Using a very powerful wavelet algorithm and Arduino Due I implemented a library for pitch detection in real time.
Every 23 microSec arduino reads from A0 the audio signal so we have 43.470 Khz samplig rate (not 44100).
This is the first attempt, if you like post a comment or suggestions.
Here the library https://github.com/jackdev23/pitchdetector
Ciao Luca
hey. I'm working on a similar project. I'm running into a problem where after I used FFT, I don't know how to get the frequency component out.
But your link is dead, could you post a new one here? THank you
