WebFFT is a high-resolution audio analysis tool available as an in-app purchase in AudioTools. It uses the Fast Fourier Transform (see below) to analyze incoming audio, and displays a very detailed graph of amplitude vs. frequency. NOTE: This information applies to the FFT module available within AudioTools. The standalone app is older, and does ... WebSep 28, 2024 · The output of a mathematical FFT will always be in the same units as the input. So if the input array to a software FFT is a series of voltage measurements, the output FFT array will be in units of Volts. For some FFT software functions, there is an additional step that converts the FFT output to dB and passes that back to the caller.
