Abstract
A sound apparatus includes: an acquisition unit that acquires multichannel audio data; a transmission unit that transmits the multichannel audio data to a conversion apparatus via a communication network; a reception unit that receives from the conversion apparatus, two-channel audio data generated by converting the multichannel audio data into a virtual sound source by the conversion apparatus; and an audio reproduction unit that drives two loudspeakers according to the two-channel audio data.
Claims9
A communication method for a communication system, the communication system including:
- a sound apparatus connected with two loudspeakers and connected to a communication network;
- and a conversion apparatus connected to the communication network, the communication method comprising:
- acquiring multichannel audio data including pieces of audio data of a left front channel, a right front channel, and a first channel;
- transmitting the multichannel audio data from the sound apparatus to the conversion apparatus via the communication network;
- converting audio data of at least the first channel of the multichannel audio data into a virtual sound source by using a head-related transfer function;
- superimposing the converted audio data of at least the first channel on the left front channel and the right front channel to generate two-channel audio data;
- transmitting the two-channel audio data from the conversion apparatus to the sound apparatus via the communication network;
- and
- driving the two loudspeakers according to the two-channel audio data.
