Wild Track

Location sound recorded without camera to capture ambient room tone and effects


Definition and Purpose

Wild tracks (wild sound) are audio recordings made on set—such as room tone, footsteps or environmental ambience—without picture rolling. Sound recordists capture wild tracks to fill in gaps, smooth edits and maintain audio continuity in post-production.

Workflow

After principal photography on a setup, the mixer records 30–60 seconds of room tone with all actors silent. Additional wild tracks—doors opening, prop movements—are recorded to provide isolated sound effects for precise editorial placement.

Importance in Post

Editors and re-recording mixers weave wild tracks under dialogue edits to mask jumps in ambient sound and prevent “audio holes.” Consistent room tone maintains listener immersion when cutting between takes or angles.
