Struct CaptureOptions 

pub struct CaptureOptions {
    pub loopback: bool,
    pub processing: bool,
    pub level_only: bool,
}

What to capture and how to process it. All flags are orthogonal; defaults give you the full pipeline (mic + loopback + APM).

Fields

loopback: bool

Capture the default render (output) device via WASAPI loopback. Windows only — on other platforms the flag is ignored and capture runs mic-only.

processing: bool

Run the WebRTC audio processing module (AEC3 echo cancellation + light noise suppression) on the mic path. Requires webrtc-apm.dll on Windows; a missing dll degrades gracefully to unprocessed mic. No-op on non-Windows platforms.

level_only: bool

Emit only 10 Hz FrameEvent::Level events — no PCM, no loopback, no APM. For “level meter preview” UI that runs while idle: ~0% upload cost, <1% CPU.
