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.
DAP is a comprehensive audio sample editing and processing suite. It currently supports AIFF and AIFF-C audio files, 8 or 16 bit resolution, and 1, 2 or 4 channels of audio data. The package offers comprehensive editing, playback, and recording facilities including full time stretch resampling, manual data editing, and a reasonably complete DSP processing suite.
DarkIce is a live audio streamer. It records audio from an audio interface (e.g. a sound card), encodes it, and sends it to a streaming server. DarkIce can record from OSS audio devices, ALSA audio devices, Solaris audio interfaces, and Jack sources. DarkIce can encode into MP3, MP2, Ogg Vorbis, and AAC formats, and can send the encoded stream to ShoutCast, IceCast 1.3.x and 2.x, and the Darwin Streaming Server.
dsproxy emulates an OSS device that "virtualizes" itself so each UID that opens /dev/dsp gets its own private sound device. At this point, simultaneous reading of /dev/dsp by another process "samples" the data out of dsproxy. The tagged audio data and ioctls stream may be saved to disk locally as the example program does, retargeted over a network, pushed into an effects generator (3-D sound), etc. The virtualization feature is a stepping stone to adding sound to VNC on a per-desktop basis with each user appearing to have total control over /dev/dsp. Most OSS ioctls are implemented, so applications such as xmame and rvplayer7 may be retargeted through dsproxy.
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.
GramoFile is intended primarily for transferring gramophone records to CDs, but has many other possible uses. It can record very long .wav files with a bargraph signal peak-level meter, playback any part of the files, split long .wav files into separate tracks (with automatic track location), and process the signal with filters to reduce ticks and pops (multiple filters are provided, they can be applied in any order (multiple instances) with user-adjustable parameters). Track splitting and signal processing are done in the same run, and don't need any temporary files.
