How do I properly update this code.

How can I make this line of code that functioned properly in Matlab 2012 operate correctly in Matlab 2015b?

    time = get(handles.time_slider,'Value');
    x = wavrecord(time*8000,8000);
    set(handles.gender,'String','See the estimated gender here');
    set(handles.Fx1,'String', 'Fundamental Frequency');

Twice I've been directed to the following page but it hasn't helped.

The full code is attached.

How does this code not "operate correctly" in release R2015b? Does it throw an error (and if so what is the FULL text of the error message), does it issue a warning (and post the full text of the warning), etc?

function pushbutton_record_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton_record (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
global x;
time = get(handles.time_slider,'Value');

recorder = audiorecorder(8000,8,1);            %new
x = record(recorder, ceil(time*8000));         %changed

set(handles.gender,'String','See the estimated gender here');
set(handles.Fx1,'String', 'Fundamental Frequency');
guidata(hObject, handles);

Thank you for your help, but when I make the changes I get the following error:

    Error using audiorecorder/record
    Too many output arguments.

    Error in gui_speech_analysis>pushbutton_record_Callback (line 115)
    x = record(recorder, ceil(time*8000));

What does too many output arguments mean?
