CSR has launched the BlueTunes ROM, the world’s first ROM-based Bluetooth solution for stereo headsets with an integrated Digital Signal Processor (DSP). It is designed to provide end-users with the ability to seamlessly switch between wireless music playback and voice calls. BlueTunes ROM supports both SBC and MP3 (license required) decoding for improved audio quality on music playback, together with a configurable 5 band EQ to improve the end-user experience. The low power design of BlueTunes ROM enables over 10hrs of music playback from a 180mAh battery.

In addition, BlueTunes ROM integrates FastStream, a low latency high-quality music and voice CODEC which significantly reduces the latency of the audio link to avoid “lip-sync” issues. This is useful when watching video images and listening to audio on a headset or speakers. Standard Bluetooth solutions have a latency of up to 200ms, which restricts their use in real-time applications such as gaming, video or mobile TV.

Anthony Murray, Senior Vice President of CSR’s Wireless Audio Strategic Business Unit said, “BlueTunes ROM provides manufacturers with the opportunity to design smaller, lighter, more cost effective and feature rich Bluetooth stereo headsets. With more manufacturers combining MP3 players with mobile phones, BlueTunes ROM allows users to switch easily between music and calls using wireless connectivity. We have incorporated our FastStream and CVC technologies to ensure that headset manufacturers are able to provide their customers best in class, market leading audio quality.”
