"""Compatibility re-export: the Realtime audio codec moved out of the duplex engine.

Decoding PCM / G.711 / WAV, resampling and re-encoding are wire-format work with
no duplex session in them, so the implementation now lives in
``vllm_omni.protocol.realtime.audio`` where a non-duplex Realtime surface can
use it too. Duplex code reaches it through ``vllm_omni.protocol.duplex``, the
one door the engine uses --- which is also where a duplex-specific conversion
would be introduced. Import from there in new code.
