If the default lowpass is 20000 for the CD-players then why encode higher if all the things that are above this frequency are noise?

Because we don't play our MP3/OGG/MPC/AAC files on a CD player?

Hehe, thought myself of this... but you should've answered:

Let the ath implementation decide whether what's above 20.000 is just noise or usefull stuff

Of course, the above is true just for a very fine tuned encoder...

Was mentioned in this thread:

Not everything above 20kHz is just 'noise.' Some of it is aliasing, but some of it is content. Of course, very few people hear that high so it's not like it really matters . . .

Should that other thread really be off topic?

Well, if it is then I should have posted here instead. Anyway, my reply is at the end of the other thread (linked above).

Thanks!
