The RTMS audio bytes (PCM — VERIFY the codec/sample-rate the deployment requests; the bridge forwards raw bytes regardless).
OptionalsizeOrTimestamp: numberEither the byte size (4-arg form) or the timestamp (3-arg form).
OptionaltimestampOrMetadata: number | RtmsMediaMetadataEither the timestamp (4-arg form) or the metadata (3-arg form).
Optionalmetadata: RtmsMediaMetadataThe metadata (4-arg form), carrying the diarization label.
The diarized inbound audio frame.
Pure mapping of one
@zoom/rtmsaudio callback invocation to the bridge's diarized ZoomAudioFrame ({ Pcm, ParticipantId, DisplayName?, TimestampMs? }). Isolated from the SDK and from I/O so it is unit-tested directly. Handles both documented callback arities and both payload types.
