摘要： A method to watermark an audio signal may include receiving watermark data payload information, converting the watermark data payload information into a watermark audio signal including one or more watermark messages corresponding to the watermark data payload information, and inserting the one or more watermark messages into multiple spectral channels of the audio signal, wherein each of the multiple spectral channels occupies a different frequency range, wherein bandwidth of a first spectral channel located in a first frequency region is smaller than bandwidth of a second spectral channel located in a second frequency region, and wherein bandwidth of a spectral channel, from the multiple spectral channels, is equal to a number divided by the time duration of a respective symbol, from the multiple symbols, in the spectral channel, wherein the number is in the range of 0.7 to 2.5.

摘要： Determining effect of changes in parameters may include, during a time interval, rotating from setting a first parameter to a first value for a first time period, to setting the first parameter to a second value for a second time period such that the time interval includes multiple first time periods with the first parameter set to the first value sequenced with multiple second time periods with the first parameter set to the second value; obtaining, for the time interval, a first set of ratings corresponding to the first time periods and a second set of ratings corresponding to the second time periods; averaging, for the time interval, the first set of ratings to a first average rating and the second set of ratings to a second average rating; and correlating the first average rating to the first value and the second average rating to the second value.

摘要： A method to watermark an audio signal may include receiving watermark data payload information, converting the watermark data payload information into a watermark audio signal including one or more watermark messages corresponding to the watermark data payload information, and inserting the one or more watermark messages into multiple spectral channels of the audio signal, wherein each of the multiple spectral channels occupies a different frequency range, wherein, once an audio segment has been inserted into a spectral channel of the audio signal, amplitude of the audio segment is held constant for the time duration of the audio segment such that a first portion of the audio segment is masked by the audio signal and a second portion of the audio segment is not masked by the audio signal.

摘要： A method for a machine or group of machines to watermark an audio signal includes receiving an audio signal and a watermark signal including multiple symbols, and inserting at least some of the multiple symbols in multiple spectral channels of the audio signal, each spectral channel corresponding to a different frequency range. Optimization of the design incorporates minimizing the human auditory system perceiving the watermark channels by taking into account perceptual time-frequency masking, pattern detection of watermarking messages, the statistics of worst case program content such as speech, and speech-like programs.

摘要： Distributed audio mixing may include transmitting a set of parameters from a local location to one or more remote locations at least multiple miles away from the local location for, at each of the one or more remote locations, one or more remote audio sources to be processed according to the parameters to produce respective one or more remote audio mixes; processing one or more local audio sources according to the parameters to produce a local audio mix; receiving the one or more remote audio mixes; and locally summing the one or more remote audio mixes to the local audio mix to obtain a final audio mix.
