The Ultimate MACH Bar can optionally include an audio feature.   Two three-watt speakers are mounted inside the bar, similar to the speakers used in laptop computers.  Recordings or music (in WAV format) are uploaded to the MACH bar and can be played with the touch of a button.  Press the button to start/stop the audio recordings or cycle through them.

A configuration menu is built in to the user interface so that you can raise or lower the volume of the audio.
