In that spirit, here's an excerpt from the latest Mastering Engineer's Handbook 3rd edition that provides 3 tips for a better sounding iTunes encode.
"There are a number of tips to follow in order to get the best sound quality from an iTunes encode. As it turns out, the considerations are about the same as with MP3 encoding:
If you back it down to -0.5 or even -1 dB, the encode will sound a lot better and your listener probably won't be able to tell much of a difference in level anyway.
3. Although the new AAC encoder has a fantastic frequency response, sometimes rolling off a little of the extreme top end (16kHz and above) can help the encode as well.
Any type of data compression requires the same common sense considerations. If you back off on the level, the mix buss compression and the high frequencies, you’ll be surprised just how good your AAC encode can sound.
Remember that iTunes still does the AAC encoding. You're just providing a file that's been prepped to sound better after the encode.
