MASKING SOUND DATA GENERATING DEVICE, METHOD FOR GENERATING MASKING SOUND DATA, AND MASKING SOUND DATA GENERATING SYSTEM
First Claim
1. A masking sound data generating device comprising:
- a source sound data obtaining portion that obtains source sound data which represents a sound used in a generation of masking sound data;
a speaker sound data obtaining portion that obtains speaker sound data which represents a voice of a speaker which is a masking target;
a band level specifying portion that specifies each level of two or more frequency bands in the speaker sound data; and
a band level setting portion that sets each level of two or more frequency bands in the source sound data, corresponding to the two or more frequency bands in the speaker sound data, in accordance with predetermined rules on the basis of the each level of the frequency bands in the speaker sound data specified by the band level specifying portion and that generates masking sound data which represents a masking sound,wherein the band level setting portion sets each level of at least two frequency bands among from the two or more frequency bands in the source sound data in accordance with the predetermined rules which are different to each other.
