Abstract

A content data generating device includes a first storage configured to store content data including at least either video information or audio information, a second storage configured to store variation data representing change of a parameter on the content data, a designator configured to designate a portion of the variation data, and a content data generator configured to process the content data according to a value of the parameter of the portion of the variation data designated by the designator to generate processed content data.

First claim

What is claimed is:

1. A content data generating device comprising:
a first storage configured to store content data including at least either video information or audio information;
a second storage configured to store variation data representing change of a parameter on the content data;
a designator configured to designate a portion of the variation data; and
a content data generator configured to process the content data according to a value of the parameter of the portion of the variation data designated by the designator to generate processed content data,
wherein the content data is waveform data representing a waveform of a sound signal;
wherein the variation data is a data sequence is constituted by plural segment defining data for defining plural segments respectively when the plural segments are cut out from the waveform data,
wherein the designator designates plural adjacent segment defining data of the plural segment defining data constituting the data sequence, and
wherein the content data generator cuts out the plural segments from the waveform data according to the designated plural segment defining data, cross-fades the plural segments to generate waveform data, and writes the generated waveform data to the first storage.

2. The content data generating device according to claim 1 , wherein the designator selects the plural adjacent segment defining data from the plural segment defining data constituting the data sequence and repeatedly designates a data sequence constituted by the selected plural segment defining data.

3. The content data generating device according to claim 1 , wherein a length of at least one of the plural segments is different from a cycle of a fundamental tone of the content data stored in the first storage.

4. The content data generating device according to claim 1 , wherein lengths of the plural segments are decreased or increased along in a time axis of the waveform data gradually.

5. The content data generating device according to claim 1 , wherein the content data generator mixes the generated waveform data and waveform data received from a FM tone generator and writes the mixed waveform data to the first storage.

6. A content data generating method of a content data generating device including a first storage storing content data including at least either video information or audio information and a second storage storing variation data representing change of a parameter on the content data, the content data generating method comprising the steps of:
designating a portion of the variation data; and
processing the content data according to a value of the parameter of the portion of the variation data designated by the designator to generate processed content data,
wherein the content data is waveform data representing a waveform of a sound signal;
wherein the variation data is a data sequence is constituted by plural segment defining data for defining plural segments respectively when the plural segments are cut out from the waveform data,
wherein the designator designates plural adjacent segment defining data of the plural segment defining data constituting the data sequence, and
wherein the content data generator cuts out the plural segments from the waveform data according to the designated plural segment defining data, cross-fades the plural segments to generate waveform data, and writes the generated waveform data to the first storage.

7. The method according to claim 6 , wherein the processing step mixes the generated waveform data and waveform data received from a FM tone generator and writes the mixed waveform data to the first storage.
