can I write a program with python to recognise the sounds?

Question

How can I write a program that can read sound frequencies?
For example a guitar have 6 strings with 6 different sound frequencies...and it has a standard tuning and many different known tunes...
I want to run the program on mobile devices.

Answer 1

Good luck mate, I reckon you are going to be wanting more speed/power than js/python.

I think it's probably frequency & harmonics, probably looking for 2nd&3rd harmonic without too much of the higher waveforms.

There are several fantastic apps that listen in realtime, are you familiar with many of them?

Answer 2

If you mean sound analyser apps I know some of them(I'm playing guitar)...
I thought it was so simple like programming a simple calculator with different codes!
In fact, I want to write a real program for the first time and gradually expand my knowledge about programs that are made to work on sound.
Like a cubase

I want to learn this type of codes so that I can build my first metronome...
