On falstad.com/loadedstring one can try to get the Java-applet running (difficult on today's operating systems) which shows an instructive interactive simulation. | |

Basically, any periodic function can be expressed as a sum of sin() and cos() functions. A Discrete Fourier Transform is a computational tool that you can use to analyze a given wave form, and decompose it into that sum of sin() and cos() functions. | |

| Dec 5, 2017 at 16:26 | comment | added | CDCM | The oversimplified model would be Fourier analysis, which does exactly what you ask for: tells you which sine waves are in your signal. In reality however, automated chord recognition is not easy, as the kind of sounds we like do not consist of pure tones. | |
