In order to create a pronounced resonant peak the radius r needs close to 1, but remain less than one for stability. A radius of 0.85 was used in the simulation, if to large a value was chosen the filter would produce a whistling sound. To test the effect, 10 seconds of audio were recorded directly from a guitar using matlabs wavrecord function.
dsPic audio player ? | Microchip

0. Microchip has a sound recording/playback lib for the dsPIC. I believe it is designed for voice only. It uses a type of compression that can be done on the fly by the controller, however, it still takes I think something like 1 k/sec. So you would need an external chip to store audio of the length you want (not a really big problem).

https://electronics.stackexchange.com/questions/372898/microchip-dspic33-audio-dac-has-anyone-succeded-using-it-without-noise
The noise sounds white. Unfortunately I have no instruments to characterize it further. I have an old analog oscilloscope and an audio amplifier. EDIT 2: Here there is the waveform, the spectrogram and the FFT of the background noise with and without the audio passing through the MCU. This was recorded using a cellphone recording the line input ...

https://dsp.stackexchange.com/questions/13142/digital-distortion-effect-algorithm
$\begingroup$ Distortion is a very vague term which describes any (usually unwanted) transformation that alters the signal. Guitar distortion is achieved by many different processes - clipping, rectification, overloading - depending on the kind of pedal/amp in which it happens - there is no single "true" formula...

DsPIC includes a 12-bit ADC and a 16-bit DAC. The first sampling is done at 12-bit resolution and 32KHz, but after that, the entire internal process is 16-bit, and the final output is actually 16-bit / 32KHz. 12-bit / 32 KHz is typical for the 1980’s rack studio delay processor. Super clean or non-sterile sound quality is very good.
