Making it start & stop automatically? That's up to whatever audio playback hardware is installed in the display. It's nothing to do with the software that produces it. I'm sure there are off-the-shelf motion/proximity sensors that can trigger playback.

As far as how to create the audio file in Vegas/SoundForge/ACID? I don't see how it would be different from any other audio production. Make something that sounds nice and presents the information. I think the music should be very quiet, bland, and ignorable, otherwise people will have a hard time listening when several of them are playing back all at once. We humans have a good ability to pull out a single voice out of many and pay attention to it. Our ability to do so with music is much more limited.

Seems to me someone (Thomas Edison?) experimented with that many years ago - creating a chair that would talk to people when they sat down. Scared the bejeebers out of people !!

A guy I work with is experimenting with this new speaker that you only hear if you are directly in line front of it. That way you can have zones in a museum without suffering crosstalk from other exhibits. It apparenlty works by moving the air rather than a diaphragm. Pretty neat piece of equipment.

If you need the name of it, I can find out. It is for a similar application, we will have a sensor that detects when someone is in the area and will turn on.

Pioneer DVD-V7400 is one of many DVD players that can be triggered from
a contact closure to play a specific track. Simple motion detectors used by alarm
companies will provide a contact closure. The DB15 connector on the player
is where you connect it.

Great find LarryP. The Secret Sound reminds me of a scene from
the TV show "Get Smart".

You can use an RL circuit (like in a theremin instrument) or optical sensor as a trigger - several DIY projects around that in MI mags.

It would be interesting to use a MIDI trigger and an environment like Plogue Bidule to handle start/stop/fades that way... Hmmm...
