Music reproducing system, rhythm analyzing method and storage medium

摘要

In a music reproducing system, each of characters is allocated in advance a favorite rhythm component and a peculiar figure expressing ability. A sound pressure data producing section produces sound pressure data for each of a plurality of frequency bands from musical data. A frequency band identifying section identifies the frequency band which beats a rhythm most. A rhythm estimating section derives a changing period of a sound pressure component in the sound pressure data at the identified frequency band and estimates a rhythm component based on the derived changing period. A character managing section cumulatively changes a figure expressing ability of a displayed character according to the matching degree between the estimated rhythm component and a favorite rhythm component of the displayed character. A display control section changes a display figure of the displayed character according to the figure expressing ability thereof while musical data is reproduced.
