Abstract
A beat timing generation device including a generation unit for generating, from data of music that has been input, information of timings on which a beat of the music depends and a plurality of pieces of intensity data indicating a power at the timings; a calculation unit for calculating a period and a phase of the beat of the music using the plurality of pieces of intensity data; and a detection unit for detecting a beat generation timing on a basis of the period and the phase of the beat.
Claims20
A beat timing generation device comprising:
- a processor, configured to:
- generate, from data of music that has been input, information of a plurality of timings on which a beat of the music depends and a plurality of pieces of intensity data indicating a power at each of the plurality of timings;
- calculate a period and a phase of the beat of the music by using the plurality of pieces of intensity data, wherein a beats per minute (BPM) for the plurality of pieces of intensity data is set on a basis of the timings indicated by the plurality of pieces of intensity data, one period of the BPM is calculated as the period of the beat, and a relative position of a beat generation timing is calculated with respect to a periodic wave indicating the BPM as the phase of the beat;
- and
- detect the beat generation timing on a basis of the period and the phase of the beat.

A beat timing generation device comprising:
- a processor, configured to:
- generate, from data of music that has been input, information of a plurality of timings on which a beat of the music depends and a plurality of pieces of intensity data indicating a power at each of the plurality of timings, wherein each of the plurality of pieces of intensity data corresponds to data indicating the sum of the powers as the intensity data when the data indicating the sum of the powers being a maximum value;
- calculate a period and a phase of the beat of the music by using the plurality of pieces of intensity data;
- and
- detect a beat generation timing on a basis of the period and the phase of the beat.
