Technical Summary

  This document defines a mechanism by which packets of Real-Time
  Transport Protocol (RTP) audio streams can indicate, in an RTP header
  extension, the audio level of the audio sample carried in the RTP
  packet.  In large conferences, this can reduce the load on an audio
  mixer or other middlebox which wants to forward only a few of the
  loudest audio streams, without requiring it to decode and measure
  every stream that is received.
