How to Generate Customized Sound Effects with Filmora
Here is a step-by-step guide for you:
Step 1: Launch Filmora and Create a New Project
After downloading Filmora, open the program and log in or sign up from the main menu. Next, go to the control panel on the left and click "Create Project." Then, choose the "New Project" tab from the menu that appears.

Step 2: Access the AI Sound Effect window
After selecting a new project, you'll be directed towards Filmora's main editing interface. From there, navigate towards the "Audio" tab in the top custom toolbar. Following that, hover towards the panel at the left, select "AI Sound Effect."

Step 3: Craft Your Prompt and Generate
The new interface provides powerful tools to help you create the perfect sound effect. You can either type your own description or use AI to get inspiration.
1. Describe Your Sound Effect
In the "Prompt" box, describe the sound effect you want to generate. Be as specific as you like. The prompt supports multiple languages and has a limit of 100 characters (or 50 Chinese characters).

If you need some creative help, use one of the new features:
- Use Creative Tags: Click on tags like Object, Abstract, Animal, Environment, or Human to get ideas and add relevant keywords directly into the prompt box.
- Generate with AI: If you're not sure what to write, click the "Generate with AI" button. The AI will suggest a creative and detailed prompt for you, which you can then use or edit.
2. Adjust Settings and Generate
Set the desired duration of sound effects you want to create. Once you are ready, click “Generate.”

Note:
All prompts are automatically checked for sensitive content to ensure a safe creative environment.Step 4: Obtain Results
You can preview, download, and apply the generated sound effects to the timeline.

You can view the downloaded sound effects in the "Downloads."

Note: The generated sound effect records can only be saved for 30 days. Therefore, if you are satisfied with the generated sound effects, please ensure you download and save them promptly.
