METAXPON ("Metachron" in Greek letters) is a small and fast audio DSP library for time-scale manipulation of 16-bit integer or 32-bit floating point stereo audio data streams. It employs a rigid phase-locked vocoder with dedicated transient detection and processing, and can work in real-time or non-real-time. Four editions are included - a portable edition and three x86 editions. The portable edition can be built with any ANSI C compiler and is OS- and architecture-independent. The three x86 editions are written in assembly using the FPU, 3DNow!, and SSE instruction sets, respectively, with automatic selection between them depending on the CPU capabilities. They can be compiled with MASM, JWASM, or NASM, producing libraries of object files in 8 formats.
OwfsWeather is a package that scans and logs weather data from various One-Wire weather sensors. It uses OWFS, the One Wire File System, to communicate with the sensors. It currently supports logging of weather data to Weather Underground, a CSV file, and to an RRD database. Current hardware supported is the WSI-601 weather station from AAG, a DS1820 temperature sensor, and the humidity and barometric pressure modules from Hobby Boards.
