Abstract
An object of the present disclosure is to provide a filter generation device and a filter generation method, capable of generating a filter suitable for out-of-head localization processing. A processing device according to an embodiment includes: a frequency characteristics acquisition unit configured to acquire frequency characteristics based on sound pickup signals; a level calculation unit configured to calculate a reference level in the frequency characteristics; a correction unit configured to correct the frequency characteristics so that the frequency characteristics fall within a predetermined level range including the reference level, and thereby calculate corrected characteristics; and a filter generation unit configured to generate a corrected filter based on the corrected characteristics.
