feature request -- pluto speaker equalizer filter types

[Bill]

I have built pluto (see linkwitzlab.com ) speakers, and they sound fantastic. I have a DSP crossover working (actually one each on linux, OSX and windows 7) but equalizer APO is the perfect form factor for them. Easy to install, standalone (my existing windows solution requires 4 different programs installed), works for playing everything. But, it lacks just a few things:

LR4 high and low pass filters
Shelving with Q
delay
ability to copy one channel to another (to create 4 driver channels from 2 stereo channels)

I've browsed the code, and don't mind contributing cody myself (none of these appear too difficult given the infrastructure provided).

If you are still interested in this topic, you could have a look at the capabilities of Equalizer APO 0.9. It supports the commands Delay and Copy. Shelving EQ filters with varying Q might be what the LSC/HSC filter types provide, as they accept variable values for the dB per octave. I don't know much about LR4 filters, but they might be implementable via the IIR filter type, where you can specify your own filter coefficients.
