Abstract
A resonance sound signal generation method includes providing an instruction configured to generate a sound signal corresponding to a received pitch and producing a resonance sound signal. The method also includes receiving a multiple damper operation with respect to a plurality of pitches in a first pitch range. The method also includes providing an instruction configured to produce the resonance sound signal based on an additional sound relating to the multiple damper operation when the multiple damper operation is received.
Claims13
A resonance sound signal generation method comprising:
- providing, using a sound signal instructor, an instruction configured to generate a sound signal corresponding to a received pitch;
- producing, using a resonance sound producer, a resonance sound signal;
- receiving, using a multiple damper operation receiver, a multiple damper operation with respect to a plurality of pitches in a first pitch range;
- providing, using a resonance sound instructor, an instruction configured to produce, using a resonance sound signal generation apparatus, the resonance sound signal based on an additional sound relating to the multiple damper operation when the multiple damper operation is received, wherein
- an envelope waveform of the resonance sound signal is produced based on a sound signal of the additional sound, and the additional sound is in turn produced by carrying out waveform processing of a random noise;
- and
- outputting a simulated sound that is associated with a damper effect and the resonance sound signal, using a tone generator to thereby improve sound authenticity.
A resonance sound signal generation device comprising:
- a sound signal instructor that provides an instruction for generating a sound signal corresponding to a received pitch;
- a resonance sound producer that produces a resonance sound signal based on:
- i) string resonance, or ii) an ON operation of a damper pedal;
- a multiple damper operation receiver that receives a multiple damper operation with respect to a plurality of pitches in a first pitch range;
- and
- a resonance sound instructor that instructs the resonance sound producer to produce the resonance sound signal based on the ON operation of the damper pedal when the multiple damper operation is received in the multiple damper operation receiver, wherein
- an envelope waveform of the resonance sound signal is produced based on a sound signal of the additional sound, and the additional sound is in turn produced by carrying out waveform processing of a random noise;
- and
- a simulated sound that is associated with a damper effect and the resonance sound is generated using a tone generator to thereby improve sound authenticity.
A non-transitory computer readable storage medium storing a resonance sound signal generation program that causes a computer to execute a process of:
- providing, using a sound signal instructor, an instruction configured to generate a sound signal corresponding to a received pitch;
- producing, using a resonance sound producer, a resonance sound signal;
- receiving, using a multiple damper operation receiver, a multiple damper operation with respect to a plurality of pitches in a first pitch range;
- and
- providing, using a resonance sound instructor, an instruction configured to produce the resonance sound signal based on an additional sound relating to the multiple damper operation when the multiple damper operation is received, wherein
- an envelope waveform of the resonance sound signal is produced based on a sound signal of the additional sound, and the additional sound is in turn produced by carrying out waveform processing of a random noise;
- and
- outputting a simulated sound associated with a damper effect and the resonance sound signal, using a tone generator to thereby improve sound authenticity.
