Indicators for Stationary Sounds
The Indicators for stationary sounds profile computes the following indicators, including the loudness of stationary sounds:
Spectral Centroid (Hz) - The spectral centroid provides an initial physical, non-perception-based estimate of a sound's brightness or sharpness. This measure does not take into account psychoacoustic phenomena such as frequency masking. Cs, expressed in Hz is defined on the basis of the Intensity (I) of the various components in the frequency domain (f):
