SBC. Sub-band codec is the basic codec Bluetooth audio devices have as it is compulsory for every device with the A2DP standard It is ubiquitous so there is no issue of incompatibility between devices and in the case of codec mismatch SBC is the default codec that will be reverted to. SBC has a bad reputation among the Bluetooth audio codecs for its high lossy compression algorithm and hence, overall lower audio quality. But in fact, SBC is a pretty flexible codec. It is able to support up to the 48 kHz sampling rate at 16-bit bit depth. It is also able to transmit data at rates as high as 345kbps.Explore the advantages of leveraging the Modified SBC Codec (mSBC) for Bluetooth devices.
