SBC Codec

The so-called SBC codec is a codec for transferring audio data. The acronym SBC stands for "Low Complexity Subband Coding". The SBC codec is primarily used for the wireless Bluetooth standard and is part of the Bluetooth profile A2DP. A2DP is required to support the SBC codec. Unlike other codecs, SBC is public domain and can therefore be freely implemented by the various equipment manufacturers. Similar to the MP3 compression method, SBC codec is lossy. Audio signals compressed with this codec cannot be restored to their full original form. The benefits of SBC is the low demand for computing power in the compressing and unpacking devices and supporting bit rates of up to 345 kilobit per second.
