Abstract: A method of processing sound includes arranging objects of a plurality of performers in a virtual space. The method also includes receiving a plurality of sound signals respectively corresponding to the plurality of performers. The method also includes obtaining, using a trained model, sound volume adjustment parameters respectively for the plurality of performers. The trained model is trained to learn a relationship between each sound signal, among the plurality of sound signals, that corresponds to each performer of the plurality of performers and each sound volume adjustment parameter, among the sound volume adjustment parameters, that corresponds to the each sound signal. The method also includes adjusting and mixing sound volumes respectively of the plurality of sound signals based on the sound volume adjustment parameters obtained using the trained model.

Abstract: A keyboard apparatus according to an embodiment includes a keyboard and a mutual capacitance proximity sensor. The keyboard includes a first key and a second key arranged in an array direction with respect to the first key. The proximity sensor includes a first electrode having a portion extending from at least a first area below the first key to a second area below the second key, a second electrode arranged in the first area, and a third electrode arranged in the second area. The proximity sensor is a mutual capacitance type sensor and is configured to use a change in capacitance between the first electrode and the second electrode and a change in capacitance between the first electrode and the third electrode.
