Sound Effects generates custom audio clips from a plain-text description of the sound you want. Instead of hunting through stock libraries for something close enough, you describe exactly what you need and the AI produces it — from a thunderstorm to a laser blast to a crowd roar. Go to Tools > Audio > VoiceZen > Sound Effects.

Generate a sound effect

1

Describe the sound

Type a description of the sound effect in the prompt field. Be as specific as possible — include the type of sound, its character, and any contextual details.Examples:
  • Thunderstorm with heavy rain and distant rolling thunder
  • Laser gun firing with a high-pitched electric discharge
  • Crowd cheering in a large stadium, building to a roar
  • Wooden door creaking open slowly
  • Underwater bubbles rising to the surface
Click the Sparkles icon to automatically expand your description into a more detailed prompt. You can also open the Pencil icon for the full prompt editor.

Set the duration

Click the duration button (clock icon) and select how long the sound effect should be:
DurationNotes
2 secondsShort, punchy one-shot effects
5 secondsStandard length for most SFX
10 secondsExtended effects or ambient loops
15 secondsLong atmospheric textures
22 secondsMaximum duration
All durations cost 150 credits per generation regardless of length.

Adjust prompt influence (optional)

Click Settings to adjust the Prompt Influence slider (0–1). This controls how closely the generated audio follows your text description.
  • Low values give the model more creative freedom, which can produce unexpected textures.
  • High values keep the output tightly aligned with your description.
The default value of 0.3 works well for most prompts.
