Exploring the Short-Time Fourier Transform: Analyzing Time-Varying Audio Signals | by Ong Zhi Xuan | Medium
Gabriel Peyré on X: "The spectrogram (aka short time Fourier transform) reveals the geometry of sounds. Evolving harmonics of a birds singing become smooth curves. Sounds are intrinsically (at least) 2-D (time -frequency).
