@AhsanJamal10 A2DP stands for Advanced Audio Distribution Profile. This is the Bluetooth Stereo profile which defines how high quality stereo audio can be streamed from one device to another over a Bluetooth connection - for example, music streamed from a mobile phone to wireless headphones.
It isn't something that can be converted, it's a passive feature and If your smartphone, tablet, or computer has Bluetooth, but your stereo or other speaker system doesn't, a good Bluetooth audio receiver lets you stream music wirelessly to your speakers with little loss in sound quality
