Abstract: A processor is configured to receive a plurality of sounds signals from a respective plurality of microphones. One or more localization algorithms is applied to the received plurality of sound signals to determine a plurality of source directions. A plurality of tracking directions is determined based on current values for the determined plurality of source directions and previous values for the determined plurality of source directions. An onset detection algorithm is applied to the received plurality of sound signals, and in response to detecting an onset, the processor is configured to determine an onset direction that represents the direction from the microphones to the source of the detected onset. A score is attributed to each of the determined plurality of tracking directions based on any determined onset directions and the one of the determined plurality of tracking directions that has the highest score is provided as a direction-output-signal.

Abstract: A wireless communication device is disclosed. The wireless communication device includes a processor, a memory, a transceiver configured to receive an audio signal, a codec to decode the audio signal, a dynamic range controller and a phoneme processor. The phoneme processor is configured to extract acoustic cues from each frame of the decoded audio signal and to identify a phoneme class in the each frame. The dynamic range controller is configured to apply dynamic range compression on the each frame based on the identified phoneme class.
