I still find myself fighting denormalization in my code.

P.S.: I filed a request to ADC for a tech paper about Denormalization on the Mac several months ago. Still nothing except a "be patient"-reply.

You probably should read this :

http://www.musicdsp.org/files/denormal.pdf

It has been made by one guy of our dev team, it does not use non-IEEE mode, and all solutions are exposed. We have been using those methods for all our plugin here at ohmforce and it has always worked perfectly *without any asm*.

I hope this will help you. Keep me posted if you want some more info from that guy himself.

He he,

I currently use one of these methods, but I want to get rid of them since the PPC _can_ be set to non-IEEE mode. I just don't know how to set the registers appropriately :-)

It is a very good reading, anyway.

However, I have lots of small buffers to deal with in my AudioUnits, and due to modular architecture, I will add a small AC at Nyquist several times to prevent the cpu from going mad. Not needing to do this would save many cycles :-)


Cheers,

;) Urs
