https://stackoverflow.com/questions/48500555/how-to-use-envelope-function-in-matlab
The following Matlab code generate a sound but it contain tak tak like sound which can be easily heard.Can someone removes this noise by using envelope function. Fs=44100; T=1/Fs; M=zeros(1,...
Signal envelope - MATLAB envelope - MathWorks
https://www.mathworks.com/help/signal/ref/envelope.html
[yupper,ylower] = envelope(x) returns the upper and lower envelopes of the input sequence, x, as the magnitude of its analytic signal. The analytic signal of x is found using the discrete Fourier transform as implemented in hilbert.The function initially removes the mean of x and adds it back after computing the envelopes. If x is a matrix, then envelope operates independently over …
MATLAB: ADSR envelope shaping on audio file – iTecTec

audio MATLAB matlab function. I'm trying to apply ADSR envelope shaping to an audio file as shown below. load handel y Fs;N = 1.5 * Fs;t = [ 0:N-1 ]/Fs;x = y/Fs;env = interp1 ( [ 0 0.1 0.3 1.1 1.5 ], [ 0 1 0.4 0.4 0 ], t);y = env .* x;sound (y,Fs) However, when performing the .* calculation, MATLAB freezes as the calculation is too large. Could ...

convolution - MATLAB- Add Envelope to Sound Signal ...
https://dsp.stackexchange.com/questions/64638/matlab-add-envelope-to-sound-signal
I’m in the process of making a convolution reverb and I’m trying to add an envelope to my impulse response signal and plot it in order to change the RT60 of my sound signal (Just a song). I’ve looked at the documentation on adding an envelope, but it doesn’t mention how to use the envelope for a signal that being sampled.
Envelope Extraction - MATLAB & Simulink
https://www.mathworks.com/help/signal/ug/envelope-extraction-using-the-analytic-signal.html
Envelope Extraction. This example shows how to extract the envelope of a signal. Create a double sideband amplitude-modulated signal. The carrier frequency is 1 kHz. The modulation frequency is 50 Hz. The modulation depth is 100%. The sample rate is 10 kHz. Extract the envelope using the hilbert function. The envelope is the magnitude of the ...
