Device for the tempo determination and computer program for the tempo determination

摘要

A user is asked by using one section to the detection of knocking to beat positions to carry out a knocking, while the beginning of a waveform listen, are to be determined from the beat. If a section for the calculation of the fluctuation detects that the fluctuation of the knocking in a predetermined range, a beat - interval, the numerical value close to the tapping - tempo is selected from beat - interval - candidates, the from one section to the detection of tempo - candidates have been detected and a tapping - position at which the knocking is stable, is determined as the position of the start of beat. Knocking of the user for only a few beat makes it possible in the entire piece of music beats to determine the correct.
