Abstract

An out-of-head localization filter determination system according to this embodiment includes a microphone unit that is worn on a user's ear and picks up sounds output from an output unit, a measurement unit that measures a sound pickup signal output from the microphone unit, a data storage unit that stores first preset data related to spatial acoustic transfer characteristics and second preset data related to ear canal transfer characteristics in association with each other, a frequency characteristics acquisition unit that converts the sound pickup signal into a frequency domain and acquires frequency characteristics, an extreme value extraction unit that extracts a local maximum value and a local minimum value of the frequency characteristics, and an envelope calculation unit that calculates first envelope data and second envelope data by interpolating each of the local maximum value and the local minimum value.
