I see 'subtractive EQ' everywhere. Is boosting bad?

In modern audio engineering, the rule of thumb is 'cut for fixes, boost for flavor.' Cutting is subtractive and helps clean up a mix without eating up digital headroom, while boosting is additive and should be used sparingly to draw attention to the best parts of a sound.

What to do
  1. 1.Prioritize cutting first to remove 'boxiness,' 'mud,' or 'harshness,' which creates natural headroom for other instruments to breathe.
  2. 2.Boost only after the signal is clean to enhance the desirable character or 'vibe' of the sound, such as adding 'air' to vocals or 'thump' to a kick.
  3. 3.Apply the 'Boost and Sweep' technique by creating a narrow boost, sweeping through the frequency spectrum to find offensive tones, and then flipping that boost into a cut.
Common mistakes
  • ร—Excessive boosting can cause digital clipping or phase distortion, making the track sound 'smeary.'
  • ร—Avoid EQing instruments in solo for too long; a sound that sounds great alone might disappear or clash once the full mix is playing.
Pro tip

Use a 'narrow Q' (high bandwidth) for cutting harsh resonances and a 'wide Q' (low bandwidth) for boosting musical character to keep the sound natural.
