An actor's dialogue naturally reaches the lav mic before the boom (excluding any electronic latency), giving us cues about distance. Tools like Auto-Align Post by SoundRadix help us dynamically align signals for constructive phase relationships, accounting for changing distances between microphones and the source as actors move and camera angles shift. This results in clean, rich sounds that combine lav clarity with boom depth. However, one could argue that this can reduce the sense of space or distance and can inadvertently diminish the natural perspective and ambience of dialogue. Tools like this and de-reverberation plugins allow us to manipulate perspective, proving handy under time constraints, which is why they're widely used and why many of us love to have the options. Yet, we must remember that every sound decision is a trade-off. Consistency and contribution to the story and emotion should guide our use of such tools. This raises the question:
