Abstract: A system for automatic control of audio processing based on at least one of playout automation information and broadcast traffic information includes a receiver configured to receive an electronic signal including scheduling data representing at least one of playout automation information and broadcast traffic information including at least timing and content type information of content, and a content logic configured to determine audio parameters for the processing of audio associated with the content based on the scheduling data.

Abstract: Improving loudness consistency of an audio stream may include delaying an encoded audio stream and adjusting the delayed encoded audio stream based at least in part on the loudness of the audio stream before a transition and the loudness of the audio stream after the transition. Improving loudness consistency of an audio stream may further include determining the loudness of the audio stream before the transition, detecting the transition, storing the loudness of the audio stream before the transition, and determining the loudness of the audio stream after the transition.

Abstract: A system for inserting auxiliary data into an audio channel that carries an audio signal includes a modulator configured to convert an auxiliary data signal into a modulated auxiliary data signal that has a passband within the audio channel's passband. The system for inserting auxiliary data into an audio channel that carries an audio signal further includes summing means configured to combine the modulated auxiliary data signal and the audio signal into a combination signal to be carried in the audio channel.

Abstract: A method of adding additional data to encoded bit streams may include receiving a signal containing an encoded data frame, where the encoded data frame includes a plurality of data blocks. The method may further include transforming the encoded data frame into a modified encoded data frame by inserting at least one additional data block between a synchronization information block and an error check block, where the at least one additional data block includes the additional data, and modifying data in at least one of the synchronization information block and the error check block to account for the inserting of the at least one additional data block.
