1. A method, performed by a device, comprising
obtaining a plurality of microphone signals of a microphone array;
detecting, based on the plurality of microphone signals, whether the device moves from a first environment to a second environment;
in response to detecting the move to the second environment, determining a reverberation time of the second environment; and
modifying a playback audio signal based on the reverberation time.
