Properties

Property Type Description

Property	Type	Description
channel?	number	(Optional) The channel this reading is for, or undefined for a whole-stream reading.
data?	Uint8Array	(Optional) Packed binary payload for sample-feed taps (the goniometer’s interleaved i16 LE L/R pairs); undefined for scalar measurements.
pts	Interval	The media PTS the reading was taken at, as a rational (seconds). Lets a consumer correlate a reading with a point in the stream / compute rates.
source	string	The metric family, e.g. "rms".
tap	string	The tap’s name (as given to the op that produced it).
values	Record<string, number>	The named readings, e.g. `{ rms_db: -23.1 }`.
