Hi everybody, I want to create a realtime pitch recogniser with Processing. How can I do this?  
Thanks.

Hello,

Start here:

> **[Sound \\ Libraries \\ Processing.org](https://processing.org/reference/libraries/sound/)**

And checkout the libraries that can be added from Processing:

You may want to do a search for “audio” also.

Thanks for the informations, they are very usefull, did you know if there is a way to extract all the harmonics of a sound? Like fourier coefficient for each pitch?  
Thanks

Hi,

Again, you can look at this thread talking about FFT :

- [Not sure how to work with Minim's FFT feature](https://discourse.processing.org/t/not-sure-how-to-work-with-minims-fft-feature/6638/2)

Specially this example with Minim :
