PulseAudio 15 Lands mSBC Codec Support To Enable Bluetooth Wideband Speech
The latest work to land on Monday for the PulseAudio sound server was mSBC codec support for its Bluetooth native headset backend. This mSBC codec support in turn allows for wideband speech to be supported for capable Bluetooth headsets interfacing with the Linux desktop by way of PulseAudio.
This mSBC codec support will be used by default for headsets claiming to support it but can be optionally disabled by the user.
After the initial merge request was opened a month ago, this Bluetooth mSBC support was improved upon and has been tested with the likes of Apple Airpods Pro and various other Bluetooth devices from the likes of Bose, Sony, and LG. This work should yield better sound quality for modern Bluetooth headsets with PulseAudio.
See the merge request for more details if interested. This will be part of the upcoming PulseAudio 15.0 release.
