How to stop an audioDeviceReader recording

Question

Hyi everyone!

I would like to know if there is a way for stopping an "audioDeviceReader" recording, created using Audio Toolbox.

My code is:

%% Audio
hold on
n=2^11;
subplot(2,1,1)
myMic = audioDeviceReader(44100, n);
myVoice = myMic();
a = plot(2*myVoice);
xlim([0 n])
%% FFT
hold on
dt=1/myMic.SampleRate;
freqs=(abs(fft(myVoice)));
index = 0:n-1;
nu=index/(n*dt);
subplot(2,1,2)
b=plot(nu(1:n/2),abs(freqs(1:n/2)));
ylim([-3 3])
%% CYCLE
try
while 1
    myVoice = myMic();
   
   
    volume = max(abs(myVoice));
    a.YData = myVoice;
    subplot(2,1,2)
    mags = (abs(fft(myVoice)));%*dt/sqrt(2*pi));
    b=plot(nu(1:n/2),abs(mags(1:n/2)));
    axis([0 10000 0 2])
     drawnow
end
catch
    disp('a presto')
end
