Cue tone

A cue tone is like a signal that tells you when something important is about to happen. It's kind of like the sound that a bell makes in a school to let you know that it's time to start class or the beep that your computer makes when it's finished doing something. But in more technical terms, a cue tone is a specific sound that is used to mark the beginning or end of a recording, or to indicate something important within the recording. It's often a simple, repetitive sound that is easy to recognize, kind of like a musical note that plays over and over again. So when you hear a cue tone, you know that something important is about to happen, and you can pay attention to what comes next!
