[Ardour-Users] OT: Plug-in development

[Josh Parmenter]

Hi Michael,

I think there may already be a LADSPA B->UHJ ... I'll check. In the  
meantime, I have one built for SuperCollider if you are in need of an  
algorithm. The phase shift is done with 6 cascading First Order  
Sections, an is pretty efficient (though the upper octave has phase  
distortion... expected with this technique).

The code itself is in C/C++ already. If it would save you some work,  
I'm more then happy to share.

Best,

Josh
