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 method for a machine or group of machines to carry watermark data in an encoded audio data frame of an audio signal includes receiving the encoded audio data frame having encoded therein a portion of the audio signal. The encoded audio data frame includes a plurality of data blocks, wherein the plurality of data blocks includes, a synchronization information block, at least one encoded data block, and an error check block. The method further includes receiving modified watermark data as modified based on a masking threshold analysis of the audio signal and transforming the encoded audio data frame into a modified encoded audio data frame.
