The Corona audio system has advanced Open Audio Library (OpenAL) features. OpenAL is designed for the efficient rendering of multichannel three-dimensional positional audio. The general functionality of OpenAL is encoded in source objects, audio buffers, and a single listener. A source object contains a pointer to a buffer, the velocity, position and direction of the sound, and the intensity of the sound. Buffers contain audio data in the PCM format, either 8- or 16-bit, in either mono or stereo format. The listener object contains the velocity, position and direction of the listener, and the general gain applied to all sounds.
