Abstract
When an instruction is provided for changing a characteristic of a set filter which includes a plurality of partial filters and forms a specified characteristic by combining a plurality of partial filters, a processor performs, as crossfading processing for a first filter and a second filter among the plurality of partial filters, fade-out processing of gradually decreasing a degree of contribution of the first filter to the characteristic and fade-in processing of gradually increasing a degree of contribution of the second filter to the characteristic. As a result, unnaturalness occurring at the time of changing filter characteristics is solved.

A filter characteristics changing device comprising:
- a set filter which includes a plurality of partial filters and forms a specified characteristic by combining the plurality of partial filters;
- and
- a processor which performs, as crossfading processing for a first filter and a second filter among the plurality of partial filters, fade-out processing of gradually decreasing a degree of contribution of the first filter to the characteristic and fade-in processing of gradually increasing a degree of contribution of the second filter to the characteristic, when an instruction is provided for changing the characteristic formed by the set filter.
A filter characteristics changing method, wherein a device performs, when an instruction is provided for changing a characteristic of a set filter which includes a plurality of partial filters and forms a specified characteristic by combining the plurality of partial filters, fade-out processing of gradually decreasing a degree of contribution of a first filter to the characteristic and fade-in processing of gradually increasing a degree of contribution of a second filter to the characteristic, as crossfading processing for the first filter and the second filter among the plurality of partial filters.
A non-transitory computer-readable storage medium having stored thereon a program that is executable by a computer to perform functions comprising:
- performing, when an instruction is provided for changing a characteristic of a set filter which includes a plurality of partial filters and forms a specified characteristic by combining the plurality of partial filters, fade-out processing of gradually decreasing a degree of contribution of a first filter to the characteristic and fade-in processing of gradually increasing a degree of contribution of a second filter to the characteristic, as crossfading processing for the first filter and the second filter among the plurality of partial filters.
