What does the FFT give you?
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.
What is the benefit of FFT?
The FFT is used to process data throughout today's highly networked, digital world. It allows computers to efficiently calculate the different frequency components in time-varying signals—and also to reconstruct such signals from a set of frequency components.
How is Fourier transform used in music?
The Fourier transform is used to convert the time-domain input signal into a frequency-domain representation which can be analyzed for intensities of spe- cific pitches. The relationship between the pitches at a given time is then analyzed to determine the chord that is being played.
What is Fourier series used for music?
Throughout history, Fourier analysis was also used in music. This technique of analysis can be used to identify the naturally occurring harmonics of music. In essence, this is the basis for all musical composition. Clearly, math and music share attributes that can help in musical representation.
