How do i call the recorded audio into another push button and compress it in GUI.

I want to call this 'myrec1' in pushbutton 2 and compress it. the resultant is to be displayed on axes2.

Muhammad - you can either extract the data from the plot (from handles.axes1) or just save the recorded data to the handles object in the first push button callback. Try

function pushbutton1_Callback(hObject, eventdata, handles)
% your code from above

% save to the handles object
handles.myrec1 = myrec1
guidata(hObject, handles); % <--- You need this to save the updated handles structure

Your second callback would look something like

function pushbutton1_Callback(hObject, eventdata, handles)
if isfield(handles, 'myrec1')
    % compress the data
    audioData = handles.myrec1;
  
    % plot
end
