Iron Glass Mastering EQ for VST3 AU AAX Available Now 2026-06-15T11:57:39+00:00 https://remanenceaudio.com/assets/iron-glass-banner.png Iron Glass is now a full plugin (VST3, AU, AAX) A few weeks ago, I posted a free JSFX version of Iron Glass on gearspace, only expecting a handful of downloads. I was honestly shocked by the feedback I got. I was already working on porting the plugin when I released the JSFX version, but development quickly took a different direction. The JSFX approximated analog behavior using stacked layers of interconnected DSP, which was a cool experiment, but didn’t end up giving the results I was going after. This version is built on several very accurate circuit models, so the tubes, both transformers, and inductor network are solved as actual circuitry rather than imitated. The payoff is the thing real hardware does, and most plugins do not. I don’t want to start rambling off adjectives that have a different meaning to each person, so I’ll let you decide how it sounds. What the plugin consists of:  Five parallel bands in a circuit modeled inductor network  Tube and iron stages with adjustable character. Think of these as changing the characteristics of the tubes and transformers, not how hard they’re being driven  High and low pass filters also solved as real inductors, not utility filters bolted on  ±18 dB of linkable input and output gain, which gives you control over how hard you wish to drive the circuit  Independent L/R or M/S processing  Oversampling to 192kHz internally with ADAA on the inductor network for additional antialiasing Why this approach and what makes it different: These are not fixed curves with saturation bolted on at the end. Nothing is a fixed response. The same EQ move behaves differently depending on how hard you drive it. Pushing the inductors hard will raise the frequency and cause the Q to drop slightly. I’m not cloning a specific piece of hardware. Each stage was tuned by ear. The transformers respond like transformers do. The iron remembers how it just saturated and settles in the moments after, and that memory is a big part of the depth and the feel after a transient. This phenomenon is where I got the name Remanence Audio from. Formats and systems:  macOS: VST3, AU, and AAX, universal binary for Intel and Apple Silicon, macOS 11 and later  Windows: VST3 and AAX, 64 bit, Windows 10 and later  Fully offline licensing, with a fully functional 14 day trial Iron Glass is available now from Remanence Audio at https://remanenceaudio.com for an intro price of $50 for the first two weeks, then $75 after. I look forward to hearing it on your music! leckel1996 https://www.kvraudio.com/forum/memberlist.php?mode=viewprofile&u=350466
