Teensy/Arduino cross compatibility?

[AVlantis]

So I just found out about the teensy and the wonderful audio GUI PJRC.com offers.

I actually just bought an arduino UNO, before I found out about the teensy.

Is it possible to generate code in the audio GUI and run it on my UNO?
What level of messing with it would I have to do?

The Audio library is heavily dependent upon the specific microcontrollers that are used in the different 3.x and 4.x boards, and doesn't support any 8 bit chips.

The Mozzi project does support 8 bit chips, I've never used it though: https://sensorium.github.io/Mozzi/

Good luck

Arduino Uno is woefully underpowered, only 8 bits and only 16 MHz. Uno also lacks DMA to efficiently move data between memory and audio hardware. It has no hope of running the audio library code.

Your best path is to get a Teensy 4.0 and audio shield and save the Uno for another project which doesn't need much CPU capability.

The integer performance of the T4 is about 300 times the Uno, the floating point is probably 4 to 5 orders of magnitude
faster on the T4... And the T4 has enough RAM for typical DSP tasks, the Uno does not really.
