Patent ID: 8873766

Claim:
A sound signal processor comprising: a connector configured to be connectable with an earphone; an input module configured to receive and process a first sound signal and a second sound signal as a plurality of sound signals corresponding to sound of a plurality of times output from the earphone, respectively, the first sound signal corresponding to a state in which the earphone is in close contact with a microphone, the second sound signal corresponding to a state in which a gap is provided between the earphone and the microphone; and a generator configured to generate, based on a target frequency characteristic and a combined frequency characteristic, correction data correcting a frequency characteristic of the earphone, the target frequency characteristic being set as a target, the combined frequency characteristic being a combination of first data and second data, the first data indicating a frequency characteristic of the first sound signal within a first frequency band lower than or equal to a reference, the second data indicating a frequency characteristic of the second sound signal within a second frequency band higher than the reference.
