Dolby Pro Logic 2 2001-12-16 17:21:04 Hi,I tested DPL2 this weekend.Fantastic surrounding.Test materials:CD (CDDA) of German magazine "Stereoplay" with special songs which include DPL2 infos.Eg. Erich Kunzel: Pink Panther and some more fantastic tracks.Amplifier:harman kardon HK AVR 5000 , surround mode for decoding :Logic 7 (in aspect of functionality the same as DPL2 !)a TYT 2000 clone: Grundig GDV 130 as (DVD) MP3 decoder / CD-PlayerSony DAT DTC 670 as digital & analogue reference (for A/B-comparisons : original wave / MP3 )I encoded the waves to MP3 with dm-xtreme or alt-extreme, sorry cannot remember, if I had changed my settings and versions already.....My results:It seems that MP3 copes with DPL2, probably with joint stereo, too.MP3 joint stereo worked with DPL, that is a well known fact.(I tested myself with special DPL songs, yes, I confirm that personally.... (if somebody should be interested in my opionion)) So as xtreme setting produced enough joint stereo frames in that test songs, I would confirm that phase information is kept well.Well enough for DPL2 !!That would be fine.It would be even finer, if somebody (perhaps of Dolby company) would confirm that their DPL2 signals work really well with songs encoded to MP3, joint stereo.
