MATLAB: Having problem in placing a timer behind a togglebutton for audio recording!

Question

Dear All,

Actually I have a toggle button (togglebutton1). When I click on it first time, it starts recording. The next time I click it, it stops recording. This works fine with the following code:

function togglebutton1_Callback(hObject, eventdata, handles)
button_state = get(hObject,'Value');
if button_state == get(hObject,'Max')
recorder = audiorecorder(8000,8,1);
record(recorder);
set(handles.togglebutton1,'String','Stop Recording');
handles.recorder=recorder;
guidata(hObject,handles);
elseif button_state == get(hObject,'Min')
recorder=handles.recorder;
stop(recorder);
samples = getaudiodata(recorder,'uint8');
set(handles.togglebutton1,'String','Start Recording');
end

But what I want is that when you click on it for the first time, it starts recording. Then you can't press the button for 2 seconds. After 2 seconds, you can press the button to stop recording. This will make my recording duration of atleast 2 seconds. The recording could be greater than 2 seconds but the recording shouldn't be less than 2 seconds.

So, what I want is when you click on the togglebutton, it starts recording. Then the togglebutton gets disabled (enable=off) for 2 seconds. After atleast 2 seconds or more than 2 seconds recording, you can press the togglebutton again to stop recording.

What modifications would you suggest in the mentioned code?

Need it urgently.

Thank you.

Answer 1

%code to start recording and start record 
 set(hObject,'enable','off') 
 pause(2) 
 set(hObject,'enable','on') 
 %now the user can click again on the button
