AudioDSP boost effect based on the pedalSHIELD.
Boost.ino is a simple clean boost/volume control example from the pedalSHIELD examples. The pushbuttons control the output volume up and down.
- the main loop sets the effect on/off indicator (LED on pin 13)
- input read/output write is handled in the Timer 1 interrupt service routine
This example uses a private AudioDspDriver library that contains my refactoring of the core algorithms for driving the board. I may split this out as a stand-alone library at some point.
