Re: [Sc-devel] APF fix

It is an Allpass Filter, and it already exists (has been there for some time), but I don't believe it works correctly. That is why I believe this fits under 'bugfix'. Not a new feature... just making one that is already there work. It was definitely there in Nov., and I think it has actually been in much longer (I think I remember trying it year ago, but it didn't do what I expected).

Unlike the Allpass delays, this is a second order section kind of filter (rather then a delay line where the delay length is based on freq)

Never heard of APF before, and there's no help. What's it supposed
to do?

all pass filter I assume.

Let me know, and I can commit before the final 3.2 rolls out.

Remember that the final 3.2 may already be out ;)

In practice though, if we're finalising the volume slider and a few
other tweaks, there probably will be a R2. Would be good if we could
settle soon though so as to have a final further testing period.

I'm trying to be really explicit about the RC process so that people
understand it. (Not saying Josh doesn't understand it, just that we're
all a herd of cats.)

I think it's quite likely that the devs will collectively "vote" for a
second release-candidate. However, none of the issues that have come
up yet have been real showstoppers, so we'll have to discuss, maybe at
the end of this week?
