Anatomy of a Spectrogram
NCVS Insights2024Vol. 2(4)
Abstract
This video provides a brief explanation of how spectrograms are constructed as a collection of individual spectra from consecutive points in time across a speech waveform. The difference between “narrow-band” and “wide-band” spectrograms is also explained based on choice analysis window duration. Three-dimensional animations of waveforms, spectra, and spectrograms are used throughout the video to demonstrate spectrographic representations of sound.
