For the software I am using: - jconvolver to correct the sound with pulses calculated by drc with impulses measured with aliki. - ambdec to convert from ambisonics to the specific speakers. "Normal" music listening I do without ambisonics as I don't have the additional speakers powered on all the time. But it is also nice to use the ladspa stereo-to-amb panner to move the stereo speakers in the room. I am thinking about adding a 5.1-to-ambisonics mixer/panner to move the specialized channels with their defined positions to virtual sources in my ambisonics surrounding. Don't know if that works out... Have fun, Arnold
