CSR has released a new product, BC6145. This is a state-of-the-art Bluetooth audio platform for single-microphone mono headsets, amplifiers, car kits and other mass-market wireless audio accessories. The BC6145 is the first ROM-based mono device to support a range of consumer-grade features including HD voice (“HD Voiceâ€) call quality, A2DP music streaming and advanced definition enhancement technology. The BC6145 also supports the superior performance of two-way noise reduction, as well as ultra-low-power wind noise suppression (WNR) technology, which significantly enhances the user experience of low-cost Bluetooth mono headsets. The BC6145 will be available soon, and this product further demonstrates CSR's technological leadership and leadership in the popular Bluetooth mono headset market. Mainstream manufacturers of mobile phones and Bluetooth accessories have also incorporated the audio platform into the next generation of headset design.

Improve voice quality
The BC6145 has greatly improved the call quality of wireless accessories and has become an important part of the continuous introduction of high-definition voice by network operators. After deploying high-definition voice services to selected major carriers (including France Telecom, 3UK and Orange), the BC6145 provides manufacturers with an opportunity to promote low-cost mono headsets that support the mSBC codec and bring The best user experience.
Integrating music into mono headphones With the popularity of media players and mobile phones that support A2DP music playback, the BC6145 will bring a lot of users the advantage of playing A2DP music with high quality audio. The outstanding features of this mono headset will help users enjoy mono music through earbuds or amplifiers. Although A2DP music streaming is achieved through low-cost mono headphones, it still provides OEM manufacturers with value-added features.
Improve speech intelligibility
The BC6145 features enhanced speech intelligibility technology. In this way, the headset user can receive voice content better in a noisy background environment. In addition to reducing the fatigue of the listener in longer conversations, the BC6145 can also improve the user's ability to "use one heart and two", such as talking while driving.
Thanks to the two-way noise reduction function, the headset equipped with the BC6145 achieves the noise reduction capability of the incoming call audio on the receiver side, thereby improving the user experience. The normal transmit path noise reduction function provided by other chip products can only be applied to the calling party.
The Wind Noise Reduction (WNR) algorithm features low power consumption and high performance, making it easy for headset users with the BC6145 to communicate clearly in high winds. The caller no longer has to "hide to the door" to answer the call. In addition, because wind noise suppression is only activated when wind noise is detected, OEMs do not have to worry about excessive power consumption when deploying this feature, especially in a non-active "listening" state.
The BC6145's high-definition sound quality is achieved through CSR's sixth-generation CVC speech enhancement software, which provides a range of algorithms for advanced audio functions such as packet loss and error concealment, ensuring harsh RF environments. Audio quality.
Extending consumer talk time thanks to the talk time extension feature, even in low battery conditions, the BC6145 can help headset users get an extra call duration of about an hour from the headset.
Anthony Murray, senior vice president of audio and consumer business at CSR, commented: "CSR's expertise in wireless audio platform technology has enabled today's feature-rich and low-cost ROM solutions. This is the first time that high-definition voice is implemented on Bluetooth devices. And new features like premium music, and the product is aimed at headphones, amplifiers and car kits that meet the mass market consumption level. In the process, BC6145 has set a new value for these sub-platforms, and has been widely upgraded. Consumer experience."
In addition to low-cost mono headsets, the BC6145 is also suitable for mass-market car kits and amplifiers. In the harsh noise environment of the car, the BC6145 greatly reduces speaker distortion and enhances echo cancellation.
As a CSR company's highly successful upgrade to the BC6140, the BC6145 is available in a pin-compatible QFN package, so many traditional BC6140-based headsets and amplifiers can be quickly upgraded to the BC6145 for enhanced functionality.
BC6145 is now in production in batches.
