SignalWire DocsParticipant represents a remote member on an active
WebRTCCall. Instances are
created by the call when members join and removed when they leave —
applications obtain them through
call.participants$,
not by construction.
Each participant exposes every per-member piece of state the SDK tracks: mute
state (audio/video), microphone processing flags (auto-gain, noise
suppression, echo cancellation), display name, hand-raise, talking detection,
sensitivity/volume levels, and current layout position. State is exposed in
two complementary forms — a snapshot getter (e.g.
audioMuted)
for one-shot reads and an observable (audioMuted$) for reactive UI binding.
Control methods (muteAudio, setMeta, toggleLowbitrate, etc.) issue
server-side requests scoped to this member. Their effect depends on the
caller’s capabilities — inspect the local
SelfCapabilities before
exposing controls in your UI. For the local participant — which adds device
selection, screen sharing, and local media stream control — use
SelfParticipant.
