Audio compression to compress recording

I am making an app with app designer in matlab the app will record from user I have done this part.

but it is required them to compress that recorderd audio I have made the button for the compress but I can't figure out the way to compress that audio

Here is the code for the recording.

function RecordButtonPushed(app, event)
            
            audioObject = audiorecorder;
            duration = 7;
            msgbox("Recording started");
            recordblocking(audioObject, duration);
            msgbox("Recording Stopped");
            
            assignin('base','audioObject',audioObject)
            
        end

That the handler for the recording button then I should compress that audio and play it.

So, anyone has an idea about how to compress the audio?

okh99 - do you want to reduce the sampling rate (and so reduce the total number of samples? or do you want to compress the audio recording file size?
