Bluetooth Stereo Headphones?
Posted by Janak Parekh in "HARDWARE" @ 12:28 PM
One of the big problems of Bluetooth 1.1 for audio listening is that it only supports up to about 720kbps, or about 90kBps. This is not enough to transmit uncompressed stereo 44KHz 16-bit PCM audio, which requires 162kBps of bandwidth. However, this company is developing a reference platform that will natively support compressed audio in the headphone design itself, and will do the decoding there. It seems that this is built on a special profile, called "Advanced Audio Distribution Profile (A2DP)". Let's hope this technology hits the PDA markets... or that Bluetooth 2 hits soon -- wireless stereo listening is the way of the future.
