Benjamin	cf013ec88e	move OS-related #defines to .h file; speed improvements Combine two loops in stereo CIC computation into one for-loop. Add compiler optimization "unroll-loops" to isr if OS enabled. Speed improved from 113µs to 65µs per isr call for CIC interpolation filtering (Measured on Teensy 3.2 96MHz optimized).	8 vuotta sitten
