Wow - thank you! This sounds amazing indeed! I really look forward to trying out Aella! For now I will be trying jconv at a tme where there is some time:-) Best regards Ketil Fons Adriaensen skrev: > On Fri, Dec 14, 2007 at 02:06:22PM +0100, Ketil Thorgersen wrote: > > >> I have been browsing for convolver/impulse respons plugins for linux and >> have found a few: brutefir, jace, jack-convolve and dssi-convolve.
