Cough sounds are easy to overdo and hard to hide in a mix. The fastest way to get a natural result is to decide what type of cough it is (dry, wet, restrained, strained), how close the listener is, and how much room tone you want behind it. Use the library for instant picks, then prompt the AI for small changes like softer attacks, longer decay, or different spacing between coughs.
Pick the cough type first
Most searches fail because the cough texture does not match the story beat. A dry cough reads like irritation or awkwardness, while wet chest coughs suggest illness. Strained coughs can feel older or exhausted, and a covered cough implies politeness or secrecy.
- Dry: sharp transient, short tail, less low-end
- Wet: more rasp and gurgle texture, longer decay
- Restrained: lower level, softened highs, less aggression
Match camera distance and space
A close cough with no reflections will feel pasted into a wide shot. Conversely, a distant cough with a long room tail can swamp a tight dialogue moment. Decide whether the cough is on-camera, off-camera, or in the next room, then choose the perspective that matches.
- Close-mic: clear attack, minimal room tone, narrow stereo
- Mid distance: some reflections, slightly reduced highs
- Distant: quieter transient, audible room tail and decay
Control timing and pacing
Editors usually need the cough to land on a pause, not fight the next line. Single coughs are best for quick interruptions, double coughs work for comedic beats, and coughing fits need natural gaps for breaths so they do not sound looped.
- Single cough: easy to place between words or breaths
- Burst coughs: tight spacing for emphasis without long tails
- Fit: varied spacing plus breaths so it feels human
Avoid common giveaway artifacts
Overly harsh sibilance, clipped transients, or mismatched background noise are the main reasons cough SFX feel fake. When prompting, ask for clean start and end, consistent room tone, and a controlled high end so it sits under dialogue and ambience.
- Avoid: loud mouth clicks or exaggerated throatiness
- Avoid: sudden room tone changes between takes
- Ask with softer attack, shorter tail, or less breath hiss
