What Does STFT Stand For?

STFT stands for Short Time Fourier Transform

The Short Time Fourier Transform (STFT) is a mathematical technique used to analyze the frequency content of signals over time. It decomposes a signal into its constituent frequencies, providing a time-varying representation of its spectral content. By applying a windowing function to segments of the signal, the STFT captures both the time and frequency characteristics, making it valuable in various applications such as audio processing, speech analysis, and communications. This method enables the observation of how frequencies evolve over time, facilitating insights into non-stationary signals.
