Abstract
In certain aspects, a leakage compensation method and system for a headphone are disclosed. An audio reference signal is obtained responsive to an audio signal to be played by a speaker of the headphone. An audio feedback signal is obtained based on a microphone signal acquired by a microphone of the headphone responsive to the audio signal being played by the speaker. One or more compensation parameters of a compensation filter are determined based on the audio reference signal and the audio feedback signal. The compensation filter is configured using the one or more compensation parameters. A music signal is processed using the compensation filter to generate a leakage-compensated music signal to be played by the speaker.
