Original Abstract Submitted

some methods may involve receiving a first content stream that includes first audio signals, rendering the first audio signals to produce first audio playback signals, generating first calibration signals, generating first modified audio playback signals by inserting the first calibration signals into the first audio playback signals, and causing a loudspeaker system to play back the first modified audio playback signals, to generate first audio device playback sound. the method(s) may involve receiving microphone signals corresponding to at least the first audio device playback sound and to second through nth audio device playback sound corresponding to second through nth modified audio playback signals (including second through nth calibration signals) played back by second through nth audio devices, extracting second through nth calibration signals from the microphone signals and estimating at least one acoustic scene metric based, at least partly, on the second through nth calibration signals.
