What is the definition of Calibration Sounds?

Calibration sounds, my friend, are the harmonious, rhythmic symphony that occurs when a device's audio output matches its intended sound. Picture this: a tiny, electronic monkey trying to mimic a human voice but somehow managing to produce a cacophonous mix of squeaky keyboard noises and grating metal. It's like it's auditioning for a new role in "The Office" but with microphones as props and a bad hair day.
