Gullfoss Soundtheory Review

Gullfoss is the perfect tool for anyone who wants to improve the quality of their audio recordings. Its clean user interface and easy-to-use controls make it ideal for both amateur musicians and professional mastering engineers. You can adjust the clarity, detail, spatiality, and balance of your mix or recording with just a few clicks.

The average person’s hearing is sensitive enough to detect a wide range of sounds, from the softest whisper to the loudest thunder. However, our auditory perception is far from perfect. We can often miss important sounds, mishear what others are saying, and struggle to filter out background noise.

Thankfully, our hearing can be developed and trained to improve these skills. Gullfoss is a great tool to help with this process. By wearing Gullfoss while working, studying, or watching television, you can train your brain to better focus on the sound you want to hear.

In addition, Gullfoss can help you learn to discriminate between similar sounds, such as different words or musical notes. With regular use, Gullfoss can help you to sharpen your auditory perception and attain greater control of your audio environment.

Gullfoss Waterfall

The Gullfoss Waterfall is one of the most popular tourist attractions in Iceland. The waterfall gets its name from the Icelandic word for “golden falls”, and it is easy to see why. The waterfalls over a series of three cascades, each more impressive than the last.

The first cascade is the largest, and it plunges into a deep gorge. The second cascade is smaller, but it has a more graceful curve. The third cascade is the smallest, but it is also the most beautiful, with a wide rainbow spanning its width.

Visitors to the waterfall can walk behind the cascade on a series of wooden walkways, or they can take a boat ride through the gorge. Either way, it is an unforgettable experience.

What’s more, Gullfoss is constantly being updated with new features and improvements, so you can be sure that you’re always getting the best possible sound quality. Whether you’re a beginner or a pro, Gullfoss is the perfect tool for anyone who wants to take their audio recordings to the next level.

Gullfoss by Soundtheory has been for the last weeks on the review bench in Cubase. Gullfoss is an unusual dynamic equalizer plugin that cleverly adapts the EQ parameter to improve the track or mix bus. Gullfoss is named after a waterfall in southwest Iceland.

There are plenty of great EQ plugins available, they all require mixing and audio knowledge that goes beyond a basic understanding of tone and layered instruments and sounds. Gullfoss is different with its automated EQ capabilities. Soundtheory did send a review copy with no strings attached.


Download the plug-in and install it by opening the disk image and then double-clicking the package. When you launch it the first time, you can use the ‘Authorize’ button to register EQ.

Just follow the instructions. On Cubase, I did experience a “hang” when authorized. I did need to relaunch Cubase, and all was fine. This error is reported to the developing company, and they are addressing it as we speak.

It is MAC only today (Feb 2018) a PC version of Gullfoss is planned for later in 2018.

Gullfoss Soundtheory Review

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.

Gullfoss can be used as a stand-alone application or as a plug-in for your favorite DAW. Whether you’re looking to add some sparkle to your acoustic guitar tracks or tighten up the low end of your mix, Gullfoss has the tools you need to get the job done quickly and easily. So why not give it a try today? You may be surprised at just how much of a difference it can make.

Gullfoss Real-Time Analysis

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 real-time analysis of Gullfoss uses Soundtheory’s computational auditory perception model to understand which audible elements are competing for your attention.

Generates Immersive Listening Experience

This allows you to hear details that you would otherwise miss, resulting in a richer and more immersive listening experience. Whether you’re listening to music, watching a movie, or playing a video game, Gullfoss will ensure that you are getting the most out of your audio.

Gullfoss is a state-of-the-art audio processing tool that can be used to improve the quality of sound mixes. One of the key features of Gullfoss is its ability to balance different sound elements without needing access to the individual tracks.

This is made possible by the internal auditory model, which 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. This makes Gullfoss an ideal tool for audio engineers who need to produce high-quality results on a consistent basis.

No Need for Manual Analyzing the Signal

If you’ve ever tried to mix a song with multiple tracks, you know how difficult it can be to keep all the different frequencies from clashing. Fortunately, there’s a new tool that can help: Gullfoss.

Gullfoss analyzes the signal and decides how to prepare the audio to minimize any confusion. Through the use of Soundtheory’s computational auditory perception model, Gullfoss helps you understand which audible elements are competing for your attention. This way, you can make sure that all the frequencies in your mix sound their best.

So if you’re looking for a better way to manage clashes between frequencies, check out Gullfoss. It just might be the solution you’ve been looking for.

As anyone who has ever tried to fix a hole in the wall knows, it can be a frustrating process. You start by trying to apply a bit of joint compound to the hole, but before you know it, the entire area is a mess.

And even if you do manage to get the joint compound to stick, it’s never quite the same as the surrounding wall. That’s where this plug-in comes in. With its precision tip, it allows you to quickly and easily apply joint compound to the hole. Plus, the built-in level ensures that your repair is perfectly aligned with the surrounding wall.

As a result, you can achieve a professional-looking finish that would otherwise be impossible.

Make Mixing and Mastering Decisions

Any serious audio engineer will tell you that EQ is one of the most important tools in the mixing toolbox. The right EQ can help to bring out the best in a track, while the wrong EQ can ruin even the most well-recorded song.

That’s why it’s so important to have a good EQ plugin, like the one mentioned in the topic. This particular EQ plugin is known for its accuracy and ability to paint a clear picture of the frequency response.

As a result, it can be a valuable tool when it comes to making informed mixing decisions. If you’re serious about getting the best possible sound out of your mixes, then this EQ plugin is definitely worth checking out.

There is no question that digital audio workstations have changed the face of music production. By providing a wide range of features and plugins, they have made it possible for anyone with a computer to create professional-sounding recordings.

However, this does not mean that DAWs are perfect. In fact, there are a number of drawbacks that can make them frustrating to use, particularly for beginners. One of the biggest problems is the steep learning curve. A DAW can be extremely complex, and it can take months or even years to learn how to use all of its features. Another issue is the high cost of many popular DAWs.

Even basic versions can be very pricey, which puts them out of reach for many aspiring engineers. Despite these drawbacks, DAWs remains an essential tool for anyone serious about music production. With a little patience and perseverance, anyone can learn how to use one effectively.

Using this plugin is very straightforward. For the master bus, you can brighten the overall sound of your mixes if you wish, or you can scoop a bit to get more clarity.

Patent-Pending Equalizer

Soundtheory’s new Gullfoss audio processing technology is unrivaled in terms of sound quality. The patent-pending equalizer is capable of changing its frequency response more than 300 times per second, without introducing any audible artifacts or degrading the signal quality.

Combined 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 means that it can accurately and effectively process audio signals to produce the best possible sound quality. In addition, the Gullfossequalizer is also extremely user-friendly, making it easy for anyone to get the most out of it. Whether you’re a professional musician or just an avid music lover, Gullfoss is sure to impress.

Gullfoss as an EQ plugin has one reason to exist. It automatically adjusts the EQ settings based on the audible features of the input signal. Gullfoss approach is to provide an instant improved quality of the track. Tracks that you could not fix due to lack of experience or knowledge.

Gullfoss Soundtheory Review

Gullfoss processes audio with a unique character. According to the developer, the EQ can change its frequency response more than 100 times per second without introducing audible artifacts or degrading signal quality.

As this plugin should help all the not so experienced composers and mix engineers this could be a killer tool for the amateur who wants to focus on something else than mixing and still want to do everything in the home studio.

For a professional audio engineer, Gullfoss is a great way to see and compare the “robot” changes to her or his result.

If you experience that the sound is a bit harsh drive down the settings within Gullfoss with the lower values, and you tend to get the wanted EQ effect.

I did get some good-sounding tracks and also tried it on the mix bus and was surprised by the excellent quality. If you are in a hurry or lack the experience of using an EQ in your DAW, you get better results than turning knobs in a traditional EQ while you do not know what those labels and dials mean.

Gullfoss Features:

  • Automatic equalization in real-time
  • A highly advanced computational auditory perception model makes objective processing decisions
  • Intelligently treats sound elements in the mix separately
  • Improves clarity, detail, spatiality, definition, and presence
  • Eliminates annoying resonances and cancellations
  • Retains dynamics and reduces the need for multiband compression
  • Mixes translate much more consistently between listening environments
  • Improve your mixes by watching the real-time EQ graph display

User interface & Usability

With a rather simple Interface, you drive the level of “automation” and that is all you need to do. You can download the manual here.

A spectrum analyzer is a tool used to visualize and analyze the frequency content of audio signals. In music production, spectrum analyzers are used to help identify problem areas in recordings, optimize sound systems, and troubleshoot technical issues.

At first glance, the interface of most spectrum analyzers can appear daunting to those who are new to digital audio. However, even if you have no prior experience with spectrum analyzers, the interface of most plug-ins is clear enough to be intuitive and easy to use if you have a basic understanding of how frequencies work. In general, spectrum analyzers display the amplitude (loudness) of a signal at each frequency within a given range.

The human ear can perceive sounds in the frequency range of 20 Hz to 20 kHz, but some sounds outside of this range may be picked up by microphones and other recording devices. In addition to displaying the amplitude of a signal at each frequency, many spectrum analyzers also provide other features such as real-time analysis, spectral averaging, and filter options.

Whether you are new to digital audio or an experienced engineer, a spectrum analyzer can be a valuable tool for visualizing and analyzing the frequency content of audio signals.

Gullfoss Meters

The Gullfoss meters are a great way to get an idea of what’s going on in your signal. The horizontal meters below in the frequency spectrum graph show how much the signal is being brightened or dimmed. The brighter the signal, the more power it has. If the signal is dimmed, it means that it doesn’t have as much power.

The left and right sides of the graph represent the high and low frequencies, respectively. The further away from the center of the graph, the higher or lower the frequency. The meter at the top shows the overall level of the signal, while the bottom meter shows the level of background noise.

By using these meters, you can get a better idea of how your signal is performing and make adjustments accordingly.


To start with, Gulfoss is an EQ plugin that is specifically designed for live sound applications. What this means is that it has been created with the intention of being used in a live setting, where you need to be able to make quick and accurate adjustments on the fly.

This is in contrast to most other EQ plugins, which tend to be geared more towards studio use. As a result, Gulfoss offers a number of features that make it ideally suited for live sound processing. For example, it includes a real-time spectrum analyzer that can be used to visualize the frequency response of your audio signal.

This is invaluable for making precise EQ adjustments on the fly. Additionally, Gulfoss features a unique AutoGain feature that automatically adjusts the plugin’s gain setting in order to maintain a consistent output level.

This is extremely useful for avoiding clipping and keeping your audio signal clean and clear.

Gullfoss is a plugin that uses a computational auditory perception model to improve the sound quality of audio files. It is an ideal tool for amateur musicians and audio engineers who need to produce high-quality results on a consistent basis.

Gullfoss is a unique EQ plugin that makes the bulk of your decisions for you. It removes mud/resonance and adds clarity with a few simple controls. If you’re pursuing the perfect mix or master and you are already there, then this will definitely get you closer to your target.

I would highly recommend this product to anyone who is looking for an EQ that will take their mix or mastered track to the next level.

Overall, Gulfoss is an EQ plugin that is specifically designed for live sound applications and offers a number of unique features that make it well-suited for this purpose.

Rating: Five out Of Five Stars

Gullfoss is a unique EQ plugin that makes the bulk of your decisions for you. It removes mud/resonance and adds clarity with a few simple controls. If you’re pursuing the perfect mix or master and you are already almost there, then this will definitely get you closer to your target.

I’ve used it on guitars, drums, vocals, piano, and even an acoustic bass and every time it’s worked wonders. The low end becomes tighter, the mids become more focused, and the highs become more present without ever sounding harsh.

On top of that, it doesn’t add any unwanted coloration to your sound. I highly recommend this plugin to anyone looking to take their mixes/masters to the next level.

Gullfoss is a capable “automated” equalizer which is helpful for both an amateur who can not effort to hire a mix engineer for his first version of a mix.

For a professional, you get some unique results from this EQ that I would always take a look at to compare it to my manual approach with the different available EQs. I did use Gullfoss on some tracks, and when needed I added analog EQs for the analog vibe.

Soundtheory Gullfoss is an outstanding plugin for mixing and master engineers of all levels. As well as being incredibly effective, Gullfoss will assist you with your mixing and mastering decisions by providing you with an easy-to-use interface with a wealth of options for processing your audio.

In addition, Gullfoss comes with a comprehensive manual that covers all aspects of using the plugin, from installation to troubleshooting. Whether you’re a beginner or a seasoned pro, Soundtheory Gullfoss is an essential tool for anyone serious about audio production.
