  • Prioritise intelligible dialogue
  • Use sound to connect shots and suggest space

Build from the essential sound

Start with dialogue or the key story sound. The audience must hear the line, knock or ring that causes the next action. Add room tone and atmosphere to make the location feel continuous, then consider music. If every layer competes at the same level, the important event can disappear.

Choose atmosphere that belongs to the location and time: distant traffic, a refrigerator hum or rain beyond the window. Avoid adding effects simply because they are available. A quiet scene can gain tension from a small sound and a meaningful silence.

Listen across edits

Check that room tone does not drop abruptly at a cut and that the start of a line is not clipped. Use fades and level adjustments where the editing controls support them. Music should leave room for speech; a dramatic track cannot substitute for a clear performance or a readable action.

Use audio you own or are licensed to use, including voices and music. Watch the export with headphones and ordinary speakers if possible. Check captions against the actual spoken words. If a generated sound is wrong, decide whether to replace it in the edit or request a targeted new result rather than regenerating unrelated visuals.

Keep the café quiet under the dialogue. Let the doorbell interrupt the room tone, then leave a short pause before Nia answers. Bring in music only after she recognises the note.

Put it into practice

Write a sound plan with three layers: essential sound, atmosphere and optional music. Identify the one moment that should be quiet.

  • The important speech or cue remains clear
  • Sound changes across cuts feel intentional
