Edgar Choueiri is a professor of applied physics at Princeton University, where he is the director of the Engineering Physics Program and the chief scientist of the university's laboratory for advanced spacecraft propulsion (the Electric Propulsion and Plasma Dynamics Lab). Right, he's a rocket scientist, but he's also an audiophile.
Professor Choueiri's Pure Stereo system is a "Revolutionary Technology for Audiophile-Grade 3D Audio." I was treated to a demonstration in Professor Choueiri's lab in Princeton, so I can tell you it really works. The professor played a variety of commercial classical and rock recordings, including Led Zeppelin, over a pair of closely spaced speakers (see photo). The sound spread to the full width of the room, and projected sound forward. He also played recordings he made, including a "haircut" with the sound of "scissors" snipping away all around my head. Professor Choueiri's 3D claim is no hype; Pure Stereo sounds amazing.
The technology can be used with any stereo system, and can operate in any resolution, including high, 192-kHz sampling rates, at 32-bit resolution. Pure Stereo is also compatible with analog sources like turntables and FM radios. Professor Choueiri doesn't equate Pure Stereo (two speakers only) with surround-sound systems that produce envelopment from multichannel music or movie soundtracks from five or more speakers. Pure Stereo's goal is to create more accurate spatial reproduction from two-channel recordings.… Read more
