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]
This document is a product of the Audio/Video Transport Extensions Working Group of the IETF.
This is now a Proposed Standard Protocol.
STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements. Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
status of this protocol. Distribution of this memo is unlimited.
