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.
