mSBC is a low complexity constant bitrate codec targeting speech applications. The modified subband codec is defined in Appendix A of the Hands Free Profile (HFP) specification. The original SBC specification is defined as part of the A2DP profile.

TI has taken the open source version of the SBC Codec provided as a part of BlueZ and modified it to support mSBC only, thus reducing the footprint and optimizing it for SimpleLink wireless micro controllers.

mSBC uses the following settings:

Parameter	Value
Channel mode	Mono
Sampling rate	16 kHz
Allocation method	Loudness
Subbands	8
Blocklength	15
Bitpool	26
Bit depth	16 bit

See the mSBC API for information about usage.
