Gullfoss is an easy-to-use tool for everyone, from the amateur musician to the professional mastering engineer.
Its intuitive user interface offers a set of basic parameters that can be adjusted to improve the clarity,
detail, spatiality, and balance of your mix or recording in seconds.
Take control with
Gullfoss, an intelligent equalizer that listens to your signal and decides how to prepare the sound so your brain extracts
the most information. Gullfoss’s real-time analysis uses Soundtheory, a computer model of auditory perception,
to understand which sound elements are competing for your attention. Gullfoss allows you to quickly and accurately resolve issues that
would otherwise be intractable or require significant time and expertise.
Gullfoss can even correct balance issues between different sound elements without accessing individual tracks.
Its internal auditory model allows Gullfoss to make objective decisions about perceived sound. As a result, mixes processed
with Gullfoss tend to be more consistent across different listening situations.
Gullfoss’s new patented equalizer technology delivers unrivaled sound quality. The equalizer is capable of changing
its frequency response over 300 times per second without creating distortion or degrading the signal.
Combined with a highly advanced computational auditory perception model developed by Soundtheory, Gullfoss is the first
and only product of its kind.
Three versions of Gullfoss are available to all users:
