The DesignWare® ARC® Audio Bluetooth LC SBC Encoder and Decoder for the DesignWare ARC AS211SFX and AS221BD audio processors implements Low Complexity Sub-band Coding (LC SBC) as defined by Bluetooth Advanced Audio Distribution Profile (A2DP).
The Bluetooth LC SBC Encoder and Decoder uses four or eight sub-bands, adaptive bit allocation algorithms and adaptive block Pulse Code Modulation (PCM) quantizers. Applications include wireless audio streaming for a wide range of devices such as headphones, wireless speakers, navigation devices and car kits for mobile phones. The DesignWare ARC Bluetooth LC SBC Encoder and Decoder is optimized for low processor load and small memory footprint, with additional optimizations for full-duplex mode.
