Abstract

This document specifies the Adaptive Layered Voice Container (ALVC), a codec-agnostic framing and metadata container that enables progressive voice delivery in constrained and lossy networks. ALVC defines a Base layer that is intelligible on its own at sub-kilobit rates, and optional Enhancement layers that improve quality when additional capacity is available. The container supports store-and- forward operation, progressive enhancement, unequal error protection signaling, and receiver behavior for seamless splice-and-improve playback. ALVC does not define a new speech coding algorithm; it multiplexes existing voice coders within a layered container.
