What is a sound effect that is edited to match the screen?

• A. Lavalier Mic
• B. Hard sound effect
• C. Jam synch
• D. Layback

Answer: (B)

Hard sync is the idea here: a sound effect is edited so its onsets line up exactly with what’s happening on screen. When the visual action occurs, the audio hit lands at the same frame, sometimes even matching the exact transient of the sound. This precise timing makes the action feel real and impactful because the audience subconsciously expects the sound to come from the thing they see.

Lavalier mic refers to a microphone used to capture dialogue, not to editing SFX to the screen. Layback is the process of delivering the final audio mix to the picture, not the alignment of a specific sound effect to a visual moment. The term “jam synch” isn’t a standard description for this practice.
