# How do the audio-capable world-model papers measure that sound stays in sync with actions, camera motion and events, and what do they leave unmeasured?

Three different measurement designs exist. AVWM compares the audio-energy vs motion-energy cross-correlation lag and peak of generated audio with that of ground-truth audio against the true visual trajectory (simulator data, 0.15 s steps); HelixBench (1,015 clips) scores DeSync on an Event subset and a Grounding-DINO-based three-region stereo score for camera-aligned panning; MaineCoon reports an unexplained "AV-Al" column where it is behind Ovi. Each protocol scores windows or short rollouts; none of the texts read measures the delay from a user action to the sound onset.

Curator qualifications: Excerpted evidence located (one excerpt-less row); HelixWorld claims vs higher DeSync of its causal student kept.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
