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
Thanks

You can release the object to stop it.
release(myMic)
