# Create Custom Sound Effects with AI

> Generate custom sound effects from a text description using Artnex VoiceZen. Produce unique SFX for games, videos, and podcasts in up to 22 seconds.

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.

## Navigate to Sound Effects

Go to **Tools > Audio > VoiceZen > Sound Effects**.

## Generate a sound effect

<Steps>
  <Step title="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`

    <Tip>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.</Tip>
  </Step>

  <Step title="Set the duration">
    Click the **duration button** (clock icon) and select how long the sound effect should be:

    | Duration   | Notes                             |
    | ---------- | --------------------------------- |
    | 2 seconds  | Short, punchy one-shot effects    |
    | 5 seconds  | Standard length for most SFX      |
    | 10 seconds | Extended effects or ambient loops |
    | 15 seconds | Long atmospheric textures         |
    | 22 seconds | Maximum duration                  |

    <Note>All durations cost **150 credits** per generation regardless of length.</Note>
  </Step>

  <Step title="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.
  </Step>

  <Step title="Generate">
    Click **Create**. The audio appears in the player when generation is complete.
  </Step>

  <Step title="Preview">
    Use the audio player to listen back before downloading.
  </Step>

  <Step title="Download">
    Click the download button on the player to save the file to your device.
  </Step>
</Steps>

## Credit cost

Sound Effects costs **150 credits** per generation, regardless of duration.
