K-Stereo Ambience Processor vs. 'SHEPPi' Free Spatial Enhancer

'K-Stereo is a process that literally extracts the inherent ambience, space and depth in a recording and allows you to manipulate it.. I know this sounds implausible, but it can be done and there is a solid psychoacoustic (patent pending) basis for the principle. In mastering we often get recordings that are too small, and K-Stereo is one of the best cures for that disease because it does not affect the inherent mix, unlike typical M/S and other such 'widening' techniques. K-Stereo is totally natural and in addition, it improves the clarity and definition of the instruments and vocals as part of the psychoacoustics of the algorithm.'
(Bob Katz, Pro Audio Review, 8/2003)
..
'Widening of the stereo base is an attractive feature for stereo sets with closely spaced loudspeakers.. From this investigation it follows that the introduction of a small time delay in the crosstalk circuit shifts the regions with reinforcing localization cues in the direction of the listener, thus improving the localization of virtual sources in the widened stereo image.'
The Influence of Antiphase Crosstalk on the Localization Cues in Stereo Signals (Boers, 1983)
..
..I discovered about 10 years ago that a short delay (Haas) between 15-30ms, 1 channel inverted and perhaps a low pass filter can really widen things without destroying the mono compatibility or changing the mix. /minimonsta-vst-free.html. It just takes a TINY bit of the delay to really liven up things. Aside from that, a simple M-S matrix followed by some envelope manipulation and finally, an L-R matrix is all I use.'
(user wado1942 commenting on Gearslutz mastering board, 1/2009)
Let's be clear on something - I love Bob Katz. For those not familiar with his work as a mixer and mastering engineer of legend, Bob is one of a handful of guys (some others being Roger Nichols, The Lord-Alge brothers, George Massenburg, Rupert Neve, Alan Blumlein and Charles Dye) who have innovated, invented, educated and just plain helped set the standard for how modern recordings are made. It's just that I was re-reading Bob's book ('Mastering Audio: The Art and the Science, 2nd ed.') wondering about whether Bob's 'K' mixing system is all it's cracked up to be, when I stumbled across another term of his: 'K-Stereo'.
(Note to self - Is Bob planning to take over the best practices in the mastering world and label them all 'K' something-or-other? This reminds me of when Bob Metcalfe (of Ethernet and OSI networking model fame) was touring around the tech world trying to convince everyone that the old 7-layer model was passe, and we all needed to jump onboard his new Metcalfe 11-Layer Networking Model. In reality, the only thing passe about the 7-layer model was that it was in the public domain, and he was kicking himself for not having tied it up in some kind of intellectual-property wrapper. But I digress.)
In the audio world, we work from a fixed menu of ingredients beginning with Volume, Frequency and Time, working its way down into such specifics as delay, reverb, phase, modulation and distortion before hitting the general weirdness of psychoacoustic principles like masking, combination tones, Fletcher-Munson curves, HRTF plots and precedence effects. Many wonderful techniques considered 'trade secret' in their day (Flanging, anyone? ADT? Dither?) have since become standard practice and the guys who invented them (like Beatles' producer George Martin) have become legend.
K-Stereo was something different, though. Bob basically took a few mixing concepts already in use (these would include early reflections, ping pong delay, M/S processing and the precedence, or Haas effect), applied them all at once and took out a patent on it - while conveniently sidestepping everything that looked like prior art. The algorithm, which is a clever but fairly simple and straightforward psychoacoustic spatialization effect, has roots in at least one 1983 AES white paper besides theSpatializer patent (whose roots go back to 1982.) A more descriptive term for what Bob's doing might be the acronym 'SHEPPi', which stands for 'Stereo Haas Effect Ping Pong Inverter'. Yep, that's what it is. And it didn't take a patent to figure out - all it took were some basic signal processing techniques known (in patent legalese) 'to those skilled in the art.'
What SHEPPi describes is this. You set up a ping-pong delay with feedback of around 30mS, which is the sweet spot for the well-known Haas stereo widening effect. Then, in one of the crossfeed delay lines you put an inverter such that the artificial early reflections are bouncing around out of phase (exaggerating the wideness) and out of time with each other. Bob adds some extra control over this effect by determining whether the delay feedback ('Deep' switch) or single-channel crossfeed inverter ('Wide' switch) should be on or off. In addition, the K-Stereo process adds a couple of convenience touches easily simulated with other tools: an M/S matrix processor (also known as a 'shuffler') preceding the effect, and a post-effect EQ module for tailoring the synthetic reflections.
Open Ambience Project's SHEPPi Spatial Enhancer plugin (VST, Windows) does all of this. You can even use the plugin on an aux bus instead of the more typical track insert because SHEPPi gives you full control over the dry signal that's usually mixed in. (Try doing that with the Algorithmix plugin.)
How close is this implementation to the real thing? Extremely close. Listen and compare! Prior to now, I was reluctant about making the plugin public - but having since talked this over with a patent attorney (thanks, TS!) I've decided to go ahead with it. At some point I may end up making the source code available so that anyone can compile their own plugin without any IP concerns (source code is protected under the First Amendment, you see) but until then the most important part of the code, the core process, is outlined below. Click on Fig. 1 to read the original, orFig. 2 to see this effectmaker's implementation.
In practice, patent examiners only consider other patents and the books they have in their library for prior art, largely because the patent office has an elaborate classification system for inventions. This means that an increasing number of issued patents may be invalid, based upon prior art that was not brought to the examiner's attention. Once a patent is issued, it is very expensive to invalidate. (For more on this, seehttp://en.wikipedia.org/wiki/Public_domain)
Meanwhile, let it be said that I'm making no money off this - writing this plugin was merely a fun project to get a few licks in programming for the SynthMaker development environment, and I'm a curious guy.
(Note: SHEPPi is a 32-bit VST plugin until such time as as DSP Robotics decides to update their development environment. In the meantime, please investigate the amazingly clever (and cheap) JBridge 32-to-64 bit VST adapter for Windows)

'What a wonderful plugin you've made... I'd been figuring out the patent trying to do the same but it didn't work like the real k-stereo thing. I thank you very much for making it work well with very best regards'
- Arie Visser, www.studioavm.nl
' It's amazing how tweaking it just a little, the sound becomes fuller, cleaner, and more pleasing to listen to. I've tried it on my own recordings and commercial ones, everything sounds better.'

Personal Observations:
Now the double-blind testing starts. When I was working on an early version of this plugin (no EQ yet) you could flip the phase of its output and it would actually sum to null against the original, which is as good as it gets. That said, working around the bugs in pre-v1.1.7 versions of SynthMaker was an adventure in itself - but since everything seems good and stable, just trust your ears and enjoy. Users running Windows 2000 and earlier may need to install Microsoft's GDIPlus DLL, availablehere.
Apologies for the lack of a user manual, but if you've already read the guide to Algorithmix's demo plugin (hint hint) you're pretty much on top of things.

Best Ambient Vst
If you want to create digital music and need ambience vst, here are some ambience vst you can download for free and use in your music project.
While using vst instruments is a must in any digital music creation, using ambeience vst is the next step after music composition.
In mixing, reverb effects should be used as this effect gives nuance to your music like loop tools. you can defenitely beautify your loop tools nicely. Other vst effects can also support your project to make the output music sound better.
If you are accostumed to using reverb vst in your music tracks, then ambeience vst is nothing new. especially, those who always deal with reverb time. reverb vst plugins are available in internet and there are bunch of them to grab. However you need to be extra careful especially when it comes to performance of your computer. Reverb vst plugins offered for mac osx usually consume energy. unlike when used in other audio software like adobe auditin.
one of ambeience vst most musician use is magnus jonsson. this vst offers great control on reverb time while using only low cpu process or cpu usage. however, you can use this vst in major daw like fl studio, not in adobe audition.
The reverb effects offered by magnus jonsson can really enhance your vst instruments as this is one of most recommended vst effects. all virtual instruments need special touch with any kind of reverb vst plugins offering ambience reverb of vst plugins.
what about smart electronix? yes, that is one of the options.
no matter what os you use, whether it is mac os or windows, the key important thing is your creativity. Audio software like studio one should be one of your options. But, still you need vst plugs to work with mac osx.
Most digital music maker use mac os, not because it is expensive or reliable but because of its hardware performance. Cpu usage is the one that you should consider when using vst plugs.
adobe audition is a standard daw, or I may say for new bie when compared to fl studio and friends.
smart elextronix with its magnus can tell you how to correctly use ambience reverb correctly for your virtual instruments. don’t worry when using plugins from smart electronix, it is low cpu consumption.
