How Does Holophonics™ Differ from Other Recording Techniques?

The objective of any other recording technique is to accurately reproduce in the listening environment (through headphones or loudspeakers) the same mechanical sound waves encountered by the microphone(s) in the recording session. The Holophonics™ recording technology does not use traditional microphones. Instead, a proprietary sound processing technique is used which captures the full spectrum of essential information traveling from the ear to the brain in the recording environment. During playback this information will reach the auditory cortex of the listener’s brain and recreate the same sensation as if one was listening to the original event. The process provides ‘natural’ listening rather than hearing mechanically-reproduced sounds.

Is Special Equipment Required for Listening or Playback?

Amazingly, Holophonics™ can be heard perfectly through nearly any stereo, set of headphones, or computer, whether inexpensive or of highest fidelity. For the first time, more complicated and expensive systems are not required for better sound (because in this case the sound is recreated in the listeners brain). It is, however, when using a speaker playback system, important to use proper speakers, in that most speakers on the market today are actually “three way”, and include separate woofer, mid-range, and tweeter speakers to handle the full range of sound frequencies. Separation of sound in this way within a single speaker cabinet results in the different harmonics of the sound reaching the ear at different times, distorting the information for the listener.

The ideal speaker for Holophonic™ listening is one where each speaker driver is placed in the same point, such as single-cone designs, or the phase-coherent, time-compensated coaxial speakers available from numerous manufacturers. It is important to use only two speaker units whenever listening to Holophonics™ regardless of the listening environment, and placed either directly on each side of the room or brought forward on each side to a position 45 degrees from center. Properly designed and positioned speakers will result in a solid image of sound or “audio hologram” in the room. The quality of tuner, amplifier, and player will naturally all have an effect on the final listening experience,  and digital systems and noise reduction technologies contribute to the accurate recreation of original spatial information for the listener, but even a $20 cassette tape player and set of headphones will produce remarkable Holophonics™ sounds.

How Does Holophonics™ Differ from Other So-Called ‘3D’ Sound Technologies?

The best analogy for explaining the nature of Holophonics™, is in the comparison of stereoscopic pictures  and a laser hologram. The stereo picture, taken by two discreet camera lenses separating the distance between the eyes, utilizes the parallax effect, or the ability of the human brain to integrate two different pictures and fuse them together to interpret the tri-dimensional topology of the subject. The hologram, however, utilizes the ability of the human eye to detect the actual tri-dimensional shape of the light hitting the retina (wave front). Therefore by reconstructing the original wave front coming from the subject, the eye recognizes its tri-dimensional topology just as it will do by viewing the subject of the hologram itself. Similar to the techniques used in stereo pictures, post production techniques like Q sound, SRS, Bendini, Roland etc. utilize stereo or binaural manipulation of micro phonic recordings in the final mix down.

Holophonics™ on the other hand is a recording technology that replaces the microphones at the beginning of the stereo chain, in the same way that laser beams and mirrors replace the perspective of the traditional camera in holography. The final effect of Holophonics™ is amazing “True To Life” and incredible 4D recordings (3 dimensions for location and one dimension for time). It is a challenge to effectively explain the exact effect that Holophonics™ has on the first-time listener. One approach is this, imagine that you are at your favorite concert or event and you relax and close your eyes for a while, now imagine that the next time you open your eyes you find yourself at home, and everything that you have just experienced was a Holophonics™ recording, if you can imagine that, then you know what Holophonics™ is all about.”
