[sdiy] The Owl: ARM fx pedal

[Terry Shultz]

Hi martin

I would like to suggest that any cortex m4 based part could be used. 

I was involved in the tone core pedal project and found that many folks had little dsp experience and were stumped on where to get examples that were relevant. The cmsis dsp libs are a good source point and perhaps one point to note, is that the Keil compiler was used to develop the library of dsp functions. So performance may differ greatly upon compiler selection.

Check out the audio weaver tool from dsp concepts. Dr. Beckmann owns this site and he was involved in the cmsis lib development for arm.

Overall, I would like to build upon this effort.

Regards,

Terry
