Why Silk
HF air with mid/side control — not another generic shelf.
Maag-inspired air
A wide, smooth HF lift that breathes life into dull sources without sounding processed — the character engineers chase from legendary hardware, in software.
True mid / side
Enhance the center and stereo field independently. Separate voicings tuned for what each channel needs — firm focus in the mid, shimmer and width on the sides.
Adaptive harshness protection
The Protect circuit watches the 3–9 kHz region and backs off when enhancement gets too edgy relative to your source — push Amount further without fatigue.
2× and 4× oversampling
FIR half-band filters for alias-free HF enhancement. At 4×, Silk runs up to 192 kHz internally; latency is reported for full DAW compensation.
Under the hood
Presence without harshness
The air band, modernized
Engineers reach for the Maag EQ4 when a vocal needs to breathe or a mix feels closed-in. Silk brings that broad, gentle lift above 10 kHz to every track — dimensionality, not just brightness.
Not just a high shelf
A three-stage enhancement cascade — subtle presence shaping, a warm HF shelf, and a broad air peak at the top — adds space so the mix opens up and floats instead of simply getting louder up high.
Mid/side from the ground up
The entire chain runs in M/S. The center gets firmer, more focused enhancement; the sides get more shimmer and width. The Width control sets how much of that stereo depth you want.
See what you are hearing
A real-time spectrum overlays input and output with peak hold, clip indication, and pre/post traces — plus the ideal response curve at your current settings so you know when you have crossed the line.
Good fit?
Silk is for mixes that need height, width, and air — without brittle hype.
Vocals, mix bus, guitars, strings, and drum rooms that need air and width without brittle hype.
Sources where generic “air” shelves sound harsh or two-dimensional — you want lift that stays musical.
Anyone who works in mid/side and wants HF enhancement that respects the center vs the sides.
Engineers who want honest A/B (Auto Gain) and oversampling they can scale from the mix bus to multi-track sessions.
Replacing a full channel strip or fixing severe resonances and mud — that is what cleanup tools like Gloss are for.
Mono sources that never benefit from stereo width — Silk is built for stereo enhancement.
People who want a one-knob loudness solution; Silk is about tonal air and image, not mastering level.
Before & after
Where producers reach for Silk first.
Vocals
Lead vocals need presence and clarity — consonants that cut without sibilance, an airy top that feels natural.
Dull or boxed-in highs on the verse
Air boosts elsewhere feel harsh fast
Silky HF lift in mid and side independently
Protect reins in 3–9 kHz when the source pushes back
Mix bus
The “open the ceiling” move — gentle Amount with Width to extend the stereo image upward and outward.
The mix feels finished in level but not in height
Stereo width and air are hard to balance safely
Safe Ceiling soft-limits M/S while you experiment
4× oversampling keeps HF enhancement clean where it matters most
Early feedback
From early access users
“I have been looking for a plugin that sounds like my EQ4 rack unit for years. Silk is the first one that actually does.”
“The harshness protection is unlike anything else out there. I can push vocals harder than I ever could on hardware.”
“That analyzer makes it impossible to over-process. You see exactly when you have crossed the line.”

Concerns
Fair questions, straight answers.
Is this just another brightener?
Silk is a three-stage HF cascade with M/S processing and Protect — not a single shelf with a fancy skin. The goal is dimensionality and air that floats, not extra loudness above 10 kHz.
Will it work in my DAW?
Silk ships as VST3 and AU on macOS 10.13+ and Windows 10+, 64-bit stereo. Latency is reported to the host for automatic compensation at every quality setting.
Is it heavy on CPU?
At 4× oversampling Silk does serious work on the mix bus. On dense sessions, drop to 2× or Off — the dry path stays phase-coherent and many tracks will not need maximum oversampling to sound great.
Does it send my audio anywhere?
No. All processing runs locally. No uploads, no account required for the trial, and no iLok.
