Abstract
A calibration system for calibrating multi-channel sound systems. The calibration system includes a method for calibrating a sound system that includes a plurality of loudspeakers. The method includes steps of mapping the plurality of loudspeakers into a virtual loudspeaker system representation displayable to a user, activating at least one calibration function that creates a calibration signal that is reproduced by one or more of the plurality of loudspeakers to produce a calibration sound perceivable by the user, modifying the virtual loudspeaker system representation to include a virtual calibration indicator that indicates a characteristic of the calibration signal, and adjusting the virtual calibration indicator based on a user input, wherein when the virtual calibration indicator is adjusted, a corresponding adjustment is made to the characteristic of the calibration signal until a selected calibration sound is achieved.
