Everybody knows the best way to store atrac files on our discs is PCM/APE/FLAC/AAL--->ATRAC But sometimes, we have a great difficult-to-find album in mp3 format, and we cannot get the original (loseless) format of it. I´d like to make a conversion bitrate table, where we can say what´s the best bitrate option (atrac) for every mp3 bitrate we EVENTUALLY could have. (Yes, i really HATE mp3) The idea is to store the mp3 audio in atrac files, getting the best balance quality/disk space. For example, it would be very stupid to store mp3@128 as atrac@256 (we´ll get extra disk space without any quality improvement). As a start... let say, mp3@128 --> atrac@64 (as i read in the forums) mp3 bitrate - best atrac bitrate option 128 64 160 . 192 . 224 . 256 . 320 . VBR?? ???
