WebJan 27, 2024 · An FFT file is an audio filter used by Adobe Audition, an audio production application. It saves settings that limit audio frequencies so that certain portions of the waveform can be isolated or pronounced, including the sample type and Fast Fourier Transform (FFT) information. WebFiltering a signal using FFT Filtering is a process in signal processing to remove some unwanted part of the signal within certain frequency range. There are low-pass filter, which tries to remove all the signal above certain cut-off frequency, and high-pass filter, which does the opposite.
