Spectrogram module for time-frequency analysis
This module provides functions for computing spectrograms of signals, which are visual representations of the spectrum of frequencies as they vary with time. It builds on the Short-Time Fourier Transform (STFT).
A spectrogram is useful for analyzing audio signals, vibration data, and other time-varying signals to understand how frequency content changes over time.
