Nowadays, consumers' demand for mobile calls is increasing, which makes people's requirements for sound quality gradually increase, so ultra-wideband voice codecs come into being. By applying this technology to mobile devices, the quality of mobile calls can be significantly improved, allowing more consumers to enjoy high-quality voice calls on mobile terminals. However, when consumers use accessories that support the Bluetooth hands-free specification to make and receive voice calls, they cannot experience the same level of high-definition voice. The Bluetooth headset solution launched by Dalian Daquanding based on the Qualcomm QCC5144 chip can effectively solve the above problems and provide consumers with excellent voice call effects.

QCC5144 is a high-end chip designed for Bluetooth audio devices. It uses Qualcomm aptX Voice audio technology to provide high-fidelity voice call quality for Bluetooth wireless connection technology. Compared with the narrowband and wideband codecs used in the current Bluetooth hands-free specification, aptX Voice can provide users with a better call experience by improving the overall voice quality, thereby reducing listener fatigue, which is very important for those who need to maintain high-quality voice calls in noisy environments.

In addition, aptX Voice supports 32kHz sampling audio with a 16kHz smooth frequency response, making it easier to recognize speech, distinguish confusing sounds, and understand the semantics of callers with accents, thereby improving users' semantic understanding and achieving excellent speech understanding even in other sound quality-impaired environments.
