Dual Audio enables simultaneous capture, processing, and output of two independent audio streams within a single system or application. Typical use cases: bilingual media playback (simultaneous/alternate language tracks), live interpretation, assistive listening (separate channels for commentary vs. program audio), remote conferencing with distinct channel mixes, and redundancy/backup audio for broadcast. This proposal describes system architecture options, data flows, formats, UX patterns, performance and latency considerations, testing and rollout plan, and recommendations for implementation.
