During the testing no crashes or noticeable bugs were observed; the plugin was very responsive and quite easy to use. A track with a lot of hi-hats had the top end of the transients cleaned up, so that the tick sound was more consistent. This gives us unique filters that have just the right trade-off between pre- and post-ringing so that the alterations happen in a way that is compatible with perception. The user can increase the perception of clarity, space and dimension of any input signal — with low latency 22ms , and no artifacts or phase destruction. Along with Managing Director David Pringle, Soundtheory has developed exciting new and unique methods for realtime audio processing. Both have their own amount percentage controls, and a third control called Bias determines how Gullfoss reacts in situations where it is less clear whether Recover or Tame would be most appropriate.
Bias: sometimes signal components can be borderline. I was very aware of that back then and did not find the signal processing methods related to perception and, more generally, time-frequency processing very satisfactory. Still, like most things audio, moderation is the key to success. Gullfoss buffers the audio even when in bypass. Positive values bias towards recovering, while negative values will give preference to taming.
Training a black-box neural network with examples of what it should be doing can be impressively successful and recent progress in deep learning certainly gave a few stunning examples for that. I still remember how that choir sounded in that church, and I felt like I could sense that imaging and energy with more truthfulness. Related: , by Rob Tavaglione, Pro Sound News, March 28, 2018 At this time, I was already deeply involved in researching auditory perception and we had been working on this particular model for many years, so it was obvious to try to use the model to see what pink noise does to it. I did get some good sounding tracks and also tried it on the mix bus and was surprised by the excellent quality. The Boost control, though expressed in dB, changes the frequency response to match what a listener would hear when the audio is louder or softer. A little too rude and crisp, the processing is then audible, but not loaded with artifacts like you might think.
There are 5 configurations that control how the plug-in interacts with the audio, plus a range of other controls to focus the processing. Gullfoss is an easy-to-use tool for everyone from the amateur musician to the professional mastering engineer, delivering exceptional results in a matter of seconds. The Helix Native we utilised had a preset consisting of all the elements of a typical guitar signal chain: compression, overdrive, power amplifier and cabinet. As this plugin should help all the not so experienced composer and mix engineer 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. Gullfoss on Rhythm Guitar Gullfoss on Solo Guitar The results were quite interesting. Well, I think now there is.
Like any technology it has its quirks — put many digital effects in sequence and some unnatural artefacts can emerge. If the algorithm is unsure whether the component should be tamed or recovered, it will use this control to bias its decision. The two main parameters are Recover and Tame. It comes with one computer-based authorisation plus a number of further online authorisations to allow you to put Gullfoss on multiple machines; online authorisations require the computer to be connected to the Internet during use, and only one of them can be used at any one time. In a world where competition for streaming real estate is fierce, a quick and effective workflow is essential.
Gullfoss is a very interesting plug-in that could be very useful for both beginners and as well as experienced engineers. You also have a Bias control that allows you to weight whether Gullfoss choses Recover or Tame in borderline cases, a Brighten control to make the overall sound brighter or darker and a Boost control that applies a smile curve or boosts the mids at negative values. Additionally, support has been added for higher sampling rates up to 192 kHz. The equalizer is capable of changing its frequency response more than 300 times per second and without introducing audible artifacts or degrading signal quality. If only there were a way to easily fix that beyond better rooms, better hearing and better skills.
Such an approach would not really work for us. Tavaglione: How can Gullfoss make so many adjustments so quickly without loss of phase cohesion or creating artifacts? These are used to track user interaction and detect potential problems. The user can increase the perception of clarity, space and dimension of any input signal — with low latency 22ms , and no artifacts or phase destruction. Linear phase introduces pre-ringing that is a lot more audible than post-ringing, because of temporal auditory masking, and the usual frequency response design methods are far too imprecise for our needs. The next control, Brighten, adjusts the overall tonality of the processed signal; as its name suggests, it can be used to lift the top end, but it can also be set to a negative value to reduce the highs if the source is already too bright. This could speed up the whole production process quite significantly if used wisely.
The methods usually involve listening tests, and produce tables listing the description of the perception of test subjects to certain sound stimulation. The pictures are static but the results are quite dynamic and change as the song progresses. The academic physics research I was doing was all about quantum theory, but apparently auditory perception was always in the back of my head. For more details and specific examples, please visit the official site of this plugin link below. Along with Managing Director David Pringle, Soundtheory has developed exciting new and unique methods for realtime audio processing. Auratones , that translatability is nonetheless always enhanced by Gullfoss. A gentle treatment certainly helps lift vocals out of a mix without making anything sound unnatural.
Apparently the designer makes extensive use of Gullfoss in his own projects to clean up mixdowns of multi-microphone recordings starting with equal settings of Tame and Recover, usually in the 20 to 50 percent range with Bias left set at zero. One of the most mysterious aspects of this plug-in is its name, apparently taken from an Icelandic waterfall. The meter for Bias shows whether Recover or Tame is currently active, while the Recover and Tame meters are combined in a split meter view, with Recover denoted by the top displayed bar and Tame by the bottom. Gullfoss by Soundtheory Review Gullfoss by Soundtheory has been for the last weeks on the review bench in Cubase. 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. I did need to relaunch Cubase, and all was fine.
Recover, Brighten and Boost can then be used to match the tonal balance of the output to the original. Tame seeks to find elements with too much prominence in your mix, correct their balances and subdue them. Recover increases the intensity of frequencies that Gullfoss has determined are being masked, whereas Tame reduces the intensity of the masking frequencies. Instead, we try to please your brain in a very fundamental way and leave aesthetic decisions to the user. A Windows version is scheduled to be released in 2018. The resulting computational perception model is therefore based on first principles with very few free parameters that depend on the actual physical realization of the human auditory system and can be estimated easily.
