2. Sound-Effect Tags

Add simple Foley or ambient cues directly in the text:

Example

[gunshot], [applause],  [clapping],  [explosion], [swallows], [gulps], [binary beeping]

Feel free to experiment - engine will attempt to simulate common onomatopoeic sounds.

3. Prompt Crafting Tips

Tag placement matters - put the tag immediately before the word or phrase it should affect.
Stack tags sparingly – one or two per sentence keeps delivery natural.
Use punctuation for polish – ellipses, commas, and CAPS subtly tune rhythm and stress.
Think scenes, not sentences – write as if you’re directing an actor.
