Is Gullfoss the same as soothe? It’s a common question, because both plugins automatically and dynamically adjust frequencies to make mixes sound cleaner and more balanced. But Gullfoss by Soundtheory and soothe2 by oeksound work in different ways and solve different problems. Understanding the difference helps you pick the right tool and avoid over-processing.
Note: the plugin is spelled “Gullfoss,” after the Icelandic waterfall, though it’s often misspelled “Gullfloss.”
Quick Answer
No, they aren’t the same.
- soothe2 is a dynamic resonance suppressor. It finds and reduces harsh, resonant peaks, and it only cuts.
- Gullfoss is an intelligent, adaptive EQ that improves overall tonal balance and clarity based on a model of human hearing. It can both cut (Tame) and boost (Recover).
How soothe2 Works
soothe2 analyzes the incoming signal and detects resonances, which are narrow frequency peaks that stick out. These often sound harsh, nasal or boomy. It then applies dynamic cuts only when and where those resonances occur, adapting in real time.
Common uses for soothe2:
- Taming harsh vocals and sibilance.
- Smoothing bright cymbals and distorted guitars.
- Reducing boxy or boomy resonances on acoustic instruments.
- Gentle de-harshing on buses or masters.
Its controls let you set depth, sharpness, selectivity, attack and release, and focus processing on specific frequency ranges. For a deeper look, read our soothe2 review.
How Gullfoss Works
Gullfoss uses a perceptual model of hearing to work out which frequencies are masking others or are being masked, then adjusts the EQ curve continuously to improve clarity. It has two main controls:
- Recover: boosts frequencies that are being masked, bringing out hidden detail.
- Tame: reduces frequencies that dominate and mask other parts.
Additional controls include Bias (which shifts the balance between Recover and Tame), Brighten and Boom. Because Gullfoss can add as well as remove energy, it’s often described as making mixes sound more open, clear and balanced.
Common uses for Gullfoss:
- Opening up a dull or cluttered mix bus.
- Improving clarity on full mixes and masters.
- Bringing out detail on dense buses such as drums or music.
Gullfoss vs soothe2: Key Differences
Purpose
soothe2 targets problems: resonances and harshness. Gullfoss targets overall tonal balance and clarity.
Boost vs Cut
soothe2 only cuts. Gullfoss can boost and cut.
Typical Placement
soothe2 is often used on individual tracks such as vocals, guitars and cymbals, as well as on buses. Gullfoss is most often used on buses and the master, though it can work on individual sources.
Sound
soothe2 sounds smooth and controlled, removing harshness. Gullfoss sounds clearer and more open, and can feel brighter or more detailed.
Can You Use Both?
Yes. Many engineers use soothe2 on individual tracks to clean up resonances, then Gullfoss on the mix bus or master for overall clarity. Because they solve different problems, they can complement each other. Use both with care: heavy settings on either can make a mix sound processed, lifeless or unnatural.
Tips for Using Them Well
- Start subtle. Small amounts often give the best results.
- Level-match when bypassing so you’re judging tone, not volume.
- Check transients. Over-processing can dull attack and punch.
- Fix big problems with EQ first. Neither plugin replaces good arrangement and mixing.
- Compare with references to make sure you’re moving in the right direction.

Alternatives
Other resonance suppressors exist, such as Baby Audio’s Smooth Operator. Compare it in our Smooth Operator vs soothe2 article. You can also use a dynamic EQ for more manual control over specific frequencies.
Which Should You Buy First?
If your main problem is harshness, such as piercing vocals, fizzy guitars or bright cymbals, start with soothe2 or a similar resonance suppressor. If your mixes sound generally dull, cluttered or lacking clarity, Gullfoss may make a bigger difference.
Before buying either, try the free trials and test them on a few of your own mixes. Listen at matched levels and bypass often. Many producers find that one tool suits their workflow far better than the other, and that improved arrangement and EQ skills can reduce how much they need either.
A Simple Workflow Using Both
- Balance and EQ your mix as usual.
- Add soothe2 to harsh sources, using just enough depth to tame the problem.
- Add Gullfoss to the mix bus at gentle settings.
- Compare against references at matched levels.
- Reduce settings if the mix starts to sound flat or overly bright.
How Each Plugin Affects the Mix Bus
On a mix bus, soothe2 at low settings can smooth harsh upper mids and tame boomy notes without dulling the mix. Gullfoss tends to change the overall picture more, adding clarity and openness. If your mix already sounds balanced, light Gullfoss settings may be enough. If it sounds harsh, soothe2 may be the better fit. In both cases, A/B at matched levels is essential, because both plugins can trick your ears into hearing “better” when they’re just different.
Frequently Asked Questions
Is Gullfoss better than soothe2?
Neither is better overall. soothe2 is better for removing resonances and harshness, while Gullfoss is better for improving overall clarity and balance.
Can soothe2 boost frequencies?
No. soothe2 only applies dynamic cuts to resonances.
Should I put Gullfoss on my master?
It’s commonly used on the master or mix bus, but use subtle settings and compare carefully with bypass at matched levels.
Is “Gullfloss” the correct spelling?
No. The correct spelling is Gullfoss, named after the waterfall in Iceland.
