1. A method of audio processing, the method comprising:
providing an apparatus having one or more loudspeakers, a memory and a microphone, wherein the memory is configured to store a first plurality of loudspeaker tunings, wherein the first plurality of loudspeaker tunings corresponds to a first room impulse response of the one or more loudspeakers measured in a first room;
outputting, in a second room different from the first room, a plurality of audio signals by the one or more loudspeakers of the apparatus using the first plurality of loudspeaker tunings;
receiving, in the second room, the plurality of audio signals by the microphone of the apparatus;
computing, by the apparatus, a second room impulse response based on the plurality of audio signals having been received by the microphone, wherein the second room impulse response includes an early response and a late response;
computing, by the apparatus, a second plurality of loudspeaker tunings based on the second room impulse response, wherein the second plurality of loudspeaker tunings is based on the late response and excludes the early response;
combining the first plurality of loudspeaker tunings and the second plurality of loudspeaker tunings to generate a third plurality of loudspeaker tunings; and
outputting an audio signal by the one or more loudspeakers of the apparatus using the third plurality of loudspeaker tunings.
