Frequency
Frequency refers to how fast a sound wave vibrates and is heard as pitch.
Level relevance: introduced at Nat 3; tagged for every later level where the same concept remains useful.
Explanation
Frequency is measured in hertz and describes how many times a wave vibrates each second. Higher frequencies are heard as higher pitches and lower frequencies are heard as lower pitches. Frequency is important in EQ work because different parts of a sound occupy different frequency ranges. Understanding frequency helps when solving muddiness, harshness, or lack of clarity in a mix.
