Curve (EQ)

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.

  • 7 fully configurable filter bands

  • Per-band frequency, gain, and Q control

  • Real-time spectrum display

  • 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.

Low/High Pass Filters

Curve Low/High Pass Filters

Cutoff Frequency

Cutoff frequency of the filter (20-20000 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 (0.01-10)

Peak Filters

Curve Peak Filters

Frequency

Sets the center frequency of the EQ band

Gain

Boosts or cuts the amplitude at the selected frequency

Q (bandwidth)

Controls the width of the affected range; higher Q = narrower

Shelf Filters

Curve Shelf Filters

Frequency

Sets the shelf frequency

Gain

Boosts or cuts the amplitude at the shelf frequency

Output

Curve Output

On/Off

Activates or bypasses the equalizer effect

Post Gain

Output level after EQ processing (-inf to +24 dB equivalent)

Spectrum display

The real-time spectrum analyzer shows frequency content with three display modes:

Off

No spectrum display

Pre

Shows input signal before EQ processing

Post

Shows output signal after EQ processing

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.
