TL;DR: In this paper, a system for operator interaction is provided using a stored program digital data processor and an audio message sub-system to process digital information and to provide audio messages for operator interactions.
Abstract: A system for operator interaction is provided using a stored program digital data processor and an audio message sub-system to process digital information and to provide audio messages for operator interaction. The system utilizes a digital data processor to execute program routines to process digital information and to communicate with an operator using audio messages. Digital message information is stored in a digital memory. The digital message information is accessed in response to operator generated signals to provide audio messages, in contrast to the prior art visual messages using displays and printers.

TL;DR: In this paper, an input multi-channel representation is converted into a different output multichannel representation of a spatial audio signal, in which an intermediate representation of the audio signal is derived, the intermediate representation having direction parameters indicating a direction of origin of a portion of the signal.
Abstract: An input multi-channel representation is converted into a different output multi-channel representation of a spatial audio signal, in that an intermediate representation of the spatial audio signal is derived, the intermediate representation having direction parameters indicating a direction of origin of a portion of the spatial audio signal; and in that the output multi-channel representation of the spatial audio signal is generated using the intermediate representation of the spatial audio signal.

TL;DR: In this paper, a method of operating an audio system in an automobile includes identifying a user of the audio system and an audio recording playing on the audio systems is identified and stored in memory in association with the identified user and the identified audio recording.
Abstract: A method of operating an audio system in an automobile includes identifying a user of the audio system. An audio recording playing on the audio system is identified. An audio setting entered into the audio system by the identified user while the audio recording is being played by the audio system is sensed. The sensed audio setting is stored in memory in association with the identified user and the identified audio recording. The audio recording is retrieved from memory with the sensed audio setting being embedded in the retrieved audio recording as a watermark signal. The retrieved audio recording is played on the audio system with the embedded sensed audio setting being automatically implemented by the audio system during the playing.
