    An off-the-shelf possibility for audio is a PACT  Timer. Handy for 
figuring out how fast your machine guns are running:

    Easy enough to use a remote microphone or just  record and playback the 
sound, if you're worried about hurting digital  equipment. Or just stand back. 
Heck, last time I ran my SISG coil I could hear  the roar of the secondary 
arcs echoing off the houses around the corner 100  yards away. So reflections and 
false triggers from them might be a  concern.
