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.
as-gps contains a basic support library for accessing the inexpensive ($20) Aisin-Seiki GPS Module previously available at mavin.com. The package also includes several simple console utilities for dumping satellite status, location, and time and for synchronizing the system clock.
AutoOpts is an integrated part of AutoGen. Based on a very simple option description file, it will process configuration files, environment variables, command line options, text strings passed by client programs, and will make the results easily accessible to the client program. It will also produce a man page and the info-doc invoking section automatically.
AVLMAP is a key:data pair data mapping (associative array) library for C programming based on AVL balanced binary trees. Added features include ordered data retrieval forward or reverse, support for optional duplicate keys (e.g. an extra linked list not needed), and the ability to find the nearest member if an exact match isn't available. Both key and data types may be selected from a choice of C data types including string and array variations. One mapping always has one key type, but data types may be mixed within a mapping.
Awka is both a translator of AWK programs to ANSI C, and a separate library against which the C code is linked. The aims of Awka are to allow creation an executable that provides generally better performance than AWK interpretors, to allow easy inclusion of AWK logic in larger C applications, and use of external C functions within AWK scripts.
Beast is a powerful music composition and modular synthesis application. It offers multiple input methods like multitrack, piano roll, and pattern editing and supports skins. On the technical side, it has a wide range of abilities like sequencing, unlimited undo/redo history, real-time synthesis with multiprocessor support, full duplex 32-bit audio rendering, precise timing down to sample granularity, on demand loading of partial wave files, on the fly decoding of various sample formats, aliasing free oscillators, and full Scheme scripting support.
