摘要:
A music editing apparatus is provided that uses so-called time line meta data that describe a beat and melody structure of a song to automatically accomplishes an automatic DJ remix play with a low load. The apparatus also includes a synchronous reproduction controlling section which sends a master beat to the remix processing section and reproduces a plurality of songs corresponding to a remix process which the remix processing section designates corresponding to a remix pattern and the meta data and a mixing section which mixes the songs reproduced by the synchronous reproduction controlling section. The synchronous reproduction controlling section also includes a phase comparator which compares a phase of a beat synchronous signal generated from the meta data supplied from the remix processing section 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.

A music editing apparatus that can accomplish editing of superimposing or connecting whole or part of each of many songs such that their beats adjusted is provided. The music editing apparatus includes a remix processing section which performs a remix process based on both meta data that are pre-generated corresponding to song data and that contain at least a time-based beat position and a file for deciding a remix pattern; a synchronizing reproduction controlling section which generates a master beat, sends the master beat to the remix processing section, and reproduces a plurality of songs based on individual entries of the meta data according to the remix process that the remix processing section has designated corresponding to the remix pattern and the meta data; and a mixing section which mixes songs reproduced by the synchronizing reproduction controlling section. The remix processing section performs the remix process based on a remix pattern file structured as hierarchical layers each of which has a control parameter portion and a data entity portion.

A data reproduction apparatus includes a reproduction section that reproduces content, an identification information acquisition section that acquires information to identify the content, and a transmission section that transmits the information acquired in the identification information acquisition section and information unique to the data reproduction apparatus to an information distribution server on a network. A reception section receives information that the information distribution server has selected based on the information to identify the content and information unique to the data reproduction apparatus, and a control section presents the information received by the reception section in sync with the content to be reproduced by the reproduction section.
摘要:
A method of distributing mashup data for mashing up at least a first content and a second content. The method includes the step of distributing to a user, through a network, a data file having first data for dividing the first content and the second content into a plurality of blocks in accordance with individual contents, respectively, and second data indicating a disposition sequence for disposing the plurality of blocks in a predetermined sequence to create a new content.
摘要:
There are provided recording means for recording first data (12A) or (12B) used for dividing each of a first piece of content and a second piece of content into a plurality of blocks in accordance with each piece of contents and recording means (11A) or (11B) for recording second data indicating a sequence for arranging the plurality of blocks to create a new piece of content. The first piece of content and the second piece of content are mashed up using the first data and the second data, and a result of mashup processing is output. As a result, it is possible to mash up the first piece of content and the second piece of content without special knowledge.

摘要:
Upon receiving a digital audio signal recorded in a .wav file, a beat extraction processing unit 12 extracts coarse beat position information from this digital audio signal and outputs the result as metadata recorded in an .mty file. In addition, a beat alignment processing unit 13 aligns beat information of the metadata recorded in the .mty file and outputs the result as metadata recorded in a .may file. Beats of a rhythm of music are extracted highly accurately while reproducing a music signal of a musical tune.
