Abstract:

A method and system for producing an acoustic spatial projection by creating audio channels for producing an acoustic field by mixing, on a reflective surface, sounds associated with the audio channels is provided. In one embodiment, a method includes the step of using audio information to determining a set of audio channels. Each audio channel is associated with a sound source, such as one or more loudspeakers, and for a subset of the audio channels, the associated sound sources emit sound waves directed at a reflective surface prior to being received at a listening location. The method further includes steps of determining an acoustic response of a listening environment; steps of determining a delay to apply to one or more channels of the set of audio channels; and steps of determining a frequency compensation to apply to one or more channels of the audio channels.
