Abstract: An audio signal processing device includes a memory; and a processor configured to execute receiving a command to determine one set of parameters from among parameters calculated according to positions at which a sound is localized, the positions being set relative to positions of audio output devices; and processing a sound to be output from the audio output devices, by using the one set of parameters determined based on the received command.

Abstract: An acoustic system includes an audio output device configured to output a sound to a listener being still at least for a predetermined period of time, and an acoustic control device configured to perform signal processing for localizing, at a specific part of the listener, the sound that is output through the audio output device, wherein the audio output device is installed above the specific part of the listener.

Abstract: A signal processing device includes one or more filter processors that perform sound localization processing of an input acoustic signal and generate output signals; a coefficient setter that sets, for the filter processors, a plurality of filter coefficients for use in the filter processors; an output data selector that selects, out of the output signals subjected to the sound localization processing by the filter processors, output signals to be output to a left speaker and a right speaker; a time measurer that monitors a time for switching the output signals; and a controller that causes the output data selector to select the output signals in accordance with the time for switching the output signals. The plurality of filter coefficients include filter coefficients generated under a plurality of hearing conditions.
