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 that wants to forward only a few of the
loudest audio streams, without requiring it to decode and measure
every stream that is received.  [STANDARDS-TRACK]
