Patent ID: 8761914

Claim:
An audio apparatus comprising: a parameter control; at least one memory device having a current memory area, a setting data memory area, and a list memory area; a microprocessor programmed to execute: a current memory storing task that stores, in the current memory area, a parameter set comprising a plurality of parameters; a parameter changing task that changes a value of a parameter, among the plurality of parameters of the parameter set stored in the current memory area, in accordance with a user manipulation of the parameter control; a setting data storing task that stores, in the setting data memory area, a plurality of setting data sets, each having a unique ID; a list memory storing task that stores, in the list memory area, the plurality of IDs identifying the plurality of setting data sets stored in the setting data memory area in association with data numbers contained in the setting data sets, respectively; a storing task that responds to a user request for storing with a specified data number, wherein the storing task creates, in a case where an ID associated with the specified data number is not stored in the list memory area, a unique ID and stores the parameter set stored in the current memory area in the setting data memory area as a setting data set identified by the created unique ID, as well as storing the created unique ID in the list memory area in association with the setting data set and identified by the ID with the parameter set stored in the current memory area; and a call task that responds to a user call request with a data number being specified, wherein the call task reads, in a case where an ID associated with the specified data number is stored in the list memory area, a setting data set identified by the ID from the setting data memory area and overwrites the parameter set stored in the current memory area with the read setting data set; and an audio signal processor connected to the microprocessor and that processes an input audio signal in accordance with the parameter set stored in the storage device and outputting the processed audio signal.
