Abstract: An acoustic system includes: a memory storing computer-executable instructions; a processor that implements the computer-executable instructions stored in the memory to execute a plurality of tasks. The plurality of tasks includes: a first signal acquiring task that acquires an acoustic signal and a first reverberation signal representing a waveform of reverberation sound corresponding to the acoustic signal; and a second signal processing task that generates a second reverberation signal by performing binaural processing and transaural processing on the first reverberation signal. The acoustic system further includes: a first speaker configured to emit sound corresponding to the acoustic signal; and a second speaker that is a dipole speaker, the second speaker being configured to emit reverberation sound corresponding to the second reverberation signal.

Abstract: An input device includes: an operation reception portion including a first group of operators and a second group of operators. In response to reception of a setting instruction, a setting process is executed to set a sound parameter for a setting target pair of operators among pairs of operators in the operation reception portion. Each of the pairs of operators includes a first operator in the first group and a second operator in the second group which are in a mutually symmetrical position relationship. The setting process includes: a first process of reflecting, for the setting target pair, the setting of the sound parameter for the first operator on the second operator; or a second process of replacing, for the setting target pair, the sound parameter that is set for the first operator and the sound parameter that is set for the second operator.

Abstract: A sound apparatus includes an acoustic device and a controller. The controller is configured to receive a setting of a trigger requirement. The controller is also configured to receive an action corresponding to the trigger requirement. The controller is also configured to associate the trigger requirement with the action. The controller is also configured to receive an operation to enable a movement that executes the action in a case in which the trigger requirement is satisfied. The controller is also configured to receive a selection of ON/OFF of auto sync that matches the action executed by the trigger requirement with a state of an acoustic device, before receiving the operation to enable the movement.

Abstract: An information processing method realized by a computer system includes acquiring a first sound field parameter representing a feature of a first sound field and a second sound field parameter representing a feature of a second sound field, and generating a third sound field parameter representing a feature of a third sound field by using the first sound field parameter and the second sound field parameter. The first sound field has first acoustic characteristics different from second acoustic characteristics of the second sound field. The third sound field has third acoustic characteristics different from the first acoustic characteristics and the second acoustic characteristics.
