FFT（或快速傅立叶变换）是用于图示化声音频谱组成的工具。对声音进行数学分析，并随时间动态变化，将其减少至一系列泛音成分。FFT的图形显示常表现为不同频段的振幅随时间的变化，提供被测声音信号清晰易读的，可视图形。
FFT (or Fast Fourier Transform) is a tool used to represent graphically the spectral constituents of a sound. The sound is mathematically analysed and is reduced to its various overtone components in their dynamic evolution over time. The graphic representation of an FFT usually plots the amplitudes of the frequency bands over time, offering a highly readable and visual representation of the sound being examined.
