A low-delay audio codec using the ADPCM structure (ADPCM = adaptive differential pulse code modulation) in subbands is presented. With the use of 8 subbands a coarse spectral shaping of the coding noise is obtained and the signal delay is approximately 3 ms. Codec stands for en co de/ dec ode. 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.
