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.
ccaudio2 is a simple, highly portable, stand-alone, C++-based framework for manipulation of audio data. Its goal is to be a C++ framework that is as useful as "audiofile" or "sndfile" is for C programming, and to cover various generic and useful manipulations of audio data as well as audio file access. A stand-alone audio processing command line tool is also provided to demonstrate library functionality. ccaudio2 compiles under Mac OS X, POSIX systems, and Win32 systems.
The CDDB/CDDB_get Perl module gets the CDDB info for an audio CD. The included script was intended as a demo for CDDB_get, but over time it has gained powerful features like the ability to write to a database, offline mode, HTTP mode (including proxy), saving in standard XMCD format, and writing 'lame' commands.
jMusic provides a library of classes for generating and manipulating music, and is a solid framework for computer assisted composition in Java. jMusic supports composers by providing a music data structure based upon note/sound events, and methods for working with that musical data. jMusic can read and write MIDI files, audio files, and its own .jm files. jMusic is designed to be extendible, encouraging you to build upon the functionality of jMusic by programming in Java to create your own music composition tools.
libgaudio is a C/C++ library to facilitate easy incorporation of sound and sound effects into games. Samples are loaded into memory and playback is then triggered or stopped. The system mixes any number of concurrently playing samples together (up to a predefined maximum). It is also possible to include a background MP3 soundfile in the mix.
libmidixx is a C++ library to manipulate MIDI sequences. It is intended for a multimedia application that handles playback, recording, and editing of MIDI sequences, though the current version just implements playback only. libmidixx supports OSS, ALSA, and serial (tty) MIDI ports, and also comes with a user-space sequencer implementation, which does a fair job on a lightly-loaded machine.
libSap is linux port of windows' SAP Library which is a software emulation of CPU 6502 microprocessor and Pokey chip. Those two chips are used in Atari XL/XE computers. SAP Library is used to run programs written in 6502 machine language that are using the Pokey chip to play tunes and sounds.
