Odd question...
Current iPod Nanos and Classics are advertised to play AAC up to 320, however, I was curious what they do to AAC above that range.  I have true VBR AAC files that are in the mid 300s and due to being VBR have portions that are going to be even higher than that.  They appear to play properly, but I was wondering if anyone knew if they were being altered by the player since they are over the max spec listed. Thanks.

IPods can play ALAC (over 1000kbps) so don't worry about those specs

Isn't AAC above 320 mostly for multichannel sound?

Certainly offers no sonic advantage for 2 channels...don't know why anyone would...

Not using if for multichannel, just shot some lossless files through XLD using true VBR AAC as output.  Ranged between 180-360 or so and wasn't sure with iPods having a max AAC spec below the bitrate of some of the files.

Really shouldn't be a problem, and if it sounds good, it's working.
 
But I'm personally not a fan of VBR anyway.  Once you're at AAC at 320kbps, your job is done.  You're probably trying to save some space with VBR, which would be valid, but you should be able to cap it at 320 with XLD.  Really, above 256, AAC is transparent enough to make anyone happy, not much point in anything higher than 320 anyway.

Thanks for the responses, looks like it's no problem.
