Hi, this release adds another dependency: libDSP 5.0.1. This version of libDSP provides an optimized complex multiply-add which drops dsp usage for a 1 sec stereo IR from 14 to 11% on my 1.2 ghz athlon (133mhz sdram) at a jack periodsize (= partition size) of 2048 frames.. grab it at: http://www.affenbande.org/~tapas/wiki/index.php?jack_convolve -- Palimm Palimm! http://affenbande.org/~tapas/
