Abstract: 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.

Abstract: 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.
Abstract translation: 一种用于对音频信号进行水印的机器或机器组的方法包括接收包括多个符号的音频信号和水印信号，以及在音频信号的多个频谱信道中插入多个符号中的至少一些，每个频谱信道对应于 不同的频率范围。 设计的优化包括通过考虑感知时频屏蔽，水印消息的模式检测，最坏情况节目内容（例如语音和语音节目）的统计来最小化感知水印信道的人类听觉系统。

Abstract: 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.

Abstract: A method for a machine or group of machines to watermark speech audio transmissions includes receiving a speech audio signal, receiving a watermark signal including a message of multiple bits, each bit having one of two values, each value represented by one of two symbols, each of the symbols corresponding to a respective audio segment, and at a time t1, transmitting a first transmission including at least some of the multiple bits in multiple spectral channels of the speech audio signal, each spectral channel corresponding to a different frequency range, wherein a first one of the multiple spectral channels carries a first bit from the multiple bits while at the same time a second one of the multiple spectral channels carries a second bit from the multiple bits different from the first bit.
