Ambio4YOU, Immersive audio in your living room

Looking for a unique listening experience? Welcome to the world of Ambio4YOU and our flexible Ambiophonics Digital Signal Processors. In Hifi, Movies, gaming, 3D, or car audio systems, Ambio4YOU's platform are about to rock your expectations of how music or movie sound should really sound.

Ambiophonics is a method of audio reproduction based on Digital Signal Processing (DSP) and a specific speaker arrangement. Capable of reproducing audio with a listening field of 180 or even 360 degrees, it is a trully immersive and realistic experience. Once you have heard Ambiophonic, you will realize the limitations of the familiar stereophonic (2.0) and surround sound (5.1/7.1 setups). Initially implemented in 1986, Ambiophonics research is based on the subjective human perception of sound (psychoacoustics). Or in other words, how your brain interprets audio waves. The following sections summarize the work of years of research, backed by the Ambiophonics Institute among others.

The best sound I have ever heard is from binaural loudspeaker systems like Wavefield Synthesis, Ambisonics, earlier 3D Imax, and Ambiophonics. Basically the stereo loudspeaker triangle just produces a sonic illusion like an optical illusion. It is a neat trick but cannot mimic normal everyday binaural hearing and localization. Stereo is a nice 80 year old hobby and artform so that is fine.

Kalman Rubinson reviews, in Stereophile, a DSP equalizer product from miniDSP. This is the same Hong Kong company, dsp4you and ambio4you that makes the miniambio component. Why Stereophile does not review their real high-end audio component rather than their professional test equipment is a mystery to me. But the DSP product got a great review so I guess readers of Stereophile now have permission to try the miniambio box as well, since it is coming from a certified high-end supplier. It is 96/24 and analog in and out so it is in the vinyl world.

The miniambio box converts 2.0 files like LPs or CDs to binaural loudspeaker ones in realtime so you can avoid the stereo sonic illusion trap.

Two papers from NYU (one for the AES convention in Berlin this Spring and the other a master’s degree thesis) also certify that the program used in the miniambio is absolutely flat, indeed much flatter than stereo or SRS when measured at the ears rather than as Stereophile does with a test mic close to one speaker. You have to see these response curves to believe how bad the normal stereo loudspeaker triangle frequency response actually is and how easy it is to have it truly flat again at the ears where it counts. Such attributes as sound quality, immersion, depth, clarity, presence, stage width, etc. were evaluated by 44 listeners and discussed in both papers. Plain antique stereo did not fare very well in comparison to Ambio. But this is like having a panel compare black and white photographs to color ones of the same subjects, same resolutions, focus, aspect ratio, etc. Black and white will usually still have one or two adherents out of 50 viewers.
You have only to listen to a demo of Wavefield Synthesis, Ambisonics, Princeton's BACCH, Panambiophonics or Ambiophonics to know that other systems like 2.0, 5.1, or 22.4 definitely do not capture the magic of a live performance. The argument I normally hear at conventions is that stereo and 5.1 are not intended for anyone who wants live sound. These multi mono methods they say are better than live sound especially for movie,s etc. Basically, any system that relies on the stereophonic sonic illusion for localization is doomed to sound unrealistic to any normal brain no matter the number of speakers and how many tweaks are involved.

The main damage that using speakers at 60 degrees to reproduce 2.0 files is in the area of localization cues such as ITD, ILD and Pinna function. Otherwise, the use of stereo speakers at sixty degrees does not affect noise, distortion, masking of anything, etc. anymore than speakers at other angles or a binaural loudspeaker system There is also a frequency response change with using stereo speakers at 60 degrees due to combing starting at about 1500 Hz and a doubling of low bass for any sounds that are common to both speakers that Stereophile will never tell you about.
