摘要： Disclosed are an audio apparatus and an audio providing method thereof. The audio providing method includes receiving an audio signal including a plurality of channels, applying an audio signal having a channel, from among the plurality of channels, giving a sense of elevation to a filter to generate a plurality of virtual audio signals to be respectively output to a plurality of speakers, applying a combination gain value and a delay value to the plurality of virtual audio signals so that the plurality of virtual audio signals respectively output through the plurality of speakers form a sound field having a plane wave, and respectively outputting the plurality of virtual audio signals, to which the combination gain value and the delay value are applied, through the plurality of speakers. The filter processes the audio signal to have a sense of elevation.

摘要： Most computer operating systems are able to automatically configure the coupled computer peripheral audio device for use with the computer operating system without the need for installation of a specific driver. However, when these computer peripheral audio devices are detected by the computing system, a generic audio device control configuration is often assigned to them and whatever customised settings previously configured by the user will be lost and replaced with a new set of unfamiliar setting. This poses much inconvenience and hassle to gamers when they use a different computing system or machine. Described according to an embodiment of the invention is a headset device and a device profile management method, operating on a computing cloud, comprising steps for receiving client data provided by a computing system detecting coupling of an audio device thereto and for retrieving configuration data corresponding to the client data for use in configuring the audio device by the computing system.

摘要： A multi-channel audio rendering system comprises an audio renderer (113) which generates audio signals for a plurality of audio channels. A plurality of interchangeable speaker units (101-109) comprises a battery (205) and an audio transducer (207) for rendering an audio signal. A charging unit (115) is associated with a specific audio channel and comprises a charging source which can charge the battery of an attached speaker unit (101-109). A linking circuit (305) can link the speaker unit (101-109) to the first audio channel when it is attached to the charging unit (115). The system can permanently associate specific channels with charging units (or passive speaker bases that cannot charge) and interchangeable speaker units (101-109) can adapt depending on their attachment. The approach may allow a charging of a (possibly wireless) speaker unit (101-109) to be achieved simply by swapping this speaker unit (101-109) with one attached to a charging unit (115).
