Abstract: A signal processing system including: a measurement device configured to acquire measurement data regarding a transfer characteristic; a first acquisition device configured to acquire a first audio signal; and a control device configured to be connected to each of the measurement device and the first acquisition device through a network, wherein the control device corrects the first audio signal on a basis of the measurement data acquired by the measurement device and generates a second audio signal.

Abstract: A signal processing system including a first control unit configured to calculate a transfer characteristic corresponding to a difference between a first audio signal and a second audio signal that is acquired by a first acquisition unit, the first acquisition unit being configured to acquire an audio signal, the second audio signal corresponding to the first audio signal that is reproduced by a first reproduction unit, the first reproduction unit being configured to reproduce an audio signal, and generate a fourth audio signal by convolving an inverse characteristic of the calculated transfer characteristic with a third audio signal that is acquired by a second acquisition unit.

Abstract: An audio device that is wearable on a user, the audio device including comprising a mic, wherein the mic is disposed at a position at which at least part of a vibration section of the mic is included inside an external auditory canal of the user and at an angle at which the vibration section has a vibration direction toward an inner wall of the external auditory canal when the audio device is worn by the user.

Abstract: An acoustic device includes: an imaging device configured to take a sample image of a space as a sound field and create an image data on the space based on the taken sample image; a sound collector configured to collect a sound generated in the space or to collect a previously-collected acoustic data therein; and a computation part configured to previously compute a plurality of parameters relevant to a coefficient of spatial acoustic filter corresponding to the sample image of the space and previously learn a sound field model of the space shown in the sample image. The computation part is configured to construct a sound field model of the sample image taken by the imaging device or of a previously-taken sample image, from the acoustic data collected by the sound collector, using the coefficient of spatial acoustic filter.
