The document describes a C++ audio application class. It contains methods for setup, update, draw, audio input, and audio output. The audio output method generates audio using an ofxMaxi oscillator and mixes it to the left and right channels based on the mouse position. It can generate sine, saw, or pulse waves. The audio is processed in real-time from the microphone input.
