Soundtheory has updated Gullfoss to version 1.9.0. They say:
Starting with version 1.9.0, Gullfoss now comes in two flavors. The established version of Gullfoss for mixing and mastering in the studio is accompanied by Gullfoss Live, which is optimized for low-latency situations like tracking and live mixing. At a latency of less than 2 milliseconds, compared to the approximately 20 milliseconds for the regular version, Gullfoss Live delivers pristine sound quality and all the same features. The sound gains a little more character as the low-latency algorithm treats transients differently. This difference also makes Gullfoss Live an alternative for mixing and mastering music styles with very pronounced transients.
With the new release, Gullfoss gains support for sidechain processing to enable stem mastering, content-driven ducking and creative sound-design. The EQ display gain scale can now be changed so that even the most subtle movements can be observed.
The new equalizer engine improves the sound quality of Gullfoss and a new algorithm delivers a smoother high-end and a warmer low-end designed to satisfy the most critical listeners. At the same time the CPU performance is improved at very high sampling rates.
Price: $199 - Gullfoss 1.9.0 including Gullfoss Live is a free update for all existing users. A free 14 day trial can be downloaded from soundtheory.com/support
