Default New project - ubuntu based lms

This is a new project of mine and i am looking for some help to make a howto for others like me.

Needs of the project:
multi channel processing (at least 2in 6 out - depends on ur soundcard)
Low latency.
web based gui ( or other viable remote control methods)
must be stable (hence the use of linux)
only open source software.
linear phase response (fft).
DRC.

Hardware: (dependent on your own HW this is mine)
AMD Quadcore
2g Ram
hoontech DSP2000 (8in 8out plus phantom mic etc).
emc8000 measurement mic.


Softwarefirst ideas atm)
Ubuntu Linux realtime (already using a rtos version of ubuntu for emc2)
brutefir - for filters low latency
virtual Fidelity(vFi) - provides a webpage via php and configure brutefir
Jack audio server - required for vFi
DRC - to create filters for brutefir
RoomEQ wizzard to generate IR for DRC


Uses for system: Fully PC based LMS including linear phase response filters(for XO/EQ), delays (small for aligning within a speaker box and large for seperate stacks),
compressors/limiters etc. ability to control system via network.



Reasons for software choices are as follows:

Realtime OS to help with latency.
BruteFIR seem to be quite efficient helping with latency
vFi seems to be a good start to using brutefir

At the moment i am looking at getting the brutefir / vFi side of things working before adding the extra functionality.

All suggestions are welcome ubuntu/linux OS is Not going to change so dont bother with this one
