Split from here.

Please tell me some details about your HF boost reduction strategy.

Maybe my posting at
Ogg Vorbis - General
is of some interest.

Accorgint to "the white noise test" i did with your encoder
( see my paper )
you did not seem to fix anything.
Please don't say you've reduced the HF boost effect withoug even knowing the cause.

Correct me, if i'm wrong.

(The things i'm saying in the paper are valid vor q>=6 and somewhat applicable for q<=5)


I think we are referring to different problems. The HF boost that I and other people have noticed to be reduced, through listening tests on real life music samples, is the excessive brilliance of transients in hi-hats and cymbals. I don't claim to have fixed the source of the problem but I've patched to reduce the effects in cases that are most noticeable. Read the listening tests people have done rather than looking at frequency responses of artifically generated test signals.
