If true, this would be great news for Mini owners. Being able to encode at 64 kbps with CD quality results would essentially double the song capacity. Has anyone tested the AAC+ codec to verify the quality claims?

I’m assuming that the sound would be similar to MP3pro vs. MP3—more compression with the same sound quality, but (at least to my ears) a more fatigueing sound. Is this in prep for Apple’s flash-based iPod?

AAC+ or AAC-HE is actually a AAC-LC with SBR (Spectral band replication)

64kbps AAC HE is a 22.5kHz AAC-LC+SBR information (to reproduce hghi frequency signal cut off by low pass filter)

And yes, it don’t sound good as AAC-LC at 128kbps.

AAC-HE don’t suite music application (that required hifi audio) but I think it has potential in mobile phone application or high quality voice codec

I tested Nero’s AAC-HE encoding capabilities.  A 64 kbps sounds better than a 128 kbps AAC-LC.  CD quality is achievable at 48 kbps for AAC-HE so 64 kbps is a bit more, kinda like how CD transparancy is achievable with 96 kbps MP3pro.  I am thinking about ripping my tracks again but that would be alot of work especially if Apple didn’t AAC+ support to the 3rd gen. iPod.
