Hi All,
A small correction to my previous query.Instead of Quality improvement in my
2nd line, please read it as Compression Improvement.Sorry for the trouble.

Hi All, 
I would like to get some info regarding the tradeoff between Utilization and
processor power required for Perceptual Noise Substitution (PNS) as used in
MPEG 4 AAC.Here by  Utilization I mean the Quality improvement of audio by
using PNS.
I would also like to get some info on testing PNS.In case testing is going
to take more time for the probable quality addition, I was wondering whether
I can opt out of using PNS.Is there a correct way of generating the Random
numbers,or can we define our own method???There was no mention to be seen
regarding this in the standard. 
Thanks and Regards, 
Kannan
