Amplitude
Amplitude is the size of a sound wave and relates to how loud it appears.
Level relevance: introduced at Nat 4; tagged for every later level where the same concept remains useful.
Explanation
Amplitude describes the strength of a signal. In practical terms, greater amplitude is usually perceived as greater loudness. In a waveform display, louder sections often appear taller. Managing amplitude matters throughout recording and mixing because signals that are too low can be noisy, while signals that are too high can distort or clip.
