Hello, There is sound(y,Fs) function in Matlab to play array in audio device. In my case y is one dimensional array long 10000 and Fs = 2000. I can not use Audio Device Writer block in Simulink since it has minimum limitation of Fs = 8000. In Simulink I have to use User defined block with sound(y,Fs) function with coder.extrinsic('sound'), but function does not work in .exe file made from Simulink model (simulation model works). Question is how to play y array as sound? y array is made from 0 and 1, so if there is an event of interest there should be heard an impulse from the speaker.
function fcn(u)
coder.extrinsic('sound');
sound(u,2000);
This works in simulation but not in .exe. What is the substitute for sound() in Simulink? Best
