Soundtheory Gullfoss v1.11.6 ARM macOS screenshot
macOS | 6 April 2025 | 100 MB
Gullfoss is an easy-to-use tool for everyone from the amateur musician to the professional mastering engineer. Its clean user interface offers a set of basic parameters that can be adjusted to improve the clarity, detail, spatiality, and balance of a mix or recording in a matter of seconds.

Take control
Gullfoss is an intelligent equalizer that listens to a signal and decides how to prepare the audio so that your brain can get the most information out of it. The realtime analysis of Gullfoss uses Soundtheory’s computational auditory perception model to understand which audible elements are competing for your attention. Gullfoss allows for quick and precise fixes that would otherwise be unsolvable or would require significant time and experience to resolve.

Gullfoss is even capable of fixing balancing issues between different sound elements without access to the individual tracks. The internal auditory model allows Gullfoss to make objective decisions about the perceived sound. As a result, mixes processed with Gullfoss will generally translate more consistently between different listening situations.

Gullfoss, enabled by new patent-pending equalizer technology, processes audio with unrivaled sound quality. The equalizer is capable of changing its frequency response more than 300 times per second and without introducing audible artifacts or degrading signal quality. Together with the highly advanced computational auditory perception model that has been developed by Soundtheory, Gullfoss is the first and only product of its kind.

This installer is an AU updater only. It doesn't install any VST3 update (AU version shows v1.11.6 and VST3 shows v1.11.5).
y'all got anymore of those plugins??

AU is the only thing that showed up after scan. AU seems to work fine.
Not sure if it's the ARM process, but no go for the VST3.
M1 Big Sur 11.7.10 / FL 21.2.3
The above assessment holds true for Native, but the AU won't work in Intel (Rosetta) and the VST3 didn't show up after an additional plugin scan in Intel mode.

* After checking my VST folder, it’s only the AU that is installed

But it and Kraftur work and that’s pretty cool.

Hey guys I have a validation issue with logic/Sonoma/ARM. It won't validate any gullfoss AU even after codesign... What should I try ? thx

PS: Kraftur works fine

Validate it again to see the output window why it's failing.
And check the auval crash log, maybe the plugin needs some extra libs.

It just says validation blocked. (Manufacturer Pass)

Nice, now I can finally test it out without crashes. Seems to work fine as intended.

Why do you want to use vst3 on a mac? logic, ableton, fl & studio 1 are all au compatible & with cubase you can use a wrapper

Doesn't work in my mac m3, sequoia and logic:

FATAL ERROR: OpenAComponent: result: -1,0xFFFFFFFF


validation result: couldn’t be opened

EDIT: ok managed to work:

1) uninstall previous version
2) install this version and don't open yet Logic for the validation
3) open terminal and write:

function prep() {
sudo xattr -cr "$1"
sudo xattr -r -d com.apple.quarantine "$1"
sudo codesign --force --deep --sign - "$1"
}

prep "/Library/Audio/Plug-Ins/Components/Gullfoss.component"
prep "/Library/Audio/Plug-Ins/Components/Gullfoss Live.component"
prep "/Library/Audio/Plug-Ins/Components/Gullfoss Master.component"

4) open logic and validation will work.

Please notice that sentinel doesn't work on this, so better to use terminal.

Hope it will help!

Please always state your exact Logic and macOS versions + Mac model if you want the community to be able to help you. Otherwise, it is tough to isolate what your particular issue might be.

Installed on top of the previous (magnificent) version shared here, and it's completely broken.

The previous version was already working flawlessly on M1 Native.

This one seems wrong, it broke everything for me:
"An audio unit has reported a problem," and causes lots of glitches when loading/opening a Logic session + When you open the plugin UI, it doesn't show anything.
Unistalling and reinstalling previous Audioz distribution fixed everything.

I recommend moderators and hidera to please revise it.

Thanks for your amazing shares, nonetheless! ALWAYS GRATEFUL!!

Tested in: Logic 11.1.2 ARM Native / macOS Sequoia 15.5 / MacBook M1 Pro 16" 2021

I'm having the same issues with this and Kraftur as with the Lexicon bundle - they install fine and pass Logic verification, but when you open them the screen is just a black box and no sound is passed through. I did a deep codesign on all of them.

Did you install this release over the previous release?

Edit: I had this problem and sorted it out with a clean install (the plugin, not the OS).

It's working fine here as an AU (Cubase with Bluecat's patchwork, M2 Macstudio, Sequoia),
it just needs codesign. Without it, Cubase just crashes.

Binary Information (from the similar Eventide bundle)

Please note: These plugins are released as ARM-only AU (Audio Unit) versions.

This decision was made because AU validation passes consistently and reliably under this architecture.
While we also tested VST3 builds, they proved stable only within Cubase.
The reason lies in how different DAWs handle plugin validation and security checks.

Soundtheory Gullfoss Changelog
v1.11.6 (2025-02-25)
• [WIN] Included a fix to support the Zen 5 architecture.
• Fixed the Boost parameter unit label.

Pointless if you want to use this on a Mac.

Edit:
My mistake. I thought it was just Win updates. I wonder what the "Fixed the Boost parameter unit label" is.

Looking inside the package I see all 3 components (Live, Regular and Master) - if anyone is wondering.

wow this did the trick,
DO you advise using this on everything here to assure things work if it does not harm?

Well, awareness of dequarantining and codesigning are part of the modern hygiene of this on apple silicon and have been for awhile...
