Exciter

An effect that adds harmonic content to enhance clarity and presence. By filtering the high-frequency content and applying saturation, it creates additional harmonics that brighten and enhance your music.

Listening Enhancement Guide

  • Subtle Enhancement:
    • Adds clarity and air to voices and high-frequency details
    • Enhances presence in the whole playback signal
    • Creates a more open, detailed sound
  • Moderate Effect:
    • Brings out hidden details in the mix
    • Adds sparkle and brilliance
    • Makes music sound more “hi-fi”
  • Creative Effect:
    • Creates bright, cutting tones
    • Adds aggressive presence
    • Useful when you want a brighter, more forward sound, but best used sparingly

Parameters

  • HPF Freq (500-10000Hz) - Sets the cutoff frequency for high-pass filtering
    • Low values (500-2000Hz): Affects more of the signal
    • Mid values (2000-5000Hz): Targets presence frequencies
    • High values (5000-10000Hz): Focuses on air and brilliance
  • HPF Slope - Controls the filter steepness
    • Off: No filtering, processes full spectrum
    • 6dB/oct: Gentle filtering
    • 12dB/oct: Steeper filtering
  • Drive (0.0-10.0) - Controls saturation intensity
    • Light (0.0-3.0): Subtle harmonic enhancement
    • Medium (3.0-6.0): Notable brightness
    • High (6.0-10.0): Strong excitation
  • Bias (-0.3 to 0.3) - Adjusts saturation asymmetry
    • Zero: Symmetrical saturation
    • Positive/Negative: Adds asymmetric character by changing which side of the generated enhancement saturates more strongly
  • Mix (0-100%) - Controls how much of the generated harmonic enhancement is added to the original sound
    • Low (0-30%): Subtle added brightness
    • Medium (30-60%): Clearer presence and detail
    • High (60-100%): Strong added harmonics; use carefully to avoid harshness

Visual Display

  • High-pass filter frequency response graph
  • Saturation transfer curve visualization
  • Clear visual feedback for both filter and saturation

Music Enhancement Tips

  • For Clearer Voices in Songs, Podcasts, or Videos:
    • HPF Freq: 3000-5000Hz
    • HPF Slope: 6dB/oct
    • Drive: 2.0-4.0
    • Bias: 0.05 to 0.1
    • Mix: 20-40%
  • For Clearer Mid/High Detail in Busy Recordings:
    • HPF Freq: 2000-4000Hz
    • HPF Slope: 12dB/oct
    • Drive: 3.0-5.0
    • Bias: 0.0
    • Mix: 30-50%
  • For Subtle Full-Track Brightness:
    • HPF Freq: 5000-8000Hz
    • HPF Slope: 6dB/oct
    • Drive: 1.0-3.0
    • Bias: 0.0 to 0.1
    • Mix: 10-25%

Quick Start Guide

  1. Set HPF Freq to target the desired frequency range
  2. Choose HPF Slope (start with 6dB/oct)
  3. Begin with moderate Drive (3.0)
  4. Set Bias near 0.1 for a slightly asymmetric character
  5. Set Mix to 25% and adjust to taste
  6. Fine-tune all parameters while listening
