A2DP
A2DP, now a days all higher end and most of the middle range mobiles are equiped with this techonlogy. many of us know what it does, but very few of us knows how it works. A2DP stands for Advanced Audio Distribution Profile. I know i am not writting anything new or some magic. But i am a big fan of this technology, it has given me big relife from this wired world of music.
what is A2DP?
The Advanced Audio Distribution Profile is a Bluetooth profile that allows for the wireless transmission of stereo audio from an A2DP source (typically a phone or computer) to an A2DP receiver (a set of Bluetooth headphones or stereo system). Such devices typically also support the AVRCP profile as well in order to allow for track selection and such. A common misconception is that A2DP support is available on all Bluetooth 2.0 devices, which is not the case, and that A2DP is only available on Bluetooth 2.0 devices, which is also not true. A2DP support can exist in older versions of Bluetooth, it just was not commonly supported.
