Abstract
A method for delay estimation of audio signals using an impulse response signal is provided. The method includes determining an energy envelope for the impulse response signal based on a moving average function of the impulse response signal. The method further includes determining an estimated delay of the impulse response signal based on at least one characteristic of the determined energy envelope. At least one audio signal phase is adjusted for at least one audio driver based on the estimated delay.
