The Bluetooth Technology Alliance has worked with several industry players to develop a Bluetooth SIG specifically tailored to the needs of gaming applications.Gaming Audio Profile 1.0 (GAP 1.0)Technical standards are used to meet the needs of games that require faster sound output performance or shorter delays in live broadcasts.
This technical standard is a collaborative effort among industry players including Sony, Bose, Demant, Intel, Plantronics, Dolby Laboratories, OPPO, Qualcomm, Shanghai Tailing Microelectronics, Philips, the Fraunhofer Institute of Germany, NXP, Ericsson, and GN Hearing, which holds the Jabra brand.
It incorporates LE Audio's Auracast broadcast mode application function, and can use the UGG connection protocol to allow two-way audio transmission between the phone and the right earphone, one-way sound transmission to the left earphone only, or two-way audio transmission to both left and right earphones simultaneously. In addition, broadcast mode can also be used to transmit audio to both earphones through the gaming device.
This design breaks the previous situation where audio transmission is often restricted to call mode and limited bandwidth when using Bluetooth headsets for online game calls and live streaming applications. It allows users to transmit CD-quality audio at a frequency of 48kHz during the game, and only transmit in-game voice content at a frequency of 32kHz, thereby corresponding to clearer and faster sound transmission effects.
It is expected that under the Gaming Audio Profile 1.0 technical standard, future headphone products designed for gaming and live streaming applications will be able to be used directly via Bluetooth connection, eliminating the need for a dedicated transceiver to transmit in the 2.4GHz wireless band, thereby streamlining headphone product design.
