Abstract
A signal processing method according to an embodiment of the present disclosure includes outputting a second sound signal by varying a level of a portion of a band of a first sound signal based on a second parameter corresponding to a displacement of each of a plurality of operators, the first sound signal being identified by a first parameter corresponding to the displacement, the second parameter being different from the first parameter.
Claims20
A signal processing device comprising:
- at least one memory storing executable instructions;
- and
- a processor that executes the executable instructions stored in the at least one memory to:
- obtain a first parameter corresponding to a displacement of an operator among a plurality of operators;
- identify a first sound signal based on the first parameter corresponding to the displacement of the operator;
- obtain a second parameter corresponding to the displacement of the operator among the plurality of operators, the second parameter being different from the first parameter;
- and
- cause a sound generator to generate a second sound signal by varying a level of a portion of a frequency band of the first sound signal, identified based on the first parameter corresponding to the displacement of the operator, based on the second parameter corresponding to the displacement of the operator.
