Abstract
The subject disclosure is directed towards calibrating sound pressure levels of speakers to determine desired attenuation data for use in later playback. A user may be guided to a calibration location to place a microphone, and each speaker is calibrated to output a desired sound pressure level in its current acoustic environment based upon the attenuation data learned during calibration. During playback, the attenuation data is used. Also described is testing the setup of the speakers, and dynamically adjusting the attenuation data in real time based upon tracking the listener's current location.
