Completely redesigned decoder!Turns your iPhone into a simple DTMF decoder. Simply hold the iPhone's microphone near to a clear source of DTMF tones (telephone "Touch Tones") and it will display the numbers being dialled. A row of LEDs indicate which frequencies are present in the signal - each LED corresponds to a single frequency.See it in action here:http://www.youtube.com/watch?v=UohQudD8rnA
