Film and Audio Post-Production Practice Test

The idea here is to layer ambient, natural room sound to create a sense of space and to smooth over edits or inconsistencies. This term refers to backgrounds, which include room tone and other subtle ambient noises that sit under the main audio. By embedding these ambient sounds, the scene feels more cohesive, and cuts or mic differences become less noticeable because there’s a consistent sonic bed behind the dialogue or effects. It’s not about video footage (B-Roll), re-recorded dialogue (ADR), or frame-rate conversion (3:2 pull-down).
