EQ Tips

Cut before boost — subtractive EQ is more transparent than additive.

Use narrow Q for problem frequencies, wide Q for tonal shaping.

High-pass filter at 30–80 Hz on most tracks to remove sub rumble.

The 200–500 Hz range is where most mixes get muddy — cut strategically.

Boost 8–12 kHz for air, but watch for noise and harshness.
