filtering - MATLAB: How to demodulate a STREAMING …
https://stackoverflow.com/questions/50706760/matlab-how-to-demodulate-a-streaming-audio-file-rather-than-a-saved-audio-file
Now I would like to be able to demodulate (and display) the signal continuously as it streams in, without first having to store it. Any suggestions on how to modify the MATLAB code below? % FM Demodulate an Audio File June 5, 2018 %% Record the previously frequency-modulated signal for a few seconds. Fs = 44100; % Sample frequency of the sound wave …
