audio_config

Process-wide audio-encoding knobs.

The server resolves its audio settings once and publishes them here; the vendored WebRTC codec classes (constructed deep inside the codec factory, where no settings object reaches) read them at construction time. This module stays dependency-free so the WebSocket-only path can publish values without importing the WebRTC stack.

def set_red_distance(distance: int) -> None:
    """Publish the RED redundancy depth, clamped to non-negative."""
    global red_distance
    red_distance = max(0, int(distance))
