But, many contents are encoded at 48 kHz, including many video contents. Windows inbox A2DP driver supports only 44.1 kHz sampling frequency for SBC CODEC. If you want to eliminate sound quality loss by the downsampling Please see the FAQ for the step-by-step instructions. The other knob is using Dual Channel mode instead of using Joint Stereo, which is used by the Windows inbox driver. One is simply to increase the bitpool parameter. If your headphones are working fine with the Windows inbox driver, you may want to increase the bitrate and enjoy the better sound quality. If you want to increase the bitrate of the audio stream This will slightly reduce audio quality but significantly reduces the annoying noises. If that is the case, reducing the bitrate (the amount of the data transmitted) and creating more time to re-transmit may be able to eliminate packet loss. This is one of the reasons why you hear stuttering/choppy noise. So, if the Bluetooth radio's signal quality is poor (due to the lack of adequate antenna, interference with other radio signals, etc.) and causes a lot of re-transmission, it will start dropping streaming data packets (or the packet is not delivered on time). If you are suffering from stuttering/choppy noiseĪ2DP transmits data with error detection and re-transmission.

Please see the FAQ on how to get stable, high-quality streaming. If your headphones support the aptX HD (many Qualcomm chip-based headphones do) or LDAC (most mid/high-end Sony headphones do), and your Bluetooth radio condition is reasonably good, there is no reason not to use it. Who is this software for? If your headphones support aptX HD or LDACĪptX HD and LDAC can provide higher-quality audio than other CODECs such as SBC, AAC, and aptX.

Alternative A2DP Driver is a device driver that replaces Windows 10/11 inbox Bluetooth A2DP driver and allows you to fine-tune CODED parameters.
