摘要： In some embodiments, a method for automatic detection of polarity of speakers, e.g., speakers installed in cinema environments. In some embodiments, the method determines relative polarities of a set of speakers (e.g., loudspeakers and/or drivers of a multi-driver loudspeaker) using a set of microphones, including by measuring impulse responses, including an impulse response for each speaker-microphone pair; clustering the speakers into a set of groups, each group including at least two of the speakers which are similar to each other in at least one respect; and for each group, determining and analyzing cross-correlations of pairs of impulse responses (e.g., pairs of processed versions of impulse responses) of speakers in the group to determine relative polarities of the speakers. Other aspects include systems configured (e.g., programmed) to perform any embodiment of the inventive method, and computer readable media (e.g., discs) which store code for implementing any embodiment of the inventive method.

摘要： An apparatus and method of rendering audio. A binaural signal is split on an amplitude weighting basis into a front binaural signal and a rear binaural signal, based on perceived position information of the audio. In this manner, the front-back differentiation of the binaural signal is improved.

摘要： In some embodiments, a method for embedding data (e.g., metadata for use during post-processing) in a stereo audio signal comprising frames. Each of the frames has a saturation value, and data are embedded in the stereo audio signal by modifying the signal to generate a modulated stereo audio signal comprising a sequence of modulated frames having modulated saturation values indicative of the embedded data. Typically, one data bit is embedded in each frame of an input stereo audio signal by modifying the frame to produce a modulated frame whose modulated saturation value matches a target value indicative of the data bit. In other embodiments, a method for extracting data from a stereo audio signal in which the data have been embedded in accordance with an embodiment of the inventive embedding method. Other aspects are systems (e.g., programmed processors) configured to perform any embodiment of the inventive method.
