SonicDemo is one of several iOS demo apps for the Philadelphia Game Lab's open source 3D Audio library, Sonic. As with all Sonic apps, SonicDemo requires headphones.
In contrast with the other demo apps, SonicDemo doesn't do a whole lot. It is meant more as a starting point for developing other iOS apps with Sonic, but if you'd rather start from scratch you can follow the Sonic setup instructions. To use SonicDemo as a starting point for your own iOS Sonic app, just fork or clone it.
