Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨August 2022⁩.

The silentConcealedSamples property of the RTCInboundRtpStreamStats dictionary indicates the total number of silent concealed samples for the received audio track over the lifetime of this stats object.

A concealed sample is a sample that was lost or arrived too late to be played out, and therefore had to be replaced with a locally generated synthesized sample. A silent concealed sample is one where the inserted sample is either silent or comfort noise.

Note: The value is undefined for video streams.
