How is high-quality sound from the microphone of the bluetooth headset on the phone achieved and why is it not available for the computer?

Question

Android

Hello, does anyone know why on android with bluetooth headphones there is a good sound from a microphone, but on a computer it is so bad? As I understand it, the bluetooth headset microphone on the computer only works on the hsp / hdp profile, but how is high-quality sound from the microphone achieved on android? At the same time, when talking through headphones on the phone, it is displayed in sony control - ldac, does it allow the microphone to work as well? Can you do the same on a computer?

If you look at voice recorders (audio recording programs on Android), then at the core and the rest around is just a beautiful interface and a wrapper into a service. I mean, there are no merits of applied developers in good sound under android. Hardware noise reduction and a cool base system class (codecs are also out of the box) Sound is the main task for a phone. The system guys got out. And under Windows, a maximum of bluetooth speakers got confused. If you look then there were several competing stacks for Windows. Try google bluesoilery. About 8-10 years ago, under XP, they had a separate paid product.
