An equalizer lets you boost or cut specific frequency ranges in your audio. Use it to add warmth by lifting the low end, bring clarity by boosting upper mids, tame harshness by cutting sharp frequencies, or sculpt a completely custom tonal balance. This parametric EQ gives you multiple adjustable bands, each with frequency, gain, and Q (bandwidth) controls.
Boost the 2-5 kHz presence range and cut low-frequency rumble to make speech intelligible in noisy recordings.
Apply gentle broad-Q adjustments to shape the overall tonal balance of a finished mix.
Cut a narrow resonant frequency caused by room acoustics that makes a recording sound boxy.
Roll off sub-bass below 40 Hz to clean up low-end rumble without affecting audible bass.
Add a high-shelf boost above 8 kHz to restore air and shimmer to a recording that sounds muffled.
Each EQ band is a filter that targets a frequency region. Gain controls how much that region is boosted or cut in decibels. The Q parameter sets bandwidth — a high Q affects a narrow slice of the spectrum, useful for surgical corrections, while a low Q creates broad tonal shifts. Shelf filters on the high and low ends boost or cut everything above or below a cutoff frequency, handy for overall tonal tilts. A well-set EQ can rescue a muddy recording or add presence to a flat voice track without introducing artifacts.
Q controls bandwidth. A high Q (e.g., 10) affects a very narrow frequency range, while a low Q (e.g., 0.5) creates a wide, gentle curve.
Cutting problem frequencies is generally cleaner than boosting. Boost when you genuinely need more of something; cut to remove what you do not want.
Boosting raises both signal and noise in that range. Cutting does not add noise. Keep boosts moderate to maintain a good signal-to-noise ratio.
Cut below 80 Hz to remove rumble, boost around 3-4 kHz for presence, and add a gentle shelf above 10 kHz for air.
