Classification: CPC H | IPC H

Claim 15:
16. An apparatus for audio processing, the apparatus comprising:
one or more loudspeakers;
a microphone;
a processor; and
a memory,
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;
wherein the processor is configured to control the one or more loudspeakers to output, in a second room different from the first room, a plurality of audio signals using the first plurality of loudspeaker tunings;
wherein the processor is configured to control the microphone to receive, in the second room, the plurality of audio signals;
wherein the processor is configured to compute 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;
wherein the processor is configured to compute 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;
wherein the processor is configured to combine the first plurality of loudspeaker tunings and the second plurality of loudspeaker tunings to generate a third plurality of loudspeaker tunings; and
wherein the processor is configured to control the one or more loudspeakers to output an audio signal using the third plurality of loudspeaker tunings.
