Yarlung Records files using SonoruS Holographic Imaging

Posted on

Thank you for your interest in SonoruS Holographic Imaging.[1] Some people say it feels like the sonic equivalent of virtual reality. Friends who have heard demonstrations of SonoruS Holographic Imaging have remarked on a realistic three-dimensional sound stage and have appreciated the natural presence of the musicians and their placement within the acoustics of the concert hall.[2]

If you have set up stereo speakers in your room correctly, this format can fill the room with musical information.  The free downloads on this page can help you decide if you like Holographic Imaging and if it works well in your stereo system.  If you don’t like the effect, or if the effect doesn’t work, please choose our regular stereo version of the same music.

Please note! Yarlung’s SonoruS Holographic Imaging files do not work on headphones.  Moreover, they only work for one person sitting in the center.  Two people listening side-by-side on a sofa will not hear the effect correctly.  You can sit one person in front of another, but not side by side.

Most importantly, Holographic Imaging only works if every component in the playback chain is phase coherent.  My “best” speakers, placed where I have them in my living room, do not image correctly enough to give me the full Holographic Image.  Please don’t be offended if your super-expensive system cannot accurately reproduce the holographic effect.  Not all premium audiophile systems are designed to incorporate this degree of phase representation.

Please download our Holographic Imaging test track first to determine if your system can accurately portray the signal circling around your listening position.[3]  Next, download our recording of Red-winged Blackbirds at a pond to experience 180 degrees of sound.  If you like this, try our samples of music, one in traditional stereo and one in SonoruS Stereo Holographic Imaging.  Please let us know your thoughts.

Footnotes

[1] SonoruS Holographic Imaging was created by Yarlung engineer Arian Jansen, using a proprietary matrix incorporating phase, timing and EQ information from two or more microphones to reproduce a three-dimensional listening experience from two speakers.  Jansen’s SonoruS Holographic Imaging processor works entirely in the analog domain, and fits neatly into a 2U studio rack, about the size of a CD player.

These Yarlung files are the first available Holographic Imaging music available as digital downloads.  There is a small but vibrant community of audiophiles well acquainted with Arian’s Holographic Imaging music on analog tape. This process is not proprietary to Yarlung Records and other labels are encouraged to explore releasing material using SonoruS technology.  Here is a brief description in PFO.  More information about SonoruS.

When you listen to a chamber music ensemble in regular stereo, for example, the music and hall ambiance come from within the field of your two speakers or maybe from slightly outside the speakers as well.  But in ideal circumstances, when you listen to a SonoruS Stereo Holographic Imaging recording of the same music, you will hear a wider sound stage, and you will hear (and almost feel) the concert hall around you as the musicians play for you on stage.

You will hear Yarlung’s Petteri Iivonen playing part of the Chaconne from Bach’s D Minor Partita in front of you, and you will hear test tones circling.  If your room and speakers are set up properly, they will begin directly your left, and move slowly to the right, crossing the center and then lingering again directly to your right.  The tones will then slither over to the left side and begin the circle again.  If the tones do this for you, great! Enjoy some of the new Holographic Imaging files we are making available.  If the tones do not perform as I describe them, I recommend the stereo or surround sound versions instead, which I hope you enjoy very much.
