AAC settings for speech/talk

I am about to encode a lot (200+) of short interviews from AIFF to either AAC or MP3 to listen to on my iPod and would appreciate a starting point for which settings to use.

Space really is not an issue but the resulting files should be as small as possible (of course;-) with the reservation that hearable artifacts or distortion is not acceptable.

Besides, some of the interviews are in mono and some in stereo, can I encode everything in stereo and letting the joint stereo effect automatically handle the mono-recordings making them half the size of the stereo recording? Or is it necessary to manually encode in mono and stereo respectively?

With this in mind, what settings for AAC do you recommend?


A final general question, as far as I understand the AAC standard supports VBR but the iTunes encoder has a very limited support for VBR. Are there any encoders (CLI based is fine) for Mac OS X that supports AAC/VBR?

Mac OS X 10.3 and Quicktime Pro 6.5

The bit-rate could go low, low, low.. (apple uses 32kbps for their audio books)..

Just set channels to automatic in iTunes and it will use stereo for the stereo files, and mono for the mono files. (I'd just use mono for all, but hey)

iTunes AAC is abr, and is the best encoder around, just use that..
