STFT is an acronym for Short Time Fourier Transform, a mathematical algorithm used to analyze and process signals. It calculates the Fourier Transform of a signal over small time intervals, allowing for detailed analysis of the frequency content of the signal. Some synonyms that can be used for STFT include signal processing, spectral analysis, digital signal processing, and time-frequency analysis. These terms are often used interchangeably within the field of engineering and signal processing as they all refer to the manipulation of signals over time and frequency domains. The STFT is a structured method for refining data into discrete components in the frequency domain.
