Headrush Utility
Noise Filter
Inspired by HeadRush® Original
Advanced dynamic noise reduction effect (dual-threshold) more sophisticated than a classic gate:
- more natural behavior
- fewer “clean cuts”
- best for clean and ambient
GENERAL FUNCTION
- Reduces noise without brutally shutting down the signal
- USA two thresholds (Hi + Lo) for a smoother transition
Result:
- fewer artifacts
- more naturalness
- better sustain
Control Parameters
Hi ThreshdB
- Upper threshold
Function:
- level above which the signal passes completely
Behavior
- low: always open
- medium: natural
- high: more selective
When the signal exceeds this level → 100% open
Lo ThreshdB
- Lower threshold
Function:
- level below which the signal is attenuated
Behavior
- low: less intervention
- medium: natural
- high: more aggressive
Below this level → reduced noise
Attackms
- Opening time
- Behavior
- low: immediate
- medium: natural
- high: soft
Releasems
- Closing time
Behavior
- low: fast
- medium: natural
- high: slow
Pro Tips
- Hi too high → loss of attack
- Lo too high → gate effect
- Low attack → click possible
- Low release → unnatural cut
Basic trick:
- keep Hi > Lo (by 10–20 dB)
Workflow:
- set Lo
- Hi rule
- fine-tune Attack/Release
Quick Reference
- Hi Thresh (dB): full opening
- Lo Thresh (dB): attenuation
- Attack (ms): entrance
- Release (ms): exit
