Audio device, sound processing method, sound processing program, sound output method, and sound output program

A sound processing method for use with an audio device, said method comprising:

• causing an audio signal to be output, the audio signal including a sound signal obtained through playback of content and a sound signal received from a communication partner device, the communication partner being a television receiver and being connected to the audio device by way of a network;
• generating an elimination signal obtained by eliminating a given sound signal from a microphone detection signal, which is the audio signal that is propagated and detected by a microphone;
• and
• causing, by a processor, the communication partner device to transmit the elimination signal,
• wherein another audio device is caused to transmit the audio signal, and
• wherein the elimination signal is generated on the basis of a sound delay amount pertaining to the another audio device, in which (i) a first value of the sound delay amount is initially set by the audio device and is utilized as the sound delay amount and (ii) the first value of the sound delay amount is replaced by a second value which is utilized as the sound delay amount when a new value of the sound delay amount is received from the another audio device and when the new value is determined to satisfy a predetermined condition.

A non-transitory computer readable medium having stored thereon a sound processing program which when executed causes a computer to function as an audio device to:

• cause an audio signal to be output, the audio signal including a sound signal obtained through playback of content and a sound signal received from a communication partner device, the communication partner being a television receiver and being connected to the audio device by way of a network,
• generate an elimination signal obtained by eliminating a given sound signal from a microphone detection signal, which is the audio signal that is propagated and detected by a microphone, and
• cause the communication partner device to transmit the elimination signal,
• wherein another audio device is caused to transmit the audio signal, and
• wherein the elimination signal is generated on the basis of a sound delay amount pertaining to the another audio device, in which (i) a first value of the sound delay amount is initially set by the audio device and is utilized as the sound delay amount and (ii) the first value of the sound delay amount is replaced by a second value which is utilized as the sound delay amount when a new value of the sound delay amount is received from the another audio device and when the new value is determined to satisfy a predetermined condition.
