Everyone is looking for a good fork, but nobody wants to pay for it!Finally I am pleased to offer a solution to this age-old problem: Fork-It!Fork-It feeds both microphone and accelerometer input into a real-time ring resonator.'Big words little man'Ok the gist is this. It behaves like a real tuning fork would. Or a real guitar string etc -- if you give the device a flick it will zing it appropriately. Or -- and this is the best one -- plug in headphones and try singing notes into it and get a sympathetic resonance. Sympathetic resonance huh?Yes - this feature is way cool. I don't think anyone's done it before on an iPhone. If you just sing the note it generates back into it it will come back out at you. But now try singing other notes, and you'll get DIFFERENT notes coming back out at you, as you hit the various harmonics.I uncovered this effect while working on a really radical system of conceptualising and learning music. This work is in full swing at the moment. Go over to my website and have a look if you're interested.Oh yeah and you can use it to tune instruments and stuff :p It is tuned to A3 -- that is an octave below concert pitch. I have deliberately dropped an octave so that it fits better in people's singing range, so you get more fun with experimenting with overtones.Have fun!PS I have also made a pro version that lets you tune to any note. It is called 'Fork'
