Curve Device

Essentials

Curve is a precise 7-band parametric EQ with per-band frequency, gain, and Q, plus a real-time spectrum display for surgical and musical tone shaping. Designed for surgical tone shaping, mixing, and mastering applications.
  1. 7 fully configurable filter bands
  2. Per-band frequency, gain, and Q control
  3. Real-time spectrum display
  4. Surgical and musical tone shaping

The Curve EQ has 7 bands: 1 low pass, 1 low shelf, 3 fully parametric peak filters, 1 high pass, and 1 high shelf.

Cutoff Frequency Cutoff frequency of the filter (20 to 20000 Hz)
Slope

Filter slope:

  • 12 dB: 12 dB per octave
  • 24 dB: 24 dB per octave
  • 36 dB: 36 dB per octave
  • 48 dB: 48 dB per octave
Q Filter Q parameter, controls bandwidth and resonance (0.01 to 10)

Practical Tips

Practical Tips

  • Tame harsh resonances or frequency build-up.
  • Accentuate character frequencies in instruments or vocals.
  • Create space for other mix elements by cutting overlapping frequencies.
  • Apply tonal shaping during mastering for a polished result.
  • Explore creative filtering for sound design.
  • Narrow Q for surgical cuts; broader Q for musical boosts.
  • Solo bands to find problem areas or sweet spots.
  • Mastering: favor subtle moves to preserve integrity.
  • Stack small changes for natural results.
