barkSpecSpread~

The barkSpecSpread~ object calculates the spread of an audio signal's Bark spectrum, indicating the concentration of energy around its centroid. It outputs this value in Barks, where a low spread signifies concentrated energy (like a sinusoid) and a high spread indicates dispersed energy (like noise). This descriptor is useful for analyzing timbre and can serve as a feature for real-time audio classification systems.
