The Bluetooth low-complexity, subband codec (SBC) is described in the
specification of the Advanced Audio Distribution Profile (A2DP) in appendix B.
SBC is an audio coding system specially designed for Bluetooth audio and
video applications to obtain high quality audio at medium bit rates with low
computational complexity. It uses 4 or 8 subbands, an adaptive bit allocation
algorithm, and simple adaptive block PCM quantizers.
SPIRIT SBC codec is implemented according to Bluetooth Advanced Audio
Distribution Profile (A2DP) specification - as the only mandatory codec for
wireless audio.
