well, i can't write everything i have to say about stereo (not dual-mono or joint), but earlier i got my hand slapped for using APS with Stereo and Q0... after reading how Q0 is experimental, are there any switches that CAN be used to get a 192-224kbps file with the stereo switch?
now before the whole "there's no noticable diff between stereo and joint-stereo" argument starts, i'd like to note that i like playing music in 4.0 at home, and used to play it in 5.1 at the theater i worked it. (done by matrixing out the channels according to their image(?) or whatever .. can't remember, just read it recently on the dolby site)
i use the 5point1 plugin for winamp http://classic.winamp.com/plugins/reviews....OT=C&rOI=122003, which, as far as i know, doesn't break the music per se. high bitrate stereo MP3s and medium bitrate OGGs play back damn good, and Lossless plays back simply stunning. it's how theaters pull at least 3, if not 4 or 5 channels out of 2 analog Dolby SR channels (which i'd say predates Pro Logic 2, and probably even the original Pro Logic) on the filmstrip.
all i know is APS won't cut it with joint-stereo, and using APS with stereo was highly discouraged. are there settings that are suggested with stereo?
ps: i don't know why i didnt' think of this earlier, but i made some samples today with the plugin (using just the Rear Left and Rear Right) + Cool Edit in case people couldn't/didn't feel like testing it out to hear how badly JS munged the sound. how should i do it? MPC/OGG/MP3 (dual mono or something) on website? or LPAC/FLAC/APE on bittorrent (i have a 24k upload) if someone has a tracker i can use? .... or FTP? (you gotta be smart enough to get around the router... plus it's on a non-standard port)
