This kind of vague cursory analysis and unsubstantiated statements isn't useful. Geez, isn't that what he said? opaqueice;277809 Wrote: Frankly, I very much doubt he would have been able to hear the differences between 320 MP3 or AAC and CD (at least not without lots of practice and choosing the test track very carefully), and after all the whining Stereophile has been doing recently that wouldn't look very good. Who's posturing now? opaqueice;277809 Wrote: I too use FLAC, and for the same reasons haven't paid that much attention to lossy formats. "HOWEVER MY IMPRESSION" is that the MP3 codec has improved considerably in recent years. One obvious thing is to use VBR (variable bit rate) rather than CBR. "AFAIK" VBR is always superior, and yet most MP3s don't use it. As for 320, "MY UNDERSTANDING" is that "IF" you know the weak points of the particular MP3 encoder you're using you can find of construct a track that will reveal them pretty easily. I've never seen a positive ABX result for 320 MP3, but I wouldn't be surprised "IF" they exist. Actually I'd say "A GOOD BET" is a strongly asymmetric test tone. You can hear absolute polarity inversion with that pretty easily, and "I THINK" all these lossy algorithms completely destroy phase coherency, so that "SHOULD" manifest itself as a subtle change in the pitch of asymmetric tones. "NEVER TRIED IT THOUGH". Thanks for the chuckles.
