That's pretty good. Reminds me of QSound.
The original QSound had a different effect when played through Hi Fi speakers.
It was originally developed (as far as I'm aware), to enhance Classical Music recordings, but was never taken up by the major labels at that time.
It was tried out on a number of mainstream albums, three of which I own:- Madonna, "Immaculate Collection", Pink Floyd, "Pulse" and Roger Waters, "Amused to Death".
The last one I'm listening to at the moment.
Apparently, albums were recorded with some form of Phase Distortion, the result being that the soundstage seemed, or indeed was, much wider than the distance between your speakers.
And it worked. My speakers are about 9 feet apart, with another 3 feet or so to the side walls.
The various sound effects in "Amused to Death" extend right to the corners of the room. And you wouldn't get this effect by simply placing your speakers that far apart.
All you'd do is ruin the detail in your soundstage.
There's an interesting discussion HERE about QSound, and it appears that Floyds "The Final Cut" was recorded using "Holophonics" by Zuccarelli Labs. I wondered why that sounded so good without the QSound icon on the label.
Fascinating stuff, and a page full of info on all these methods of sound manipulation HERE:
