So we've all seen the debate between 256 Kbps AAC vs 320 Kbps Mp3, and while many consider the differences to be almost negligible, people have come to realize that AAC seems to perform better with acoustic sounds, whereas Mp3 seems to handle electronic-sounding sounds better (synthesizers, wobble, etc), just from the different compromises they make when compressing audio.
That's well and good... but what about 320 Kbps AAC? I just noticed that iTunes will actually let me encode things into this using the custom options under the AAC encoder within iTunes.
I'm currently testing it out using is the Dream Theater anthology I have in lossless... I've (of course) made backups of everything, so I don't see an issue there.
Is it possible that 320 Kbps AAC will be better than 320 Kbps Mp3?
Keep in mind that they are both being converted using the same lossless source.
I'd like to get some more opinions on this, as there are some songs in lossless that I don't like as much. My absolute favorites, and most masterfully recorded albums, I want to keep in lossless, but for other stuff, I'd just like really good quality, paired with archives in lossless for the future.
