silentConcealedSamples

Last updated Applies toany rtcStats setup

The average number of concealed samples per second inserted that are 'silent'.

Description

Non-negative integer

MUST NOT exist for video (this is audio only).

The total number of concealed samples inserted that are "silent"

  • These are the muted portion of packet-loss concealment: when loss runs long, NetEq's Expand operation fades the synthesized audio toward noise or silence rather than voiced speech
  • This is a subset of concealedSamples
  • This is not DTX comfort noise. DTX, and the comfort-noise generation (CNG) it drives, are a separate operation and increment none of the concealment counters

Notes

  • Our preference is for this value to be as low as possible
