WaveShaper by Damien Di Fede is an audio synthesis app that lets you control a sound wave on an iPad. Use two fingers to control four parameters in real-time shaping and deforming included 20 audio files or add your own audio files using the Documents folder in iTunes. There are also 8 preset slots for storing control point positions, touch-and-slide on the presets to scrub between them and you can share your recordings on SoundCloud from within the app.
WaveShaper is a mixture of openFrameworks, UIKit, and Minim for C++. You can read more about the making on Damien’s blog.
