Abstract

Scene data including a set of values of a plurality of signal processing parameters are stored in a memory. Adjusting values (offset values) of the parameters stored in a buffer are each modified only when a user has performed operation for modifying the value, and never modified automatically. Upon selection of new scene data, the individual parameters of the new scene data are read out from the memory, and the value of at least one of the read-out parameters is modified in accordance with the adjusting value. The values of the parameters, including the thus-modified value of the parameter, are collectively set in a signal processor, such as a mixer. If the modified parameter value is beyond a predetermined limit value, a value corresponding to the limit value is set in the processor, in which case the adjusting value stored in the buffer is not changed.

Claims6

Dependent claims

A state setting apparatus for audio mixing comprising:

a setting data storage section that stores a plurality of setting data representative of reference values of a plurality of parameters that are to be used for setting operating states of a signal processing circuit;
an adjusting value storage section that stores an adjusting value;
an adjusting value flag storage section that stores, for each of the parameters, an adjusting value flag indicating whether or not to use the adjusting value;
a setting data selection section that selects one item of said plurality of setting data stored in said setting data storage section;
a determination section that determines, for each of the parameters, whether or not to use the adjusting value with reference to the adjusting value flag stored in said adjusting value flag storage section;
a first operation setting section that, for each of the parameters for which said determination section has determined that the adjusting value should not be used, supplies the signal processing circuit with the reference value represented by the setting data selected by said setting data selection section;
a setting value calculation section that, for each of the parameters for which said determination section has determined that the adjusting value should be used, calculates a new setting value of the parameter on the basis of the reference value represented by the one item of setting data selected by said setting data selection section and the adjusting value stored in said adjusting value storage section;
and
a second operation setting section that supplies the signal processing circuit with the new setting value calculated by said setting value calculation section.
