Sound processing algorithms. How to file a guitar processor programmatically?

Question

Arduino

I decided to make my own guitar processor using arduino or raspberry. Where to dig, what to read, which foot to saw?
Thanks in advance.

Answer 1

Digital Signal Processing, but the arduina will not pull for sure without attachments.
Look also at a thing called "Pure Data" - there you can programmatically build processing.

Answer 2

The usual distortion - just take the exhaust from the ADC and cut off all values ​​​​above the threshold amplitude to the threshold.
