Fourier analysis and reconstruction of audio signals
http://msp.ucsd.edu/techniques/latest/book-html/node172.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 …

2. Fourier Transform (FT) An audio signal is a complex signal composed of multiple ‘single-frequency sound waves’ which travel together as a disturbance(pressure-change) in the medium. When sound is recorded we only capture the resultant amplitudes of those multiple waves.

1. Filter the audio signal into frequency sub-bands 2. Determine the amount of masking for each band caused by nearby bands (in time and in freq) using the psychoacoustic model 3. If the signal is too small (or if it is \masked" by nearby frequen-cies), don’t encode it 4. Otherwise, determine the number of bits needed to represent

The "Fast Fourier Transform" (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal. FFTs are used for fault analysis, quality control, and condition monitoring of machines or systems.

Because the audio signal data is discrete, the Fast Fourier Transform (FFT) algorithm in MATLAB (on optimised implementation of the Discrete Fourier Transform) was used to analyze audio signals.7 The FFT function takes the form FFT(x,N) where x is the signal and Nthe number of frequency points.
