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.
