yes the files came off my tape into soundforge, went up to 24/96 for some eq and loudness and then dithered back to 16/48 wav. since soundforge is sector boundary friendly, I divided the files there then batch converted them in TLH into flac and seeded.... someone then took those files, turned them back into wav and tested... almost ALL of them reported MPEG ! crazy !!
If you read some of my comments, I am thinking that the double conversion is going to flaw pretty much anything you try.... I've read endless reports of lots of people here getting different results even from the subjective spectral... seems there is NO definitive test after all ??
