Subject: [PATCH] Increase maximum Bluetooth SBC codec bitrate for SBC HD
This commit increases maximum possible bitrate to 452 kbit/s for 44.1 kHz,
492 kbit/s for 48 kHz, which is optimal for both
EDR 2 mbit/s (4 audio frames, 11.7 ms, 6 wasted bytes) and
EDR 3 mbit/s (6 audio frames, 17.5 ms, 20 wasted bytes).
It does not increase bitpool value and won't introduce higher bitrates for
modes other than SBC Dual Channel.

Subject: [PATCH] Explicit SBC Dual Channel (SBC HD) support
Overwhelming majority of Bluetooth audio devices have SBC maximum bitpool value
limited to 53, which prevents bitrates higher than 328 kbit/s to be used with
the most common 44.1 kHz Joint Stereo, 8 subbands, 16 blocks profile. This
limitation could be circumvented on any existing device to achieve higher audio
quality, by using Dual Channel mode.
Dual Channel encodes channels separately, using the entire bitpool for each
channel. Forcing the device to use Dual Channel instead of Joint Stereo almost
doubles maximum possible bitrate for the same bitpool value.
A2DP specification v1.2, which was active from 2007 to 2015, requires all
decoders to work correctly with bitrates up to 512 kbps. Newer specification
does not have the limit at all. It is assumed that most modern headphones with
EDR support can handle any SBC profile with maximum bitpool value, regardless
of resulting bitrate.
This commit defines optimal Dual Channel bitrate profiles:
EDR 2mbit/s - 452 kbit/s for 44.1 kHz, 492 kbit/s for 48 kHz (bitpool 38,
4 audio frames, 10.7 ms, 6 wasted bytes per packet)
EDR 3mbit/s - 551.3 kbit/s for 44.1 kHz, 600 kbit/s for 48 kHz (bitpool 47,
5 audio frames, 13.4 ms, 4 wasted bytes per packet)
With 452 kbit/s, SBC outperforms aptX, with 551.3 kbit/s, on par or close to
aptX HD.
53 out of 57 tested headphones, receivers and automotive head units were able
to correctly receive and decode high bitrate Dual Channel audio.
SBC HD is disabled by default and could be activated in Bluetooth device menu,
per device.
