Why doesn't the audio recorder object execute the callback function?

I'm doing a program that detects hits in real time, up to a maximum of 10 hits. The problem I have is that the audiorecorder object does not execute its callback function during this recording. The only way I have succeeded in executing the program perfectly is by putting a debug on the next line at the beginning of the recording. I have tried to make the same effect by using the pause function in the following line, but it neither works. The result of making a tic-toc between these two lines is 0.019 seconds. Definitely neither of these two lines is working. I don't know if someone has faced a similar problem with these two functions and they know how to solve it.

recorder = audiorecorder(Fs,24,1);
set(recorder,'TimerPeriod',time_period,'TimerFcn',@(src,eventdata)hitDetection(src,eventdata,Fs,maxpeaks,MR,M,N));
tic
record(recorder)
pause(30)
toc

>> RecordingFunction

Elapsed time is 0.019214 seconds.

recordblocking() possibly?

Sergio - what is the value for time_period? How often are you expecting this callback to fire?

[Sergio Nieves Martínez]

The value for time_period is 0.1 seconds.

It seems to work for me in my test in R2019a on Mac:

Fs = 8000;
time_period = 2;
recorder = audiorecorder(Fs,24,1);
set(recorder,'TimerPeriod',time_period,'TimerFcn',@(src,eventdata)disp(datetime()));
tic
record(recorder)
pause(30)
toc
stop(recorder)
