Music edit device and music edit method

A music editing method, comprising:

• performing 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;
• generating a master beat, sending the master beat to the remix processing section, and reproducing the plurality of songs corresponding to a remix process which the remix processing section designates based on the remix pattern file and the meta data;
• and
• mixing the songs reproduced by the synchronous reproduction controlling section,
• wherein reproducing the plurality of songs corresponding to the remix process further comprises:
• comparing a phase of a beat synchronous signal generated from the meta data supplied from the remix processing step with a phase of the master beat signal to generate a phase compared output;
• integrating the phase compared output to generate an integrated output;
• and
• correcting a tempo based on the integrated output.

A music editing apparatus, comprising:

• a remix processing means for performing 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 means for generating a master beat, sends the master beat to the remix processing means, and reproduces the plurality of songs with individual entries of the meta data corresponding to a remix process which the remix processing means designates based on the remix pattern file and the meta data;
• and
• a mixing means for mixing together the plurality of songs reproduced by the synchronous reproduction controlling means,
• the synchronous reproduction controlling means 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.
