What does a spectral envelope represent?

Spectral envelope is the shape of the power spectrum of sound. It is an important cue for the identification of sound sources such as voices or instruments, and particular classes of sounds such as vowels.

What is frequency envelope?

In physics and engineering, the envelope of an oscillating signal is a smooth curve outlining its extremes. The envelope thus generalizes the concept of a constant amplitude into an instantaneous amplitude.

What is Hilbert envelope?

The envelope is the magnitude of the analytic signal computed by hilbert . Plot the envelope along with the original signal. Store the name-value pair arguments of the plot function in a cell array for later use.
