NOTE: This is nothing to do with 'movie clappers'. I've had one of those crazy ideas (yet again) for a piece of software but have no idea how to implement it. The premise is simple. I finish watching a movie on my Macbook or iMac from my bed late at night, but my Apple Remote is way out of reach, and I'm a lazy bones. Not to worry, I have just enough energy left to clap, which my Mac's built-in microphone hears, and proceeds to stand-by/shut down my system. I'm thinking a user-definable number/pattern of claps, with the ability to configure the noise threshold to not be set off by other sounds, as well as perhaps an option to define what action to take when the claps are detected. This could even possibly be broadened to include 'magic phrases' as I believe already exist in Apple's voice-recognition software. This idea, whilst just another great thing that most modern Macs should be capable of, is born out of both gimmicky fun, and also the fact that, watching movies through VLC, my iRemote's 'hold play to sleep system' function doesn't work for some reason.... Another reason for this is that, when 'sleeped' to standby, my Macbook always seems to wake up after an undisclosed amount of time. At least this way I could shut down my system from bed, no longer 'sleeping' it only to have it wake up and make that disk-initialisey noise about 25 minutes later and wake me up just as I'm falling asleep! 'Clap off - with iClapper' Slogan writes itself! Any clever coders fancy giving this a try?! OR does something like this already exist?
