Pure Amber

Pure Amber is a Windows VST3 plugin for organic spectral shaping and resonance control.

I built Pure Amber because I was tired of resonance suppressors that surgically fixed my mix but sucked all the life and transient energy out of it in the process. Pure Amber is a high-resolution spectral dynamics processor that targets harshness and boxiness, but with a unique set of tools designed to keep your audio sounding human.

Whether you need to quickly tame a harsh vocal, transparently balance a drum bus, or push the spectral engine into weird, organic stereo widening, Pure Amber gives you the exact tools to do it without the usual plastic-sounding artifacts.

The Brains of the Operation

If you want to move fast, just hit Auto Pilot. It's not a gimmick; it's a multi-pass learning engine. It listens to your audio, uses temporal filtering to ignore your musical transients, and hunts down the persistent, annoying resonances. It tunes the parameters, builds a custom suppression curve, and applies it. It even double-checks its work—if a learning pass makes things worse, it automatically rolls back.

Complete Dynamic Control

Instead of just giving you a threshold, Pure Amber splits the detection and the punishment:

• Dosage: Your master intensity. Keep it below 1.0 for transparent, calculated cuts, or push it up to 2.0 to overdrive the suppression for aggressive tone shaping.
• Sensitivity & Resolution: Dial in exactly what the plugin reacts to. Lower the resolution to catch only the sharpest, most painful spikes, or raise it to smooth out wider buildups.
• Safe Vitals: The most important knob for your transients. This is a hard ceiling on how deep any single frequency bin can be cut. No matter how hard you push the Dosage, your core musical content stays protected.
• The Biopsy: A true delta mode. Hear exactly what Pure Amber is ripping out of your audio, and nothing else.

Bringing Life Back to Digital (Variation Modes)

Surgical EQ can sound unnaturally dead. If things get too sterile, flip on Min Phase / Variation Mode. This injects subtle, organic movement, like a sine wave, random noise, or a slow, wandering drift only into the frequency bins that are being actively suppressed. It fills the digital voids left by heavy processing, making aggressive cuts sound natural and alive.

Not Just for Mono-patibility

Switch Pure Amber into Mid/Side mode, and the entire engine changes behavior. Instead of standard L/R suppression, it uses the gain reduction data to drive frequency-selective stereo widening. It splits your audio into 8 bands of allpass decorrelation, automatically protecting your mono bass (0-283Hz) while dynamically pushing the harsh stuff out to the sides.

The Visualizer

The UI gives you completely freeform control over the suppression curve. Draw your limits directly on the 30fps spectrum display, tweak the tension handles to bend the curves exactly how you want them, or choose from 12 different curve shapes (from bells to sigmoid to steps). If you want to lock the shape and just ride the overall depth, hit the Gain Lock and drag the whole curve as one unit.

Runs in standard mode or with HD Imaging (2x Oversampling) for the cleanest possible processing.
