Abstract: A distribution system includes a device control circuit that receives a first sound signal and a second sound signal that are related to a performance sound to be distributed. The device control circuit also receives meta-data indicating a type of the first sound signal and a type of the second sound signal. The device control circuit also receives sound environment data indicating a sound characteristic of a sound appliance. Based on a combination of the type of the first sound signal and the sound characteristic or a combination of the type of the second sound signal and the sound characteristic, the device control circuit controls the first sound signal or the second sound signal to be output to the sound appliance.

Abstract: A control device in one embodiment includes a first transmission unit, a first receiving unit, and a first generation unit. The first transmission unit is configured to transmit first performance data including contents of playing a keyboard instrument at a first communication base to a second communication base. The first receiving unit is configured to receive second performance data from the second communication base. The first generation unit is configured to generate a drive signal to produce a sound in accordance with the second performance data and output the drive signal to a sound generation device at the first communication base. At least one of the first performance data and the second performance data includes a key position signal indicating a key press amount on the keyboard instrument.

Abstract: A sound signal conversion device includes a supplier. The supplier supplies a periodic change to an input sound signal and outputs the sound signal to which the periodic change is supplied. The supplier includes a phase determiner that determines a phase at which the periodic change supplied to the sound signal starts based on initial phase information when receiving a start instruction for starting supply of the periodic change to the sound signal.

Abstract: Provided is a device 1 including: a signal processing unit 40 that applies a rotary speaker effect corresponding to a rotation speed value to a sound signal and control a tone color of the sound signal; and a control unit 10 that gradually changes, in response to a change command of the rotation speed value, the rotation speed value from a first speed to a second speed higher than the first speed with a first change curve having a first delay, and gradually changes control of the tone color from a first characteristic to a second characteristic that is stronger in the high frequency range than the first characteristic with a second change curve having a second delay shorter than the first delay.

Abstract: A distribution system includes an obtaining circuit, a determination circuit, a generation circuit, and a distribution circuit. The obtaining circuit obtains reaction information from a terminal device of a viewer of the content. The reaction information indicates a reaction of the viewer to the content. The determination circuit determines whether the reaction information is first reaction information or second reaction information. The first reaction information indicates a first reaction made by equal to or more than a predetermined number of viewers. The second reaction information is different from the first reaction information and indicates a second reaction made by less than the predetermined number of viewers. The generation circuit generates an audience sound in a case of the first reaction information. The distribution circuit transmits the audience sound to the plurality of terminal devices.
