Hello all, Updates of jconv, now called jconvolver, and the zita-convolver library are available on the usual place: <http://www.kokkinizita.net/linuxaudio/downloads>/ The new zita-convolver is API-compatible to the previous release but not binary compatible. If you have any code using it please recompile. Release notes for jconvolver and fconvolver 0.8.4 ------------------------------------------------- Jconvolver is a real-time convolution engine. It can execute up to a 64 by 64 convolution matrix (i.e. 4096 simultaneous convolutions) as long as your CPU(s) can handle the load. It is designed to be efficient also for sparse (e.g. diagonal) matrices. Unused matrix elements do not take any CPU time. In contrast to e.g. BruteFir, jconvolver uses multiple partition sizes, small ones at the start of the impulse response and progressively longer ones for the rest. This allows it provide both zero processing delay while still remaining efficient in CPU use. Fconvolver performs the same processing on files instead of real-time. For this relaese the package and the binaries have been renamed to avoid a conflict with an existing 'jconv' package (related to the Japanese language). Functionally this version is identical to jconv 0.8.0. See README.CONFIG for the syntax of the config files. Since 0.8.0 it has been possible to name and connect the Jack ports. The related commands have been added to README.CONFIG. Jconvolver will work with libzita-convolver 1.0.0, but upgrading to 2.0.0 is recommended. Note that if you update the library you have to recompile this package. NOTE: Jconvolver will normally not work correctly when used with Jack's freewheeling mode, e.g. when exporting in Ardour. It _could_ actually work when used on a single processor system, but don't rely on this. This release of jconvolver will print a warning when freewheel mode is entered. The 'mkwavex' utility from previous versions has been replaced by 'makemulti' which offers some more options. Enjoy ! -- FA Wie der Mond heute Nacht aussieht ! Ist es nicht ein seltsames Bild ? _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
