Spectrogram

A spectrogram is a 2D representation of audio that plots frequency content over time, produced by sliding a Short-Time Fourier Transform (STFT) across the waveform. Think of it like a heatmap: the x-axis is time, the y-axis is frequency, and each cell's value is the energy…

The rest of “Spectrogram” is a premium feature: every concept in the library gets a precise, practitioner-focused write-up like this one, cross-linked straight from the paper summaries that use it.
