But these two algorithms are lossy compression, which will affect the sound quality. So Sony invented LDAC, Qualcomm invented APT-X and Huawei invented HWA. These are proprietary coding and compression algorithms. Not all manufacturers support it. But because they are all industry leaders, they will build their own ecology. In addition, the self-developed codec is beneficial to intellectual property protection.
Introduction:
A2DP is a kind of Bluetooth in the market, and its full name is Advanced Audio Distribution Summary Bluetooth Audio Transmission Model Protocol. A2DP can use the chip in the earphone for data superposition to realize high definition of sound. The earphone with A2DP is a Bluetooth stereo earphone. The sound can reach 44. 1kHz, while ordinary headphones can only reach 8kHz.
If the mobile phone supports Bluetooth, you can use A2DP headphones as long as A2DP protocol is loaded. There are also consumers who see that the technical parameters refer to Bluetooth V1.0v1.1v1.2v2.0-these refer to the technical version of Bluetooth and the transmission speed through Bluetooth. Whether they support A2DP depends on whether Bluetooth product manufacturers use this technology.
