Patent ID: 7855334

Claim:
A music editing apparatus, comprising: a remix processing section which performs a remix process based on both meta data pre-generated corresponding to song data and containing at least time-based beat positions and a remix pattern file including data indicating an order and a manner for mixing together a plurality of songs; a synchronous reproduction controlling section which generates a master beat, sends the master beat to the remix processing section, and reproduces the plurality of songs with individual entries of the meta data corresponding to a remix process which the remix processing section designates based on the remix pattern file and the meta data; and a mixing section which mixes the songs reproduced by the synchronous reproduction controlling section, the synchronous reproduction controlling section comprising: a phase comparator which compares a phase of a beat synchronous signal generated from the meta data with that of the master beat signal; an integrating circuit which integrates a phase compared output of the phase comparator; and a correcting section which corrects a tempo based on an integrated output of the integrating circuit.
