Well, I spotted the lowpass, but I don't know where to modify the ch coupling. Could you help me out? It would be great if it would be made avaiable through "vorbis_encode_ctl", or is it already?

Oh, OK, thanks. But I hope that you keep an eye on material which is Dolby Surround encoded. With the "old" vorbis only in "light lossy" and "lossless" coupling modes (ie. setting the stereo_point_db to 0 and 1 IIRC) the DS infos (phase correlations) seemed to be reproduced faithfully.

Do you have a DPL(2) amp to test?
