What is the Threshold in Spectral Gate?
The Threshold controls which frequencies pass through and which ones get muted or reduced,
but instead of applying it to the whole signal, it works per frequency bin thanks to FFT.
When the energy of a frequency band is above the threshold, it’s allowed to pass.
When it’s below the threshold, it gets gated, meaning reduced or silenced.
This gives you precise, frequency-dependent control over what stays and what goes.
Why it is special?
Unlike traditional gates that affect the full signal based on overall volume, the Spectral Gate listens to every tiny slice of the spectrum and decides what to let through.
That means you can:
• Isolate transients
• Clean up noise or reverb tails
• Shape textures in a musical or aggressive way
Dial it low for a gritty, textured effect.
Dial it high to let only the strongest parts of the sound cut through.
What are Attack and Release?
Sets how quickly the gate opens when a frequency crosses the threshold
• Short attack = sharper, more responsive gate
• Long attack = softer fade-in, good for smoother textures or avoiding clicks
Sets how long it takes for the gate to close after a frequency falls below the threshold
• Short release = tight and choppy
• Long release = smoother tail-off, good for more musical or washed-out effects
What is Tilt ?
The Tilt (Brightness) control adjusts how the threshold behaves across the frequency spectrum, making the gate more or less sensitive to low or high frequencies. It’s like tilting a shelf-EQ, but instead of boosting or cutting sound, you’re tilting how aggressively the gate responds across the spectrum.
How it works:
→ Tilt to the right (positive values): Makes the gate more sensitive to low frequencies — lows get tighter and cleaner; highs are more open and airy.
→ Tilt to the left (negative values): Makes the gate more sensitive to high frequencies — brighter frequencies get gated more quickly; lows stay fuller and punchier.
What is Dry/Wet?
Dry/Wet controls the balance between the original signal (Dry) and the processed signal (Wet). It lets you blend how much of the spectral gating effect you want to hear.
How it works:
0% (Fully Dry):
→ You only hear the clean, unprocessed sound.
100% (Fully Wet):
→ You only hear the gated signal, fully affected by the spectral processing.
Anywhere in between:
→ Mixes both together — great for adding character without losing the original punch.
