Prompt Influence

Control how literally the model interprets your description:

Value	Effect	Best For
0.0	Very loose interpretation	Creative, surprising results
0.3	Balanced (default)	General purpose
0.7	Close to description	Specific sound needs
1.0	Very literal	Exact sound reproduction

# Loose interpretation - creative result
belt app run elevenlabs/sound-effects --input '{
  "text": "Magical fairy dust sparkle",
  "prompt_influence": 0.1
}'

# Literal interpretation - precise result
belt app run elevenlabs/sound-effects --input '{
  "text": "Single gunshot, pistol, indoor range",
  "prompt_influence": 0.8
}'

Prompt Tips

Be specific: "Heavy rain on metal roof" > "rain sound"

Include context: "Footsteps on gravel, slow walking pace" > "footsteps"

Describe mood: "Eerie wind howling through abandoned building" > "wind"

Specify material: "Glass shattering on concrete floor" > "breaking glass"

Workflow: Add SFX to Video

# 1. Generate sound effect
belt app run elevenlabs/sound-effects --input '{
  "text": "Dramatic reveal swoosh with bass drop",
  "duration_seconds": 2
}' > sfx.json

# 2. Merge with video
belt app run infsh/media-merger --input '{
  "media": ["video.mp4", "<sfx-url>"]
}'
