Abstract
For example, a signal processing device configured to perform appropriate sound source separation processing is provided. A signal processing device includes: a downconverter configured to apply downsampling processing to a mixed sound signal in which sound source signals included in a high-frequency component higher than a predetermined frequency are mixed; a mask generation unit configured to generate a mask on the basis of a downsampling processing result provided by the downconverter; and a mask processing unit configured to apply the mask generated by the mask generation unit to the mixed sound signal.

A signal processing device comprising:
- a downconverter configured to apply downsampling processing to a mixed sound signal in which sound source signals included in a high-frequency component higher than a predetermined frequency are mixed;
- a mask generation unit configured to generate a mask on a basis of a downsampling processing result provided by the downconverter;
- and
- a mask processing unit configured to apply the mask generated by the mask generation unit to the mixed sound signal.
A signal processing method comprising:
- applying, by a downconverter, downsampling processing to a mixed sound signal in which sound source signals included in a high-frequency component higher than a predetermined frequency are mixed;
- generating, by a mask generation unit, a mask on a basis of a downsampling processing result provided by the downconverter;
- and
- applying, by a mask processing unit, the generated mask to the mixed sound signal.
A program configured to cause a computer to perform a signal processing method comprising:
- applying, by a downconverter, downsampling processing to a mixed sound signal in which sound source signals included in a high-frequency component higher than a predetermined frequency are mixed;
- generating, by a mask generation unit, a mask on a basis of a downsampling processing result provided by the downconverter;
- and
- applying, by a mask processing unit, the generated mask to the mixed sound signal.
