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.
Jam2 is a collection of components for the Drupal 4.7 CMS platform. It provides a number of new node types aimed towards allowing independent musicians to upload media and cover art, add album and artist data, and create and manage podcasts of new material or previously uploaded jams. Uploaded media can be presented to the user as an embedded Flash player, a download link, or both. Users can create podcasts that feature the full array of iTunes tag data, so that podcasts can be easily listed with the iTunes Podcast Directory. Albums, once defined, can also provide their own podcasts, allowing musicians to optionally involve their fans throughout the creation of an album.
libplayer is a multimedia A/V abstraction layer API. Its goal is to interact with Enna Media Center. libplayer provides a generic A/V API that relies on various multimedia players for Linux systems. It currently supports MPlayer, xine, VLC, and GStreamer only. Its main goal is to provide a unique API that player frontends can use to control any kind of multimedia player underneath. For example, it provides a library to easily control MPlayer's slave-mode.
irrKlang is a high level 2D and 3D cross platform sound engine and audio library that plays WAV, MP3, OGG, MOD, XM, IT, S3M, and other file formats. It can be used by C++ and all .NET languages (C#, Visual Basic.NET, etc.). It has all of the features common to low-level audio libraries as well as lots of useful features like a sophisticated streaming engine, extendable audio reading, single and multi-threading modes, 3D audio emulation for low-end hardware, a plugin system, multiple rolloff models, sound effects, and more. All of these can be accessed via an extremely simple API using an object oriented design.
PyKaraoke is a karaoke player which supports the CDG (MP3+G, OGG+G), MIDI (.KAR, .MID), and MPEG formats. The project consists of a GUI frontend and separate pycdg, pykar, and pympg player modules. The GUI provides a full application frontend, with playlist functionality and a searchable database. The pycdg, pykar, and pympg modules can also be used as standalone command-line players or imported into any Python programs that would like CDG, MIDI/KAR, or MPEG playback.
libkarma is a C library for managing the Rio Karma via TCP/IP. It supports all basic protocol commands and some advanced functions on top of these, like caching of the Rio database. There are two proof-of-concept tools included, riocp and chprop. riocp can be used to upload files to the Karma.
