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.
