Learn how to control the device from the command line first to send/recieve data from the device. Then wrap that code in the GUI. They're two totally separate things, really...

Hi Kulbir,
I understand that you want to read, save, and plot real-time audio signals in MATLAB App Designer. Please follow the steps below:
- Start by designing your GUI in MATLAB's App Designer. You can refer the documentation.
- In the App Designer, create a callback function for the "Start" button. Inside the callback function, use the ‘audioDeviceReader’ function from the Audio System Toolbox to configure the audio device and start reading audio data.
- Add a "Stop" button to your GUI, along with its corresponding callback function. Inside the "Stop" button callback, stop the audio device to halt the data acquisition.
- If you want to save the acquired audio data, you can modify the code to write the data to a file using MATLAB's 'udiowrite'function. Create a file writer object and write the audio data inside the while loop.
- To update the GUI during real-time data acquisition, use the 'drawnow'function inside the while loop to ensure the GUI components are refreshed.
I hope this solves your query.
