CSR has announced a new single-chip solution to enhance the performance of Bluetooth-enabled portable devices: music phones to MP3 players. MusiCore1 packs advanced audio distribution profile (A2DP) and Bluetooth wireless personal area network (WPAN) functionality into a single semiconductor device that is smaller than most dedicated Bluetooth chips. CSR claims that without compromising on cost or size, MusiCore1 allows mobile handset designers to differentiate their products through advanced audio features:
Long music playback time
* 3D Stereo Enhancement Algorithms and 80 hours using Bluetooth headphones (100 hours via wired headphones)
* Stereo enhancement algorithms to make music sound even better
* Wavetable MIDI Synthesizer
Fantastic voice quality
* Dual-mic noise cancellation for transmitted voice (up to 32 dB reduction)
* Automatic volume control and audibility enhancement for received voice
* Full duplex, loud speaker-phone in handsfree mode
State of the art Bluetooth
* Full support for Bluetooth v2.1
* Built-in SBC transcoding for stereo streaming
* Low latency mode that eliminates ‘lip synchronisation’ issues when watching videos on a handset and using wireless headphone
