In addition to displaying the frequencies, you can also generate sound using Spectral Eye; we have included a simple synthesizer, which will generate either a pure sine wave, or a sine wave with an additional frequency a fifth above.  Two instruments, such as a guitar or a trumpet, might play the same note -- what makes them sound different are the harmonic frequencies that combine to make the overall tone.  The core technology in Spectral Eye is part of our polyphonic pitch-to-MIDI app MIDImorphosis, which will let you use an ordinary guitar or other instrument to control MIDI synthesizers.  The version of Spectral Eye also includes MIDI; you can start a MIDI synthesizer, and then use the Spectral Eye display to trigger notes.  The sound that you hear is made up of vibrations at different frequencies.  of a synthesizer note changes, you can see different component frequencies rise and fall.  The resonant frequencies are what make different guitars sound unique.  On the Spectral Eye display, these frequencies fall into a line.  Eye different is the arrangement of the frequencies into a spiral, so that octaves line up as rays coming from the center.  Harmonies between the frequencies of multiple notes are what make chords sound interesting.  part of the screen to change the tone, and touch the main display and move in a clockwise or counterclockwise manner to change the pitch.  Spectral Eye will reveal these frequencies, so you can see what your sounds are made from.  Using a Fast Fourier transform, incoming sound is split into individual sine waves, which are then displayed on the screen.  You can see the structure clearly on the display as you make different kinds of sounds or play music.  When you pluck a string on a guitar, the string will vibrate at a root frequency, but also at a frequency that is twice that of the root, as well as a number of different multiples.  And if you're trying to pick out the notes to a song, you can watch the display to see where the notes land.  This technology is also part of Infinite Looper, our innovative MIDI looping app.  There are dozens of excellent synthesizers available; you can use this app to not only play them, but to see how their sounds are formed.  Spectral Eye is free, and will remain that way.  The `concert pitch' of A is a vibration at 440 cycles per second.  No nag screen.  If you like the app, we would very much appreciate a review in the app store.  One octave above this is a doubling to 880, and an octave below is 220.  Just good clean fun.  No pop-up ads.
