Just uploaded some Bench notes I am just thinking out loud and trying to chrystalyse my own thoughts as this is quite a complex excercise.
This video is an abridged video log of my bench notes as I progress with this build.

for Pduino I used this excellent tutorial

And for the Array loader Tabread patch I am indebted to Dr. Rafael Hernandez

For the impulse resopnses,

Thanks to David at Best Plugins

For more information on Convolution and the Fast Fourier Transform I recommend reading this web site.

katja's homepage on sinusoids,
complex numbers and modulation

The convolve~ object in Pd is not of my own invention I am indebted to its authors. As well as the Pd community where lots of other blogs papers videos etc have been referenced. I will write up a fully indexed instructable for the Tonefreqz Pduino pedal when it is completed and fully reference all of the source material. This is a brief update just for my Bench notes.

Current update on what all 3 of our pedals will have capablility to do.( Vis a Vid Standalone or networked)
Developing the guitar pedal concept for tonefreqhz guitar auditioning IR files. We have 3 controllers under development. Arduino ( in the video is useable with either wireless or USB connectivity to Pure Data convolve~patch on home computer. Raspberry pi and Beaglebone, pedals are available for standalone multi-effects pedal. The later run independant of home computer. RPi and Beagle are also running Pure Data Extended convolve~ , under the tonefreqhz guitar audition mode using raspberry Pi Debian, Raspbian, GNU/Linux. ( If you want something different just ask.)
Available to order or full instructables currently being written with source codes for download for Home Brew.
For serious Tone collectors everywhere, own every guitar in the shop!

Busy building my Pedal and dealing with the reference ground and PWM analog out theory etc, came across this video.

And highly recommend this blog entry and its links.

Great instructable sent me on the Highway to Ped(Hell) can't get enough ADC/DAC.

Update on the hardware side of this project.
Links to all the helpfull and informative information sourced so far.

I need to address the Resistor Values and also the reference ground voltage and also one of the capacitor values in this circuit.

I am encouraged with progress to date the next stage of the project is interfacing the guitar signal with Pure Data and adding additional controls as set out in the first video
so some more reading on Pduino.

These are really just bench notes again on progress to date still unresolved are the 5 way selector switch hack for the Pickup replacer selection so very much a work in progress.
