补充你给我的代码，使在按第二个按钮播放音乐的同时显示波形和频谱

Sure! To display the waveform and spectrum while playing the audio when the second button is pressed, you can modify the `pushbutton2_Callback` function as follows:

function pushbutton2_Callback(hObject, eventdata, handles)
    % hObject    handle to pushbutton2 (see GCBO)
    % eventdata  reserved - to be defined in a future version of MATLAB
    % handles    structure with handles and user data (see GUIDATA)
    
    % Check if audio data and sample rate are available in handles structure
    if isfield(handles, 'audioData') && isfield(handles, 'sampleRate')
        % Play the audio using sound function
        sound(handles.audioData, handles.sampleRate);
        
        % Display waveform
        axes(handles.axes1);  % Assuming you have an axes component named 'axes1' in your GUI
        plot(handles.audioData);
        xlabel('Time');
        ylabel('Amplitude');
        title('Waveform');
        
        % Display spectrum
        axes(handles.axes2);  % Assuming you have an axes component named 'axes2' in your GUI
        spectrogram(handles.audioData, hamming(1024), 512, [], handles.sampleRate, 'yaxis');
        title('Spectrum');
    else
        disp('No audio data available');
    end
end

Make sure to replace `'axes1'` and `'axes2'` with the actual tag names of the axes components in your GUI where you want to display the waveform and spectrum.

With these modifications, when the second button is pressed, the audio will be played, and at the same time, the waveform will be displayed in `axes1` and the spectrogram will be displayed in `axes2`.
