At its core, FFT is a mathematical algorithm that breaks down a signal into its constituent frequencies. Imagine a mixture of sounds – a guitar melody and a drumbeat. By using FFT, you can separate and analyze the guitar's frequency, the drum's frequency, and even the rate at which they change. This decomposition is done by representing the signal as a sum of sinusoids (sine waves) with different frequencies, amplitudes, and phases. The resulting frequency spectrum shows the distribution of energy across various frequencies, allowing for a deeper understanding of the signal.
