Class: EchoGuard

Defined in: src/transport/echo-guard.ts:120

Per-session echo suppressor. Feed every OUTBOUND audio chunk through feedReference and run every INBOUND chunk through check; a suppress: true result means the inbound chunk is (part of) the assistant's own playback echoed back and should not be forwarded to the model or STT.
