I'm trying to make a 10-band equalizer and the kAudioUnitSubType_NBandEQ audio unit seems the way to go, but Apple's documentation doesn't cover how to set/configure it.
I've already connected the nodes but it errors out when I try to connect the EQNode with the iONode (output): https://gist.github.com/2295463
How do I turn the effect into a working 10-band equalizer?
Update:
A working DSP formula with Novocaine is also a solution, any ideas! Those DSP formulas are quite complicated.
Update2:
I prefer a working DSP formula with Novocaine since that'd be much cleaner/smaller than programming Audio Nodes.
Update3:
"The Multitype EQ unit(of subtype kAudioUnitSubType_NBandEQ) provides an equalizer that can be configured as any one of the types described in "Mutitype EQ Unit Filter Types" (page 68)."

But still no example.
