A more general form of analysis for transferring a time-domain signal to the frequency domain is called the Fourier transform. Compare: FOURIER SYNTHESIS, HELMHOLTZ RESONATOR, LAW OF SUPERPOSITION, ...

He’s using a Fast Fourier Transform routine crafted in C ... He utilizes the properties of an LM386 to move the input signals from a range of -0.5V to +0.5V into a very ADC friendly range ...
