Sound effects are artificial or enhanced sounds used in various media, such as movies, television shows, video games, and theater. They help create a more immersive experience by adding realism or emphasizing certain actions. Common examples include the sound of footsteps, explosions, or ambient noises like birds chirping. These effects can be created using various techniques, including recording real sounds, manipulating audio digitally, or using synthesized sounds. Sound designers often work closely with directors and producers to ensure that the sound effects align with the overall vision of the project, enhancing storytelling and emotional impact.
