SBC. SBC, also called “Low Complexity Subband Codec”, is part of the Bluetooth profile “A2DP” (see above). Its (lossy) compression makes comparatively low demands on the hardware and therefore requires little computing power. The use of the code SBC is license-free, so it is often used. Speex wideband mode (sub-band CELP) For wideband, the Speex approach uses a q uadrature m irror f ilter (QMF) to split the band in two. The 16 kHz signal is thus divided into two 8 kHz signals, one representing the low band (0-4 kHz), the other the high band (4-8 kHz). The low band is encoded with the narrowband mode described in section 8 in ...Improving Audio Codecs by Noise Substitution.

Because raw audio data is too large to transmit and stream in real-time, audio must be compressed (encoded) using a codec before it's streamed over Bluetooth A2DP (Advanced Audio Distribution Profile). Once the encoded audio is recevied by the output device, it is decoded before it can be played.
