This remarkable intelligent EQ can massively speed up the mixing process and help you get audibly better mixes. And it's on sale for Black Friday - 30% off on November 28 through December 3.  

Gullfoss is an EQ that constantly processes audio in real-time to maximize the listening experience and optimize audio for how the brain perceives sound. To achieve this, Soundtheory developed a computational model of audio perception to optimize the frequency balance of any audio signal. We were very impressed when we reviewed it recently, and you can read the review here.

And now some even better news, it's going to be on sale for Black Friday - 30% off on November 28 through December 3!! Click here to head to the web store.

Gullfoss Intelligent EQ

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.
