Abstract:
An audio production method, comprising:providing at least one track in a plurality of audio tracks, the one track comprising primary content pure voice (PCPV) audio, the plurality of audio tracks stored on a storage medium, and the plurality of audio tracks having a time-synchronization; generating a PCPV signal from the at least one track; compressing the PCPV signal using a digital compression format having a first compression ratio; providing at least one other track in the plurality of audio tracks, the at least one other track comprising secondary content remaining audio (SCRA) audio; generating an SCRA signal from the at least one other track; compressing the SCRA signal using a digital compression format having a second compression ratio; creating a voice-to-remaining-audio (VRA) auxiliary data channel, the VRA auxiliary data channel: identifying a VRA-capable digital master as VRA-capable, and identifying playback parameters of the PCPV and SCRA signals; digitally storing on the VRA-capable digital master: the PCPV signal, the SCRA signal, and the VRA auxiliary data channel; wherein the storing step maintains the time-synchronization.
