Abstract
A CPU 41 acquires a string vibration signal in a case where a string picking operation is performed with respect to the stretched string 22, analyzes a frequency characteristic of the acquired string vibration signal, determines whether or not the analyzed frequency characteristic satisfies a predetermined condition, and changes a frequency characteristic of a musical sound generated in the connected sound source 45 depending on a case where it is determined that the predetermined condition is satisfied or determined that the predetermined condition is not satisfied.
Claims18
A musical sound control device, comprising:
- an acquisition unit that acquires a string vibration signal in a case where a string picking operation is performed with respect to a stretched string;
- an analysis unit that analyzes a frequency characteristic of the string vibration signal acquired by the acquisition unit;
- a determination unit that determines whether or not the analyzed frequency characteristic satisfies a condition;
- and
- a change unit that changes a frequency characteristic of a musical sound generated in a sound source according to a determination result by the determination unit.
A musical sound control method, comprising:
- acquiring a string vibration signal in a case where a string picking operation is performed with respect to a stretched string;
- analyzing a frequency characteristic of the acquired string vibration signal;
- determining whether or not the analyzed frequency characteristic satisfies a condition;
- and
- changing a frequency characteristic of a musical sound generated in a sound source depending on a case where it is determined that the predetermined condition is satisfied or determined that the predetermined condition is not satisfied.
A non-transitory storage medium storing a program configured to cause a computer to execute:
- an acquisition step of acquiring a string vibration signal in a case where a string picking operation is performed with respect to a stretched string;
- an analysis step of analyzing a frequency characteristic of the acquired string vibration signal;
- a determination step of determining whether or not the analyzed frequency characteristic satisfies a condition;
- and
- a change step of changing a frequency characteristic of a musical sound generated in a sound source depending on a result of the determination.
