Fourier analysis may be performed mathematically if the expression f(t) describing the waveform or COMPLEX TONE is known, or else by converting the sound to digital form by a computer which then ...

The application of this theorem to sound is known as FOURIER ANALYSIS and FOURIER SYNTHESIS. The theorem was developed by the French mathematician J.B. Fourier around 1800.
