Pick up where you left off.
The Frequency Spectrum
The frequency axis EQ works on, the named zones within it, and the difference between fixing a problem and shaping a character.
Filters
How high-pass, low-pass and shelving filters remove or shape frequencies, and the practical jobs they do in a mix.
Graphic vs Parametric
How graphic and parametric EQ shape the frequency content of audio signals, and when to reach for each.
Q & EQ Decisions
Q factor, signal routing, and the sweep-and-cut technique for finding and fixing problem frequencies in a real mix.
EQ Video Overview
Watch a cinematic overview of equalisation — filter types, graphic vs parametric EQ, and Q factor explained visually. Take notes as you watch.
