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