Fourier analysis and reconstruction of audio signals 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 .

The process of decomposing a musical instrument sound or any other periodic function into its constituent sine or cosine waves is called Fourier analysis. You can characterize the sound wave in terms of the amplitudes of the constituent sine waves which make it up.

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

Fourier analysis is the study of how general functions can be decomposed into trigonometric or exponential functions with deflnite frequencies. There are two types of Fourier expansions: † Fourier series: If a (reasonably well-behaved) function is periodic, then it can be
