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.

edited: had some troubles posting the link ;)

bye,
Sebastian

... Hence I believe, as tigre pointed out above, that empirical analysis such as spectrograms are only useful during tuning, bugfixing, etc. but ABX/ABC-HR tests should be used as the final judge of an encoder since that is ultimately what a perceptual encoder is used for.....compressing audio for our listening.

Totally agree.

My impression is that you are judging my encoder based on looking at the frequency response of original/compressed white noise.  In my opinion, that is not an accurate or fair way of judging any perceptual coder.

Agree, it isn't. I'm using it *only* for judging concerning the energy preservation issue. I don't complain about a lowpass-filtered signal or whatever ...

I really do appreciate your efforts. Though, it would have been cool, if we had discussed the tuning approach itself.

bye,
Sebastian
