1. An audio system comprising:
- a virtual speaker position operation part, an adjustable position of a virtual speaker being given through the virtual speaker position operation part;
a sending unit for sending DSP parameter data that is prepared for each of sampling frequencies and includes data defining the adjustable position of the virtual speaker given through the virtual speaker position operation part;
a first memory for storing the DSP parameter data being sent from the sending unit;
audio signal terminals corresponding to sound sources, where audio signals from the sound sources are input through the audio signal terminals;
a selector for selecting a sound source from among the sound sources;
a sound field processor for sound field processing the sound signal from the selected sound source using one of the DSP parameter data corresponding to the sampling frequency of the sound source selected by the selector; and
an output terminal, the audio signal processed by the sound field processor being output through the output terminal,wherein the sound field processor processes the sound signal using the DSP parameter data stored in the first memory and the audio system further comprises a second memory which stores an initial state of the DSP parameter data, and wherein the sound field processor operates according to the DSP parameter data stored in the second memory when the DSP parameter data is missing in the first memory.

Abstract
Control data is stored in a first memory. Control data inputted from an external device is stored a second rewritable memory. A control section selects either one of the first and second memories and controls operation according to a control program using the control data stored in the memory selected. An image corresponding to control data is displayed on a display screen. Through the image, it is possible to select particular control data from a plurality of control data. The control data selected via the screen is sent to the second memory. Processing can be therefore executed to appropriately cope with requirements of the user.
