Video Trigger 2009-01-10

Attach a camera and trigger sounds whenever occupancy is detected in six user-defined areas of the video image. You have complete control over the playback logic and signal routing. Surround is supported.

The answer often involves analog electronics, micro-controllers (like Arduino), or software (like Processing, pd, vvvv, Lily, Isadora, or MAX/MSP/Jitter). In the long-run these options provide much greater rewards, but if you have modest needs, Video Trigger is a painless way to get started. Video Trigger screenshot.

It works with any Quicktime video input device, like the Apple iSight, DV camcorders, and industrial cameras. Video Trigger can play up to six sound files (AIFF or WAV, 1-16 channels) through any Core Audio sound hardware (1-16 channels) with complete control over signal routing.
