ATLAS software automatically controls volume and extracts voice from background noise

Nokia has selected Wolfson Microelectronics' ATLAS DSP software for its Reaction Bluetooth Headset. Developed by Wolfson's Dynamic Hearing division, ATLAS uses the microphone signals in the headset to capture the user's voice from the surrounding noise. Anthony Shilton, GM of Wolfson Dynamic Hearing, said: "ATLAS is optimised to help deliver crystal-clear audio and reduced background noise for Bluetooth headsets." Nokia's Reaction Bluetooth headset is completely automatic and features three microphones and an automatic volume control to deliver clear audio and help block out background noise.
