Abstract
A method of enhancing audio sound. The method includes sensing an acoustic signal using a microphone in an electronic device. The acoustic signal is emitted in response to a primary sound signal and transmitted as a sound wave through a space. The method further includes receiving, using an antenna in the electronic device, a wireless signal encoded with the primary sound signal. An impulse response for the space is estimated based on the sensed acoustic signal and the primary sound signal encoded within the received wireless signal. A delay between the sensed acoustic signal and the primary sound signal encoded within the received wireless signal is calculated based on the estimated impulse response. The primary sound signal encoded within the received wireless signal is delayed using the calculated delay and reproduced to enhance the acoustic signal heard by a user of the electronic device.
