2 Mbit/s is the physical bit rate using LE 2M. After accounting for protocol overhead, the max data rate is about 1.4 Mbps. https://www.novelbits.io/bluetooth-

  Coincidentally (or not?) That's the bitrate of uncompressed CDDA. I suspect the real-word data rate is lower though. In any event 300kbps is more than sufficient for transparent compression of audio and, if the source is lossless, then you shouldn't have recompression artifacts. Doing so in real-time does have costs (low latency compression uses both more CPU time and ends up with higher bitrates than when you allow more latency)
