iHearYou is an application that allows you to gain a musical representation of your surrounding sound via a traditional music staff or a standard guitar tablature. It supports accidentals, and allow you to set the beats per minute and the decibel sensitivity of the note pickup. It picks up notes in between the 3rd octave and the 6th octave.

At the moment it has no concept of different instruments, and treats every frequency as played by the same instrument, it also monitors the sound monophonically, meaning that it will fail to pick up the harmonics in chords, just the fundamental frequency of the chord.

Note to iPod Touch users: You will need the microphone device addition to use audio recording on this application.
