If you are running Linux, there might be a way to burn the tracks to a virtual CD via some sort of script, then analyze that virtual CD via Tau. Way over my head tho ;) You could maybe do something with MPTrim to detect gaps, but that's only if the MP3s contain gaps, and then also only if the original source didn't also contain gaps. I don't think that's good, and you could risk screwing up your files unless you were careful. If only flac allowed you to set a lowpass filter, and then encode everything below that cutoff losslessly. Then you could reencode it to FLAC, then to a second FLAC with a 16.5 KHz cutoff. If the two FLACs are identical, then the source contained a lowpass filter. Just thinking out loud. None of my suggestions actually work...but maybe there's another lossless codec that does support a lowpass? -- CatBus ------------------------------------------------------------------------ CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=28710 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
