A Bluetooth DAC (Digital-to-Analog Converter) is a device that converts digital audio signals transmitted via Bluetooth into analog signals that can be played through speakers or headphones. This process allows for high-quality sound reproduction from various digital sources, such as smartphones, tablets, or computers, enhancing the listening experience. Bluetooth DACs are often used in conjunction with wireless headphones or speakers to improve audio quality. They can support various audio formats and often include features like aptX or LDAC for better sound fidelity. By using a Bluetooth DAC, users can enjoy clearer and more detailed audio without the limitations of standard Bluetooth audio.
