Should I convert all my audio to 256 AAC?

Hi all, I'm currently researching what the best route is to go with when converting over my CD library. I realize that everyone loves Lossless (which I'll use for archiving the CD's) but I'm looking for "the best" lossy encoding.

I was originally planning to encode all my CD's into 320 CBR but it seems that almost everything I read states that this is a waste of space as their is nary a difference (except to the most trained ears) between 320 CBR and VBR v-0. Ultiamtely, I don't mind the difference in space when on my computer hard drive but it does become more of an issue when uploading to my iphone for portable listening so then I switched course and started thinking I would go with VBR v-0 (I posted a similar question to this in the mp3 forum) but now I'm reading that I may even be better off going with AAC 256?

This may make the most sense for me being that I'm a Mac user (imac, iphone, ipad) and I'm going to playing all my music out of my itunes library.

Is there any reason I would regret the decision to go AAC over mp3?

Also, for those with experience with this, could you direct me to the best possible setting to use in XLD for encoding CD's/FLAC files to aac?

Exactly. If the music's complexity doesn't require lots of bits then the encoder produces smaller frames. Don't get hung up on the bit rate - it's an incidental outcome of the perceptual transparency ("quality") you are trying to achieve. For example, after lots of reading and lots of comparative listening tests (some ABX, some not) I settled on LAME V2 for most of my encoding, and on some albums get average bit rates around 130 kbit/s, while on others it will average around 220 kbit/s. I don't care, they still sound fine. smile.gif

For XLD (Quicktime) encoding you have three choices when it comes to picking a quality setting:

1. Do your own listening tests with a range of quality settings
2. Read around to see what settings others are using
3. Use the default / recommended setting

1. takes time but will give you results that you know work for you, 2. relies on other people, not all of whom can be relied on to be impartial or accurate, 3. assumes that the developers have done 1.

Based on my experience with LAME - settling on V2, which is towards the top end of what many people recommend for casual or portable listening to non-problem genres, and is what many people would casually recommend - I'd suggest that some test encodes using the default settings (110?) might be worthwhile, but it all depends on how much time you want to spend.
