Abstract
Mask generation section generates an evaluating mask, indicative of a degree of dissonance with a target sound per each frequency along a frequency axis, by setting, for each of a plurality of peaks in spectra of the target sound, a dissonance function indicative of relationship between a frequency difference from the peak and a degree of dissonance with a component of the peak. Index calculation section collates spectra of an evaluated sound with the evaluating mask to thereby calculate a consonance index value indicative of a degree of consonance or dissonance between the target sound and the evaluated sound.
Claims12
A sound processing apparatus comprising:
- a mask generation section that generates an evaluating mask indicative of a degree of dissonance with a first sound per each frequency along a frequency axis, by setting, for each of a plurality of peaks in spectra of said first sound, a dissonance function indicative of relationship between a frequency difference from the peak and a degree of dissonance with a component of the peak;
- and
- an index calculation section that collates spectra of a second sound with the evaluating mask to thereby calculate a consonance index value indicative of a degree of consonance or dissonance between said first sound and said second sound.
A computer-implemented sound processing method comprising:
- generating an evaluating mask indicative of a degree of dissonance with a first sound per each frequency along a frequency axis, by setting, for each of a plurality of peaks in spectra of said first sound, a dissonance function indicative of relationship between a frequency difference from the peak and a degree of dissonance with a component of the peak;
- and
- collating spectra of a second sound with the evaluating mask to thereby calculate a consonance index value indicative of a degree of consonance or dissonance between said first sound and said second sound.
A computer-readable storage medium storing a program for causing a computer to perform a sound processing procedure, said sound processing procedure comprising:
- generating an evaluating mask indicative of a degree of dissonance with a first sound per each frequency along a frequency axis, by setting, for each of a plurality of peaks in spectra of said first sound, a dissonance function indicative of relationship between a frequency difference from the peak and a degree of dissonance with a component of the peak;
- and
- collating spectra of a second sound with the evaluating mask to thereby calculate a consonance index value indicative of a degree of consonance or dissonance between said first sound and said second sound.
