## Description

Describes what combination of input inference modes an `RTAnimationTracker` is

| `Audio` | 1 | Only audio-to-curve (lipsync) inference is active; no camera-based facial tracking is running. |
| `Video` | 2 | Only video-to-curve facial tracking is active; audio-based lipsync inference is not running. |
| `AudioVideo` | 3 | Both audio-to-curve lipsync inference and video-to-curve facial tracking are active simultaneously. |
