Patent ID: 7050869

Claim:
An audio system comprising setting means, display means, transfer means, a controller, and acoustic effect adding means, wherein: a type is selected among types of a parameter specifying acoustic effect through the setting means and a value of the parameter is set through the setting means; one of types of the parameter indicates an interval of time between a first peak of sound pressure observed at a sound receiving point and a second peak thereof; the type of the parameter selected and the value of the parameter set through the setting means are transferred to the acoustic effect adding means through the transfer means; the acoustic effect adding means adds acoustic effect to an inputted signal depending upon the type and the value of the parameter transferred through the transfer means; and the controller displays an image picture showing a sound source on the display means, and changes a size of the image picture depending upon the value of the parameter set through the setting means when the type of the parameter indicating an interval of time between a first peak of sound pressure observed at a sound receiving point and a second peak thereof is selected through the setting means.
