Hi,
Can someone please explain the concept of "inverse filtering" and how it applies to SBR encoding?

Why is it used?
Does it improve quality and how?
How do we esitamate it's level (needed by sbr decoder)?
Etc...

Any web links are also welcome.

Thanks,
Daniel

Anyone?

Sorry, I do not understand that too. But I have searched AES(Audio Engineering Society) papers, I found many papers related to the "inverse filter".

But you should have a membership.
