Hello I will now demonstrate my voice recording application for the demo JM board. This circuit here is just a microphone amplifier. To start recording you turn the board on and select button 2 from the menu. This message tells you the file name that you’re about to record track 1. You press 1 to start recording. Then press 1, 2, 3. To stop recording you press 8. Now to play it back you select 1. As you can see track 1 is the file we’re about to play. Okay now, we can remove the ST card and put in computer. You can play back the wav file that I just recorded.
