Abstract
An object of the present invention is to provide a processing device, a processing method, a reproducing method, and a program capable of performing appropriate processing. A processing device according to the present embodiment includes: an envelope computation unit computing an envelope for a frequency response of a sound pickup signal; a scale conversion unit generating scale converted data by performing scale conversion and data interpolation on frequency data of the envelope; a normalization factor computation unit dividing the scale converted data into a plurality of frequency bands, obtaining a characteristic value for each frequency band, and computing a normalization factor, based on the characteristic values; and a normalization unit, using the normalization factor, normalizing the sound pickup signal in the time domain.
