1. A system comprising:
- an audio output device that outputs audio signals to a plurality of speakers;
a sound pressure level meter coupled to a microphone, the microphone configured to detect audio from the plurality of speakers, the sound pressure level meter obtaining sound pressure level meter readings from the detected audio; and
a calibration mechanism configured to;
recognize one or more themes in the detected audio from the plurality of speakers,obtain attenuation settings that are specific to the one or more recognized themes in the detected audio, andperform at least one calibration operation, based upon the readings, that attenuates the audio signals provided to the plurality of speakers according to the attenuation settings specific to the one or more recognized themes in the detected audio,wherein calibration settings for the one or more themes correspond to one or more audio modes, the one or more audio modes having varying levels of loudness.

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.

12. A method performed at least in part on at least one processor, comprising:
-
analyzing streaming video for metadata related to audio associated with the video; identifying speaker calibration settings from the metadata of the audio associated with the video; dynamically adjusting speaker output settings based on the identified speaker calibration settings from the metadata of the audio associated with the video; directing a plurality of speakers to play the audio according to the adjusted speaker output settings; and monitoring sound pressure levels of the plurality of speakers to determine whether the plurality of speakers are correctly adjusted based on the identified speaker calibration settings; wherein the speaker calibration settings for one or more themes associated with the audio correspond to one or more audio modes, the one or more audio modes having varying levels of loudness. - View Dependent Claims (13, 14, 15, 16)

17. One or more machine-readable storage devices embodied with executable instructions for calibrating audio output, comprising:
-
recognizing one or more themes in audio detected from a plurality of speakers, obtaining attenuation settings that are specific to the recognized one or more themes in the detected audio, and performing at least one calibration operation, based upon sound pressure level meter readings from the detected audio by a sound pressure level meter, that attenuates audio signals provided to the plurality of speakers according to the attenuation settings specific to the recognized one or more themes in the detected audio, wherein calibration settings for the one or more themes correspond to one or more audio modes, the one or more audio modes having varying levels of loudness. - View Dependent Claims (18, 19, 20)
