[PD] [PD-dev] denormals: svf, freeverb (was Re: bug in freeverb???)

[Ed Kelly]

Hi Damon,

I have tried to implement this technique, to fix the svf~ and I am still getting denormal errors pegging the CPU. Is there anything I have missed do you think? After reading a little bit about unions and uint32_t I think I've used them correctly...

If this bug can be zapped for good then I'd like to eliminate denormal errors from the svn for good!

Best,
Ed
