Musical instrument out of tune?
Audio Tuner is a free chromatic instrument tuner. Play your instrument into your computer's microphone and Audio Tuner will tell you the frequency being played. Select the note to tune it to and Audio Tuner will tell you if you are too flat or too sharp. This is applicable to guitars, ukuleles, pianos, and any other musical instrument you'd care to name.
