Filters - Shaping Frequency

Filters sculpt your sound by removing frequencies. Turn harsh oscillators into warm pads, or thin out muddy bass.

How Filters Work

Filters let certain frequencies through while cutting others. The cutoff determines where filtering begins.

The Three Essential Filter Types

Low-Pass (LPF)

  • Lets lows pass, cuts highs
  • Sound: Warm, dark, smooth
  • Use: Bass, pads, smoothing

High-Pass (HPF)

  • Lets highs pass, cuts lows
  • Sound: Thin, bright, airy
  • Use: Space, clarity, effects

Band-Pass (BPF)

  • Keeps middle range only
  • Sound: Focused, nasal, vocal
  • Use: Resonance, formants
