Teensy to Arduino

I’m curious if there is any way to change over the teensy code from this project:

to be able to run on an Arduino instead? What would I have to change? would it work at all with an Uno (16MHz)?

Board: Teensy 3.1 CPU Speed: 48MHz or higher (by 32 bit)

...versus 16 Mhz by 8 bit. Over an order of magnitude difference in data processing. I'm going to go with "no".
