– what is the fast Fourier transform in relation to audio processing?
In: 7
The fast Fourier transform is a tool that helps people who work with sound to understand what kind of sounds are in a piece of music or other audio recording. It does this by breaking down the sound into tiny parts and figuring out what kinds of sound frequencies are present in each part.
This is helpful because different frequencies of sound can make a big difference in how a piece of music sounds. For example, high frequencies can make a sound seem bright or sharp, while low frequencies can make it seem deep or booming.
The FFT is like a special microscope that lets us look at a sound and see all of its different parts, so we can understand it better and do cool things with it, like making it sound different or removing unwanted noise.
