVD directly from the disc as well as MPEG-1 and MPEG-2 video and audio (Layer II only) files.
webCDwriter can be used to make the CD- and DVD-writer(s) connected to a Linux box available to all users in your network. It consists of the server CDWserver and the clients webCDcreator and rcdrecord. CDWserver stores the files transmitted by the clients, reserves the CD-writer and controls the CD-writer using cdrecord. webCDcreator is a Java applet that runs within your browser or by Java Web Start, assists you when putting together a CD, and transmits the files. Finally rcdrecord is a command line client that tries to offer the functionality of cdrecord over the network with full multi-user support.
The Music Control Center can help you organize your existing sound file collection and walk you through the process of ripping backup copies of your CDs, moving the newly-created sound files to the correct location, and updating the database appropriately. It allows you to create playlists on-the-fly, save them, and load them for playback at a later date. You can search your collection by artist, album title, label, producer, song title, and year released.
The Helix DNA Server is a universal media delivery engine that supports the real time packetization and network transmission of any media type to any device. It includes support for MP3 audio (.mp3), RealAudio, and RealVideo (.rm, .ra, .rv). Other data types are supported through the Helix Universal Server. It uses RTSP/RTP streaming delivery for standards-compliant clients and proxies, an RTSP cloaked protocol over HTTP, and media data delivery via TCP, UDP unicast and multicast, and HTTP.
Music Player Daemon (MPD) is a server that allows remote access for playing music in various formats and managing playlists. It makes a great desktop player with frontend options (Qt, GTK, ncurses, Windows, and Web clients are available). It is also appropriate as a console player that is scriptable, and is especially useful if X is restarted frequently. A set of rapid development tools for clients are being developed and include a C library, Python module, PHP class, Perl module, and Java Class. The goals are to be easy to install and use, to have minimal resource requirements, to be stable and flexible, and easy to interface.
ShoutCastProxy is a system for saving bandwidth when multiple users in different rooms are listening to the same ShoutCast audio stream. ShoutCastProxy runs on a central server, and connects to whatever ShoutCast server that a client requests. If multiple clients request the same stream, the stream will be downloaded from the original source only once, but will still be sent to all the clients. Multiple proxies can be chained together.
