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.
|
|
|
|
Test: manual, with various headphones, receivers, and speakers
|
