App Profile: ScopeTune

Tune your instrument, your ear, and your brain with a new, patent-pending approach to pitch. The 12 simultaneous o-scope displays are each locked to scan at the rate of a different note, and display live audio from the device's built-in microphone in your choice of wave or bar-density displays. When the note you're playing exactly matches a frequency, your waveform is frozen in place, in sync with that line's scan, but will drift left or right as your pitch drifts flat or sharp, going out of sync with the scan.

BENEFITS
• Instantly spot any note "frozen" while you play, and simultaneously see resonances with other pitches.
• See how your waveform reflects changes in your tone.
• Tune just/perfect intervals as waves from two notes line-up in sync with each other, and learn how to adjust a centered pitch to line-up with harmonics of another.
• Tune instruments which extend above or below the effective range of traditional tuners.
• Adjust scale and display-type to spot your waveform on a busy screen, even in noisy environments where some tuners have trouble "locking on" to your sound.
• Choose higher or lower octaves as suits your range, line-up to a desired frequency or precision level.

Best of all, gain insight into the physics of sound, and the interdependency of science and art.
