How to make a sound recognition in Android? That is, if my application is open, this sound sounds and the application should react to it. Something like Shazam.

Hello. You compare the sound spectrum with the sound spectrum that you need to find using the correlation or autocorrelation function, I don’t remember exactly what is called, the point is that both sounds are represented as unit vectors in multidimensional (......) space and their largest similarity)))) In general, begin to delve into the decomposition of the spectrum using the Fourier theorem.)))
