What is a cue sheet and what is it used for?

A cue sheet is a document that outlines the timing and content of audio or visual media, typically used in film, television, and radio productions. It lists cues for sound effects, music, dialogue, and other elements, along with their corresponding timestamps. Cue sheets are essential for ensuring synchronized audio-visual production, facilitating post-production processes, and managing licensing and royalty payments for music usage. They help maintain organization and clarity throughout the production workflow.
