How to use recordblocking for an infinite interval?

I need to record an audio until I stop the recording (using a button or something), do you know how to do it?

@Marie Kate Palau I don't think you want to use recordblocking since that would prevent you from stopping the recording after an unknown period of time. Try using record instead. I'm assuming that you have a GUI to start and stop the recording?

Thanks for the advice of using record, do you know how can I use it with a loop or something to stop the recording? I was thinking of using GUI but I wanted to find another way to stop the record, maybe using "break" or something like that

So long as you have access to the audiorecord object, then you should be able to just stop it. For example, from the MATLAB command line, try doing

>> myRecorder = audiorecorder;
>> record(myRecorder);

Now you can start talking, singing, etc. And when you are ready to stop the recording, just do

>> stop(myRecorder);

I'm not sure if I'm using it the way it should be, but it doesn't work as I expected, don't know if can you please check it just to notice what I'm doing wrong

clearvars;
myRecorder = audiorecorder(1000,16,1); % Crea el elemento de MATLAB para grabar audio
disp ("Hable ahora");
record(myRecorder);
% Graba durante 2 segundos
disp("Deje de hablar");
stop(myRecorder);
play(myRecorder);
audioArray=getaudiodata(myRecorder);
% Pone los datos de la grabación en un vector de MATLAB
plot(audioArray)
title('Visualizacion del Sonido','FontSize',16,'Interpreter','latex')
xlabel('Tiempo ($mseg$)','FontSize',14,'Interpreter','latex')
ylabel('Amplitud','FontSize',14,'Interpreter','latex')
set(gcf,'color','w')
set(gca,'FontSize',12,'TickLabelInterpreter','latex')
grid on

@Marie Kate Palau

Your code is stopping recording immediately after sending out the message 'Deje de hablar' .

Consider something like

record(myRecorder);
% Graba durante 2 segundos
menu("Deje de hablar", "para de grabar");
stop(myRecorder);
