Spectral Envelope Extraction with Matlab Implementation ...
https://www.mathworks.com/matlabcentral/fileexchange/66199-spectral-envelope-extraction-with-matlab-implementation
Reviews (1) Discussions (0) The present code is a Matlab function that provides envelope extraction of the amplitude spectrum of a given signal via shape-preserving piecewise cubic interpolation of the spectral peaks and moving average filtration of the result. The function is similar to (but not the same as) the Matlab function “envelope”.

Spectral Envelope Examples This section presents matlab code for computing spectral envelopes by the cepstral and linear prediction methods discussed above. The signal to be modeled is a synthetic ``ah'' vowel (as in ``father'') synthesized using three formants driven by a bandlimited impulse train [ 128 ].
How to find spectrum envelope from wav file

I am certain that MATLAB can do everything you want. You simply need to identify the algorithm you want to implement. Just now, those appear to be proprietary, so I am not certain how you will get them, but there may be a reference somewhere that describes them. I suggest you do a PubMed search. One of those references may provide you with the ...

The aspects of the audio we chose to visualize are the spectral envelope and the energy contained in the bass, mid-band, and treble ranges of the sound. 2. METHOD object, loading Implemented entirely in MATLAB, VisualizeR takes audio input either from an audio file specified or from a microphone input.
VisualizeR: Real-Time Audio Visualizer in MATLAB
http://www2.ece.rochester.edu/~zduan/teaching/ece472/projects/2016/Mateo_Gillie_poster.pdf
An audio visualizer is a graphic that evolves in time with audio playback, changing according to the characteristics of the sound. These characteristics can include volume, frequency spectrum, spectral envelope, onsets, and tempo. This project implements such an audio visualizer in MATLAB. Using MATLAB

D. Spectral Envelope Estimation using LPC Spectral envelope is a smooth curve that “envelopes” the graph of FFT magnitudes. It can be imagined as a string hanging of the peaks of FFT, giving an overall shape of the spectrum but not tracing the actual shape of the individual FFT bins. In fact, there are various ways to define and measure ...
