is stereo or joint stereo optimum for encoding at 192kbps? i notice that mp3enc 3.1 stops using joint stereo at 192kbps. im looking towards music archival with emphasis on maintaining the higher frequencies (16khz+), should 160kbps be enough? any input? recommenations on stereo modes and bitrates would be helpful... -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )
