Abstract
A tuning device is provided. The sound to be tuned is inputted by an input means while a reference sound is produced by an output means. At least two pitches are detected independently from a mixture of the sound to be tuned and the reference sound by a pitch detection means. Based on pitch information of the reference sound acquired by an acquiring means, the pitch of the sound to be tuned is extracted by a pitch extraction means from the at least two pitches detected by the pitch detection means. Information about the pitch of the sound to be tuned is displayed by a display means under control of a display control means. Therefore, the user can easily perform tuning on the sound to be tuned, based on the pitch information displayed by the display means, while listening to the reference sound and producing the sound to be tuned.
