I don't know if I have one that is so little compressed. The most I've picked up here & there was 96 and below, usually with an un- known history. Even 128kbit mp3 can be detected in a few seconds. Here I have done a/b testing against some well produced cd's I've ripped, and with ogg running at Q7, which gives a filesize similar to an mp3 at 128kb, and cannot tell the difference. Back these ears up 55 years to before I started wearing out rifle barrels, and I expect they might detect the diff. > By all means talk about low bit rate encodings and how they are no > good, but please folks - double blind testing doesn't lie, and the > double blind tests are close to unambiguous at this point.
