How do you access built-in sound effects in Final Cut Pro?

Accessing built-in sound effects in Final Cut Pro is done through the Sound Effects Browser. This specific browser is designed to provide users with a dedicated interface for browsing, searching, and previewing sound effects that come bundled with Final Cut Pro. When you use the Sound Effects Browser, you can quickly locate the audio clips you need by category, making it an efficient way to enhance your video projects with the right sound designs.

The alternative options involve different functionalities or sections of Final Cut Pro that do not specifically focus on sound effects. The Audio Settings are used to configure general audio preferences, the Project Library is mainly for managing your video projects and associated media, and the Media Inspector is utilized for examining and adjusting metadata of selected media clips. Thus, while each of those components plays an important role in the editing process, they do not directly facilitate access to sound effects like the Sound Effects Browser does.
