You have arrived at the page for the Amber 4 Ultra plug-in suite created by Acustica Audio.
The newest release from Acustica Audio utilizes their Hyper technology and updated Aria engine to offer an improved version of their well-known Amber 4 plug-in suite. Amber 4 Ultra features accurate models of Class A equipment such as EQs, a compressor, and preamp, with upgraded visuals and better audio quality.
The suite includes two EQ plug-ins called Amber 4 Ultra and Amber 4 Stereo Ultra. Both have the same controls, but the Stereo version has separate controls for each channel. Each plug-in has four bands with frequency and gain controls. The low- and high-mid bands have a width parameter, while the low- and high-frequency bands have a control to switch between peak and shelf filter types.
Amber 4 Ultra comes with a continuous control function that allows users to focus on mid, left/right, and side signals. On the other hand, Amber 4 Stereo Ultra offers separate control over the left/mid and right/side channels. According to Acustica, the former is seen as a highly effective parametric EQ with low noise in the digital realm, while the latter is considered one of the most musically transparent EQ choices in their lineup.
The Amber 4 Comp Ultra simulates a Class-A opto compressor using Hyper technology to create a dynamics processor that is transparent. It includes typical compressor controls as well as extra features like side-chain filtering, adjustable stereo linking, a blend control for mid, left/right, and side signals, and built-in parallel compression.
Amber 4 Pre Ultra completes the collection with at least eight imitations of Class A preamp designs. There are both solid-state and valve-based units available, each with an easy-to-use set of controls for input and output levels, as well as Preamp (gain) and Filter (high-pass).
With the introduction of the Aira engine, all of the plug-ins now have the ability to display dynamic and real-time metering, as well as use the company's Anti-Aliasing algorithm. Additionally, they have improved CPU efficiency compared to the older versions.

Amber 4 Ultra can be used on computers with Windows 10 or 11, and Macs with macOS 10.15 or newer. It is compatible with VST2, VST3, AU, and AAX plug-in formats.
