Problem
A wardrobe change alters the lavalier mounting position and causes the replacement audio to sound different from the original scene.
Solution
Root Cause / Diagnostic:
Moving a lavalier capsule to a different chest position or altering fabric mounting during a wardrobe change alters the acoustic frequency response, proximity effect, and chest cavity resonance.
Actionable Fix:
1. Measure and record the exact capsule distance from the talent's chin (standard 15–20cm) and maintain identical mounting orientation (pointing upward or downward).
2. Use identical mounting accessories (e.g., URSA MiniMount or Rycote Overcover) and tape the capsule to the same fabric layer to prevent wardrobe friction.
3. Record 15 seconds of spoken test audio and analyze the frequency spectrum against master take audio using an RTA analyzer to verify tonal continuity.
Pro Tip:
Always record a clean 30-second room tone block after any wardrobe change so the audio engineer can match background noise floors seamlessly during dialogue editing.
