I tested vorbis. I sounds good, but when I play something in mono, trebles are much stronger. Perhaps is stereo phase of hi bands removed to improve compression ? I't a good idea (it's not audible in most music), but it should also provide an option to preserve them. Is there docs that explains how dows vorbis compress sound ? oggenc (yearstday's cvs) creates only ~128k streams. Older versions worked fine at any bitrate.

If you have two 128kbps files, one stereo, one mono, the mono file has roughly twice the bits to allocate to "each" channel. You'd have to get up over 200kbps to get a stereo file that sounds that good. Depends on how much the channels differ, I suppose. Perhaps that explains what you're hearing? ----- Original Message ----- From: "Giuliano Pochini" <pochini@denise.shiny.it> To: <vorbis@xiph.org> Sent: Saturday, November 24, 2001 4:34 PM Subject: [vorbis] Hi all !> > I tested vorbis.
