Is there a way to convert a VBR MP3 in 5.1 channel to AC3 5.1? Actually, I'm not really sure if this is 5.1 channel. Here's what it says in GSpot;

0x0055(MP3) ID'd as MPEG-1 Layer 3
122 kb/s (61/ch, stereo) VBR LAME3.98aª
48000 Hz

That can't be mp3 can't be a 5.1.

122 kb/s (61/ch, stereo) VBR LAME3.98aª

that means 61kbs per channel and stereo.

mp3 supports multichannel (yeah, real multichannel, not fake surround info), tough no encoder supports it (also not lame)

both frauenhofer and the aud-x are "surround" mp3 encoders, meaning they output stereo mp3 files which contain some extra infos for how to upmix from 2 channels to multichannel

both are not compliant to both the official mp3 surround and multichannel specs
