Matlab does not record audio
显示 更早的评论
I am working on the macOS Mojave 10.14.6, I am running the following code to record a short audio waveform:
recObj = audiorecorder(44100,16,1);
disp('Start speaking.');
recordblocking(recObj, 3);
disp('End of Recording.');
play(recObj);
y = getaudiodata(recObj);
plot(y)
Matlab does not record anything. The output of a plot(y) function is just a straight line y = 0. Moreover, Matlab doesn't ask for a permission to access microphone and I am not able to grant this permission in the system_preferences/privacy because the permission table doesn't contain Matlab. I tried opening the software from the terminal. Is there any way to configure it manually?

(Note to readers: this is a MacOS specific question that applies for Catalina, Mojave, and Big Sur.)

There is an issue with the preferences granted in Mac OS. As of now, the only workaround to the issue is to open MATLAB from the terminal without using the "open" command. For most users this will look as (doc):
/Applications/MATLAB_R2019b.app/bin/matlab
