  • Patent number: 10733900
    Abstract: Tuning information is calculated based on input sounds. A tuning estimating apparatus includes an input sound acquirer for acquiring input sounds, a pitch calculator for calculating pitches of the input sounds acquired by the input sound acquirer, and a tuning value calculator for calculating a tuning value representing an offset between a tuning reference position serving as a reference for tuning and a reference position on a first distribution of the pitches calculated by the pitch calculator, based on a peak of the first distribution. The tuning value calculator calculates the tuning value based on the positional relationship of a periodic peak group of the first distribution.

  • Patent number: 10726821
    Abstract: A performance assistance apparatus includes a sound generator circuit and a processor. In response to detection of a sound generation timing, the processor determines whether or not the sound indicated by the user performance information matches the sound designated by the model performance information in association with the sound generation timing. Based on determination that the sound indicated by the user performance information does not match the sound designated by the model performance information, the processor causes the sound generator to audibly generate an assist sound relating to the sound designated by the model performance information.
