Hi,
I am recording an audio. I have a start button and a stop button in GUI. When someone clicks start, the audio starts getting recorded.
Now, I want to enable the stop button only after x seconds. Where x could be 0.5 seconds, 1 seconds or whatever. How could I know that x seconds have passed and now its time to turn on the stop button.
Basically, I don't know how to start a clock and obtain its value. Can someone please help me with it?
Thank you.

function testtimebutton
figure
t = timer('TimerFcn','nan;','StopFcn',@endtimer, 'startdelay',... 2,'ExecutionMode','singleshot');
pbh1 = uicontrol(gcf,'Style','pushbutton','String','Start timer',...
'Position',[10 90 60 40],...
'callback',@stimer);
pbh2 = uicontrol(gcf,'Style','pushbutton','String','Button',...
'Position',[10 30 60 40],...
'enable','off','callback','disp(''You pressed the Button'')');
function endtimer(obj,event)
set(pbh2,'enable','on')
disp('timer stopped, Button enabled')
end
function stimer(obj,event)
start(t)
disp('timer started')
set(pbh2,'enable','off')
end
end
