摘要： A system for improving intelligibility or loudness of an audio program includes an encoder that receives signals of the audio program including at least one of left/front and right/front or left and right signals that include some anchor components of the audio program and to downmix the received signals to obtain left downmix and right downmix signals. The system includes a decoder that upmixes the left downmix and right downmix signals to obtain a center upmix signal that includes a majority of the anchor components including at least some anchor components that were included in the left/front and right/front signals or the left and right signals. The system also includes a system output that provides the center upmix signal to process at least one of the signals of the audio program based on the center upmix signal to improve intelligibility or loudness of the audio program.

摘要： A system for monitoring detectability of a watermark message produced by a watermarking encoder includes an input that receives a watermarked signal having spectral channels in which the watermark message is embedded. The system also includes channel separators each associated with a respective spectral channel of the watermarked signal and configured to separate the watermarked signal into spectral channels. The system also includes bin separators configured to separate the spectral channels into frequency bins. The system also includes a detector configured to detect a frequency bin corresponding to a symbol that appears in a plurality of the spectral channels. The system also includes a detectability estimator configured to establish a measure of the detectability of the watermark message embedded in the watermarked signal based at least in part on the frequency bin corresponding to the symbol that appears in the plurality of the spectral channels.

摘要： Providing feedback regarding potential detectability by a decoder of a watermark message produced by a watermarking encoder includes receiving a watermark detectability indication that does not directly correspond to detectability of the watermark message by the decoder but is only a proxy for detectability of the watermark message by the decoder, transforming the watermark detectability indication into an enhancement indication corresponding to a prescribed enhancement to a watermark signal in which the watermark message is embedded based on the watermark detectability indication, and transmitting the enhancement indication to enhance the watermark signal thereby enhancing detectability of the watermark message.
