Bluetooth sbc parameters

From http://soundexpert.org/news/-/blogs/bluetooth-audio-quality-a2dp , and https://android.stackexchange.com/questions/26410/how-do-i-determine-which-a2dp-codecs-my-phone-supports-is-currently-using , I can see that when I listen to bluetooth audio from my phone to my car, I am getting sbc with these parameters: Middle Quality Joint Stereo Samp Freq 44.1 kHz Bitpool value 35 Resulting Frame length 83 bytes Resulting bit rate 229 kb/s Block length 16 Allocation method = Loudness Subbands 8 Can someone share an equation of how these parameters relate to each other? Does any sbc at 44.1 KHz and bitrate 229 kb/s have to have bitpool = 35 and frame length 83 bytes?
