BEQSuite and Regalia Mitra filters

[Josh Parmenter]

Hi all,

i just committed a change to the BEQSuite filters (in svn). The filters now all use doubles for the filter coefs. I can hear a little difference (seem smoother in general). Also... They don't seem to blow up as easily (I would get infs on occasion from them... these seem to have disappeared for me). 

I'm also getting ready to do a set of UGens of the Regalia-Mitra Allpass based EQ filters. I have two Allpass filters that could either be in the main dist, or just in this RMEQSuite... Allpass1 produces a 90 phase shift at the indicated freq, Allpass does 180. Now... APF has never really worked properly, and I think the Allpass that I am building would actually work well there. What do others think? I'll post the code and a build when they are ready (hopefully tonight).

James H. - the RMEQ suite is based on the classes that Joe Anderson built (and I think you use them in your dewdrop lib). The UGens should be a bit more efficient... is there anything special that you would want to make sure the UGens do? I am planning on the parameters being either all audio rate or all control rate modulatable... but if you need something more specialize (like, freq audio rate, rq control rate) let me know and I can work that in. 

Best,

Josh

Very nice!

I don't have any special requirements like that -- well, I'm assuming you'll be able to feed in an audio rate signal but modulate controls at control rate.

My classes are designed for relatively steady state EQs. Actually I would be very glad to get rid of the kind of clumsy biquad transform in my code :-)

Won't quite finish the RMEQ stuff tonight (but have a good start).

Also - I noticed a strange bug in the BEQSuite with the ZXP pointers. This is now fixed.

More tomorrow!

some time ago, i have ported my regalia-mitra filters from nova to
supercollider: http://tinyurl.com/6rw72x
they require some headers from nova's templated dsp framework (mainly
http://tinyurl.com/5ocyr5), but maybe they are a good starting point ...

As I've said before, I think BEQSuite should be in Common.

Basic EQ is something new users always want to know how to do, and BEQSuite definitely simplifies that.

Any reason not to add it?

I'm fine either way..... though with the changes I just made, some testing is in order :)

I'm curious why this message was directed to the old list, when Josh's original message was to the correct bham address. Must have hit reply, then removed the correct "to" address and replaced it with the old one?

BTW, thanks to a little help from Marije, Stephen Travis Pope is going to put a forward/auto-reply in place on the old lists.

i am reading/posting through gmane's nntp ... maybe one of the list
admins could get in touch with gmane to change the address?

Okay, I've asked them to. For some reason the users list got changed  
but not the dev.

Hi all... the first version of the RMEQSuite is now in sc3-plugins  
svn. No helpfiles yet (so I'm not going to announce) - but James... if  
you want to try them out, the RMEQ UGen is there (replacing the RMEQ  
class).

More soon. A second shelf filter will be on the way... maybe some  
others.
