Algorithmix Chromium Series K-Stereo

Algorithmix, in conjunction with Bob Katz, has released a software incarnation of the Digital Domain K-Stereo processor.  The patented device can extract ambience and depth from existing recordings, allowing for post-mixdown adjustments.  The hardware version was reviewed in Tape Op #45. Check out your back issues or the manufacturer¹s website for more details on the process.

To my ears, the software sounds nearly identical to its hardware parent, but has the added benefit of multiple instances and a graphical user interface. According to design team, the plug in uses double precision 32-bit (64-bit float arithmetic) and the box uses 32-bit float.  Both run the same exact algorithm.  And while the original unit was ergonomically straightforward, having all of the controls available at once ­ plus the visual of the width and depth fields ‹ make this a wonderful incarnation of the original.

I tested the plug-in extensively in an attended session.  We all know that things tend to break when a client is present.  I was able to shift settings during play back, bypass and enable the plug in, and bring up numerous instances without any problems.  Like the original, I was able to use the K-Stereo to give a track that special sparkle that was missing or to bring out perceived space on a track that sounded narrower than the rest of the CD.  One word of caution: depending on the setting, the K-Stereo process can make your average level sound louder to your audience.  It may be necessary to adjust your gain stage in other areas of the chain.  Otherwise the K-Stereo processed track might jump out.

If you have ever had the pleasure of visiting a well-appointed wood shop, you'll encounter specialized tools that allow a master craftsman to handle special requests.  Mastering engineers are in a similar situation. Sometimes there are requirements that can¹t be fudged or simulated.  The proper tool is necessary.  The K-Stereo plug-in is such a tool.  This is not a process that you should use on every song, but when you need it, there is nothing that comes close to sounding like the K-Stereo.
