Conversion device, conversion method, and conversion program

A conversion device comprising:

• an acquisition unit that acquires a conversion source signal to be a source of a haptic signal;
• and
• a conversion unit that converts the conversion source signal acquired by the acquisition unit into an intermediate representation signal represented by at least one parameter, wherein
• the conversion unit,
• separates the conversion source signal into elements constituting the conversion source signal, and converts the separated signal into the intermediate representation signal, and
• in a case where the conversion source signal is an acoustic signal in which a plurality of instrument sounds is superimposed, separates the acoustic signal into individual instrument sounds and converts the separated signal into the intermediate representation signal.

A conversion device comprising:

• an acquisition unit that acquires a conversion source signal to be a source of a haptic signal;
• and
• a conversion unit that converts the conversion source signal acquired by the acquisition unit into an intermediate representation signal represented by at least one parameter, wherein
• the conversion unit
• converts the conversion source signal into the intermediate representation signal represented by the parameter corresponding to human perception, and
• converts the conversion source signal into the intermediate representation signal including, as the parameters, an attack being information representing a steep rise of an output value, a harmonic component being information having a fundamental frequency, a noise component being information not having a fundamental frequency, and information indicating a ratio between the harmonic component and the noise component.
