Read in an audio file, calculate the slope using default parameters, and then plot the results. [audioIn,fs] = audioread( 'Counting-16-44p1-mono-15secs.wav' ); slope = spectralSlope(audioIn,fs); t = linspace(0,size(audioIn,1)/fs,size(slope,1)); plot(t,slope) xlabel( 'Time (s)' ) ylabel( 'Slope' )
Spectral slope - HandWiki
https://handwiki.org/wiki/Spectral_slope
In astrophysicsand planetary science, spectral slope, also called spectral gradient, is a measure of dependence of the reflectanceon the wavelength. In digital signal processing, it is a measure of how quickly the spectrum of an audio sound tails off towards the high frequencies, calculated using a linear regression. [1]

Many spectrum tools default to 3dB per octave, as that renders a plot more associated with classic pop sounds, while many of today’s lush music productions reputedly give a flatter frequency visualization with the spectral analyzer slope set to 4.5 dB per octave. If you’re using a spectrograph to guide your mixing decisions, in part you want to decide whether you …
