Abstract: The audio signal processing apparatus includes at least one bus a network interface, a user interface, a display, and a processor. The network interface outputs an audio signal through a second plurality of audio channels through a network. The user interface receives an operation from a user. The processor receives, from a destination device to which the audio signal is output, information about the number of available output channels of the destination device, controls the display to display a virtual bus representing the output channels of the destination device, received information regarding the number of output channels, receives input setting of a correspondence relationship between the second plurality of audio channels of the audio signal and the virtual bus, generates setting information according to the received input setting, and sends the audio signal outputted from the network interface the audio signal and the setting information to the destination device.

Abstract: An audio signal processing method includes obtaining, performing, and outputting. The step of obtaining includes obtaining localization control information that determines an acoustic image localization position of an own terminal in an audio signal processing system. The step of performing includes performing localization processing on the audio signal of the own terminal, based on the obtained localization control information. The step of outputting includes outputting the audio signal on which the localization processing has been performed.

Abstract: An audio signal processing method includes providing a plurality of apparatuses and performing. The step of providing a plurality of apparatuses includes providing a plurality of sound collection apparatuses and a plurality of sound emission apparatuses corresponding to the plurality of sound collection apparatuses. The step of performing includes performing send level adjustment processing that sets a level of an audio signal of a sound collected by the plurality of sound collection apparatuses to a preset send level and sends the audio signal to the plurality of sound emission apparatuses. The send level adjustment processing changes a first send level to a minimum, the first send level being sent from a first sound collection apparatus that detects a talker voice, among the plurality of sound collection apparatuses, to a first sound emission apparatus closest to the first sound collection apparatus.
