Ocarina for iPhone
Smule has unveiled its latest app for the iPhone, the Ocarina virtual instrument. As the user blows lightly on the device's microphone, the program analyzes the wind noise and tonguing to produce synthesized sounds. To further alter output, it tracks finger placement over four on-screen holes, as well as phone tilt. The combination of covered holes determines pitch, while tilting front and back adjusts vibrato depth, and tilting side-to-side changes the vibrato rate.
Ocarina also allows creations to be shared with other users. A globe view shows other players from around the world, and allows performances to be rated. Advanced options include choices for diatonic, minor or harmonic scales. The Ocarina app is available from iTunes for $1.
