1. An audio signal processing method performed by a non-mixer terminal excluding a capability to perform mixing processing of a plurality of input audio signals and being configured to communicate with a mixer configured to perform the mixing processing of the plurality of input audio signals, the mixer comprising a plurality of audio Input/Output (I/O) interfaces and a plurality of buses including (i) a monitor bus configured to send an audio signal to a monitor of an operator of the mixer and (ii) a bus different from the monitor bus, the audio signal processing method comprising:
receiving, by the non-mixer terminal excluding the capability to perform the mixing processing of the plurality of input audio signals, (i) a backtalk input instruction from a performer using the non-mixer terminal, the backtalk input instruction being an instruction that instructs the non-mixer terminal to send a backtalk signal to the mixer, and (ii) a specification of a bus among the plurality of buses of the mixer as a destination of the backtalk signal;
obtaining, by a microphone of the non-mixer terminal, voice information from the performer, the backtalk signal to be sent to the mixer corresponding to the voice information obtained by the microphone; and
sending the backtalk input instruction, the backtalk signal, and information indicating the destination of the backtalk signal to an audio I/O interface among the plurality of audio I/O interfaces of the mixer to thereby cause the mixer to output, in a case where the backtalk input instruction, the backtalk signal, and the information indicating the destination of the backtalk signal have been received from the non-mixer terminal, the backtalk signal corresponding to the voice information obtained by the microphone to the monitor bus of the mixer and to the specified bus among the plurality of buses of the mixer.
