Techniques for accommodating primary content (pure voice) audio and secondary content remaining audio capability in the digital audio production process
First Claim
1. A non-transitory computer-readable storage medium whose contents cause an audio and/or video device to perform operations for decoding a voice-to-remaining-audio-capable (VRA-capable) audio program stored on the storage medium, the operations comprising:
- identifying VRA data stored in the storage medium that assigns individual primary content pure voice (PCPV/PCA) audio tracks to first individual spatial channels and also assigns individual contextual audio tracks to second individual spatial channels, wherein the first and second individual spatial channels comprise non-VRA based audio channels; and
decoding the audio program based at least in part on the assignments contained in the VRA data.

Abstract
The invention enables the inclusion of voice and remaining audio information at different parts of the audio production process. In particular, the invention embodies special techniques for VRA-capable digital mastering, accommodation of PCPV/PCA and/or SCRA signals in audio CODECs, VRA-capable encoders and decoders, and VRA in DVD and other digital audio file formats. The invention facilitates an end-listener'"'"'s voice-to-remaining audio (VRA) adjustment upon the playback of digital audio media formats by focusing on new configurations of multiple parts of the entire digital audio system, thereby enabling a new technique intended to benefit audio end-users (end-listeners) who wish to control the ratio of the primary vocal/dialog content of an audio program relative to the remaining portion of the audio content in that program. The invention facilitates storage of VRA audio programs on optical storage media, authoring systems for VRA-capable DVDs, playback hardware integrated into VRA-capable optical disc apparatus, and VRA playback hardware for use with non-VRA capable optical disc playback apparatus.

11. A method for storing a voice-to-remaining-audio-capable (VRA-capable) audio program on a computer-readable storage medium, the method comprising:
-
receiving the VRA-capable audio program; creating VRA data from the VRA-capable audio program that assigns individual primary content pure voice (PCPV/PCA) audio tracks to first individual spatial channels and also assigns individual contextual audio tracks to second individual spatial channels, wherein the first and second individual spatial channels are non-VRA based audio channels; storing the VRA-capable audio program on the storage medium; and storing the VRA data on the storage medium. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An apparatus for producing voice-to-remaining-audio-capable (VRA-capable) audio, comprising:
-
one or more individual signal paths corresponding to non-VRA based audio channels; and a post processor coupled to the one or more individual signal paths and configured to produce a first signal corresponding to at least one primary content pure voice (PCPV/PCA) audio track and a second signal corresponding to at least one contextual audio track, the first and second signals being based on audio information associated with the non-VRA based audio channels. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
