Thanks for that! I am concerned that I will never be able to recover the original volume settings. Apart from the advantages of FLAC being better quality than mp3, I want to be able to recover the exact WAV in order to keep my options open. I don't want to have to re-rip anything ever again even if I want to change format for some reason! I'll copy the rest with the normalisation off and then gradually re-rip those I've done at some later date. Of course, it is not urgent! -- jimmy ------------------------------------------------------------------------ jimmy's Profile: http://forums.slimdevices.com/member.php?userid=616 View this thread: http://forums.slimdevices.com/showthread.php?t=13583 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
