BruteFIR is a software for applying long FIR filters to multi-channel digital audio, either offline or in realtime. Its basic operation is specified through a configuration file, and filters and attenuation can be changed in runtime through a simple command line interface. The FIR filter algorithm used is an optimised frequency domain algorithm, partly implemented in hand-coded assembler, thus throughput is extremely high. In realtime, a standard computer can typically run more than 10 channels with more than 60000 filter taps each.
SPAG is a mouse-driven GUI for building and browsing fact/information trees. Flexible arrangement of graphics and text with colorisation produces an environment for information presentation as an interactive style of instruction manual, for general note-taking allowing unlimited annotations/jottings, or for reference material storage. Tree structure allows for rapid navigation through vast amounts of data, while visual style presents information in an interesting manner.
Avifile Glue for mpeg2_movie started as a simple patch against heroinewarrior mpeg2_movie to utilize libavifile, however the project got out of hand and currently supports the Nuppelvideo file format for input and the MJPEGtools' mpeg2enc YUV4MPEG format for output. Originally, this project's intent was not to become a new package, but only to provide direct AVI to MPEG conversion for the GNU/Unix/Linux community until the core feature (linking against libaviplay) was integrated into the main encoder, but this goal has been abandoned. The project's current goad is to enable as many encoders as possible with the ability to read AVI, NUV, and QT.
