Teensy 3.6 for 2 channel FFT processing. Use one or two

Will one 3.6 easily handle FFT processing for left and right channels or is it best to use two of them?

It depends of what your specs are

Excellent point, I am controlling 2,000 LEDs in a music visualization. I am leaning to using two Teensy's just to be on the safe side.
