Feature request: integrate Q Library for unrivaled fast pitch detection

[mkoenings]

It would be awsome to be able to use this audio DSP library:
Cycfi Q library
It contains is the fastest pitch detection I know. I have used it successfully with a Daisy board, thanks to the great work found here:
Daisy Q
It can be used to create guitar synth apps, guitar to midi, , tuners, etc. It does not use much CPU power,which is a big plus.
Thanks!

What is the major difference between Pitch Detection and FFT ?
Did you do some measurements on the ESP32 or other microcontrollers ?
You could also try to use Faust which has a Pitch Tracker..

The author came up with a concept thar works on a bitstream level, ( bit, not byte :-) ).
He explains that in detail here. He needed that for his very sophisticated hex pickup guitar (Thor).
The main differenece is the speed, and the small footprint in terms of CPU, which is a bit of a problem with FFT. The Thor guitar uses 6 signals at the same time, whic are processed in "real"-time on one MCU, check out the sound samples if you find the time, its pretty amazing.
Thanks!
