In section 6 we discuss the speed of the discrete Fourier transform and introduce the fast Fourier transform. The fast Fourier transform is then utilized in MATLAB to construct a chromagram or pitch-intensity plot of an audio le. 2 Introduction to Music Theory Before we delve into the mathematics behind chord recognition, it is important for

Fourier analysis and reconstruction of audio signals

http://msp.ucsd.edu/techniques/v0.08/book-html/node166.html

Fourier analysis can sometimes be used to resolve the component sinusoids in an audio signal. Even when it can't go that far, it can separate a signal into frequency regions, in the sense that for each , the th point of the Fourier transform would be affected only by components close to the nominal frequency . This suggests many interesting operations we could perform on a signal …

The Fourier transform is always positive. The magnitude spectrum of a real signal is symmetric about the y-axis. The distance between two neighboring frequency bins (in Hz) increases as the DFT block block length increases. The real part of the FT is always positive.
