Interesting how they say that aac provides quite good quality at 256k,
and of course now the BBC uses mp2 at 1/2 that rate. It's hard to see
any logic in thinking that 128k mp2 will be acceptable, when back in
1999 they considered 256k aac as only "quite good".

I think you've misread it.

256kbps AAC was quite good for 5.1 surround sound!

128kbps AAC is excellent for stereo.

I'm fairly sure this is the report they're referring to...

....which is basically BBC R&D saying "please switch to AAC now, mp2
isn't good enough while AAC is excellent".

That's even before they thought about reducing mp2 bitrates to
128kbps!

Cheers,
David.
