Synopsys ARC® Audio LC3 Codec (Bluetooth LE Audio)
The LC3 codec algorithm for DesignWare® ARC® processors was designed as a low complexity communications codec within the Bluetooth LE Audio specification, to deliver voice and audio streaming. The LC3 codec supports six sample rates within the range of 8kHz to 48kHz and multiple channels are supported with 16 to 320k bits per second per channel.
The LC3 codec for ARC processors has been certified per the approach mandated by the Bluetooth SIG.
The LC3 codec for ARC processors has been certified per the approach mandated by the Bluetooth SIG.
