Why I built AMB Digital: ten precision plug-ins that draw what they do to your audio

Prism EQ from AMB Digital

AMB Analog gives you character. AMB Digital gives you control, and it does it by refusing to let you guess. Every one of its ten plug-ins opens on a live picture of your audio, the spectrum, the curve, the bands, the echoes or the space, and the picture is the control. Drag a node, a crossover, a threshold or a delay tap, and the panel underneath follows.

What is in it

In the order a mix uses them. Prism EQ, a precision equaliser with up to 24 bands in eight shapes, each placed in stereo, mid, side, left or right, with the curve drawn over the live spectrum and dynamic bands if you want them. Flux Dynamic EQ, up to twelve bands that sit flat until the signal crosses their threshold, with an adaptive mode that follows the program level and an external sidechain. Spectra Multiband, two to six bands of dynamics over the spectrum, compressing or expanding up or down with a minimum or linear-phase split. Pulse Limiter, a true-peak limiter that shows exactly how hard you are hitting it with a scrolling history of input, output and gain reduction. Air De-Esser, which draws the reduction it is actually applying, measured from the audio. Resonance Ctrl, which tames resonances inside a range you set and shows you it is working on the honk and not the body. Freq Shaper, harmonics in six zones so you can put weight into a bass without touching the top. Orbit Delay, a main echo plus up to eight taps you place by hand, with tape-style pitch bends when you change the time and ducking while you sing. SpaceVerb Pro, a true stereo reverb where two seconds means two seconds, from 0.1 to forty. Wide Imager, five bands of width with bass mono underneath, a vectorscope, a correlation meter and a one-click mono check.

Ten numbered tiles in mix order: Prism EQ, Flux Dynamic EQ, Spectra Multiband, Pulse Limiter, Air De-Esser, Resonance Ctrl, Freq Shaper, Orbit Delay, SpaceVerb Pro and Wide Imager.

Eight of the ten add zero latency. The two that add some, the limiter's lookahead and the multiband in linear-phase mode, report it to the host. There are 120 presets, twelve in every plug-in, filed by source and shipped inside the plug-ins.

The problem it solves

Most mixing mistakes are made blind: a cut where the problem is not, a de-esser that is working on the wrong band, a reverb whose "2 s" is nothing of the sort. When the tool draws what it is doing from the real audio, you learn faster and you miss less. That is what I wanted on my own sessions, and what I wanted on the screen when I teach.

What else is out there

The precision tools people reach for are usually bought one at a time, and each one costs several times the price of this whole bundle. They are superb and I have used them for years. AMB Digital is ten of those jobs, drawn over your audio, for $39, with VST3, AU and standalone on both platforms.

Eight plug-ins listed at zero samples of latency, the limiter and the multiband in linear-phase mode marked as reported to the host, and the price of 39 dollars.

Who it is for

Engineers who want to see what a move does before trusting it. Anyone learning to mix, because the picture teaches. Mastering jobs that need a true-peak limiter and an honest reverb. Podcast and voice work, which lives on the de-esser and the resonance controller.

Price and licence

$39, once. VST3 and standalone on Windows 10 and 11, VST3, Audio Unit and standalone on macOS, Apple silicon and Intel. One key unlocks all ten on two computers, thirty days offline. The Mac installer is notarized by Apple. The Windows installer is not code signed yet, so SmartScreen warns the first time; choose More info, then Run anyway. The AMB Digital key is separate from the AMB Analog key.
