Since my original post on Gullfoss (Intelligent EQ from Soundtheory) they released a higher resolution version for “mastering” a few months ago. Check out this video overview of Gullfoss Master (priced at $199).
For podcast production I don’t use Gullfoss that often but when I need to fix some really bad audio (which is all too common in podcasting) Gullfoss usually helps quite a bit.
Here’s a very helpful excerpt from this Sound on Sound article:
Gullfoss, the innovative ‘automatic EQ’ plug-in from Soundtheory, has just been made available in a Master edition, completing what is now a trilogy alongside Gullfoss Standard and Gullfoss Live.
We reviewed the original version of Gullfoss back in 2018, and were so impressed that we included it in that year’s Gear Of The Year round-up, as well as our recent 100 Plug-ins Every Engineer Should Try feature. It’s essentially a multiband dynamics processor, but while it presents the user with a familiar EQ-like interface and controls, under the hood it uses a mathematical model of human auditory perception to increase or decrease your audio’s apparent brightness, eliminate temporal masking, and even remove unpleasant resonances — all while sounding natural and “artifact-free”. Its inner workings (devised by mathematical physicist Andreas Tell) are far from intuitive, but in use we’ve found it to be perhaps the closest thing yet to a ‘make better’ plug-in, with SOS Executive Editor Paul White calling it “addictive”, and SOS Publisher Dave Lockwood lauding its ability to “tame resonances that you didn’t know were there until you hear them taken away, and somehow emphasize all the nicest bits of a sound without making it any louder.”
All three Gullfoss versions share the same processing, but have been subtly tweaked to better equip them for different roles. Gullfoss Standard is the most versatile, and trades off accuracy against CPU usage, while the new Gullfoss Master places higher demands on your computer’s resources but employs an “extended auditory model tuned for mastering”, and also presents the user with finer control resolution. The Live version of Gullfoss, meanwhile, applies less transient processing and can thus run at a lower latency of 2ms (compared with the other versions’ 20ms).
Happily, you don’t need to make the choice as to which version to buy: a single Gullfoss license authorizes all three versions, so you can pick and choose depending on your workflow. Existing users of Gullfoss will also be entitled to install the new Master edition.
The Gullfoss trilogy is available now, priced at $199
