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.
Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
Paloma is a program to manage an SQL database of digital music files, and facilitate their retrieval and playback in interesting ways. It works with music files of any form -- MP3, Ogg Vorbis, MIDI... whatever you've got a player for. Paloma makes it easy to rip your entire CD collection and store it on your hard disk (or a collection of CD-Rs) for instant random access; playlists can then be generated using arbitrary SQL commands.
Rumor is a realtime monophonic (with chords) MIDI keyboard to Lilypond converter. It receives MIDI events, quantizes them according to its metronome on the fly, and outputs intelligently handwritten-like corresponding Lilypond notation. Tempo, meter, key and other parameters can be set via commandline options. Rumor can use ALSA/OSS or emulate MIDI input with computer keyboard. It is scriptable with Guile. It has been tested on several major J. S. Bach organ pieces (see links to Mutopia in the documentation).
FMS is a tool to create all kinds of sounds from scratch. You can play any sound (sine, triangular, vowels, etc.) with any property settings (frequency, volume, balance, sweep, etc.) and modulations thereof. It also features tools to save sounds, play .MUS music, graphically display sounds, and make real noise.
OrganDesigner is a graphical tool for editing and configuring virtual pipe organs. OrganDesigner can read SoundFont files and can both read and write organ description files for use by the virtual organ MIDI player GENPO. OrganDesigner users can copy, move, and delete stops, both within and between divisions; use the Stops Editor to change a stop's name, MIDI bank, program, and velocity; use the Divisions Editor to make new divisions, change a division's name and MIDI channel, change the order of divisions, and delete divisions; use the Couplers Editor to add, modify, and delete couplers; use the Pistons Editor to add, modify, and delete combinations, and to store and recall the stops set for each piston.
