In other words, Fourier series can be used to express a By using a Fourier transform, we can get the important parts of a sound, and only store those to end up with something that's pretty close to the original sound. Normally on a computer we store a wave as a series of points. Automate any workflow Packages. This is not intended to explain Fourier transform, per se, but time and frequency domains in the context of Fourier transforms. The Fourier Transform finds the set of cycle speeds, amplitudes and phases to match any time signal. (8.
