20 Jul The basis for Ambiophonics is that placing speakers close enough to your ears that you get no significant crosstalk or audio “leakage” from the. Have you ever heard of ambiophonics? Basically it’s a different technology to reproduce the real ambience present in recordings and. The Ambiophonics method. ○ Ambiophonics is an hybrid method for creating a realistic spatial reproduction of staged music, starting from two-channel.

Directional speakers produce fewer room reflections than speakers with wide dispersion. I never got to like that position for regular listening.
Both the bass and upper treble “air” had an odd quality I can’t quite put my finger on. The presentation does not create an envelopment experience, where one is immersed in the original sound field, as the information is not present.
Room Correction Correction of speaker and room deficiencies has always been part of Ambiophonic theory. A purist should face the rear speakers when making the adjustments. Since both ears hear the same low bass—even in a stereo system—all low bass is mono.
For the first time in my life I am hearing music the way it was intended by the engineer and the musicians. So a miniambio is just a minidsp with the Ambiophonic plugin, plugged in. This combining of sound waves cause inaccuracies in the frequency response and smearing of the stereo field. Phantom images to one side of center are drawn in non-linear fashion toward one speaker or the other.
To summarize, it is possible to have realism without separation, via a combination of true hall ambience with a corrected front stage and this is the main thrust of the Ambiophonic method.
This works well in headphones or with interaural cancellation for one listener facing directly ahead and on the central axis between the loudspeakers. I have some six systems in different rooms and price ranges. The image with one amplifier is said to be more transparent, wider, deeper, narrower, shallower, more detailed, less ambient, or have more air than the other. The cancellation signal will be 2 dB smaller than needed to cancel the crosstalk.
That said, a lot of engineers tend to overuse it and the recordings loose their natural qualities. The rays should be at 5-degree intervals subtending a total of 30 degrees.
I am sure someone would have tried before and would like to know why Ambiophonics is avoided. Using recordings with the widest stage, or better yet a one-sided test signal see belowAttenuation and Delay settings have been optimized when stage width is just under degrees.
Ambiophonics – Wikipedia
Once you know the optimum settings, feel free to back off the settings to reduce the stage width to suit your taste or the recording. If ambiophobics do use six speakers for amviophonics, then when you play 2.
If Delay and Attenuation are correct for the speaker angle, you will have the longest sweet centerline coupled with the degree stage. If crosstalk cancellation is done first, the subsequent room correction ideally makes both speakers identical in amboophonics and timing when measured at the listening chair and thus there will be no problem.
But if one is lucky enough to have excellent speakers properly located in an excellent room, one might not hear an important difference from room correction. The large lab at Ambiophonics Institute houses the initial experimental no- compromise, high-end, 3D Ambiophonic system featuring front and dual rear full range SoundLab electrostatic Ambiodipoles, and electronics for the system’s 30 speaker channels.
Ambiophonics, you have to try it
ambioohonics I thought that for audiophile listening i already had my headphone rig, so why not. Firing ups some classical tracks off HD, strange sound. Ambiophonics is a method in the public domain that employs digital signal processing DSP and two loudspeakers directly ambiophoncis front of the listener in order to improve reproduction of abmiophonics and 5. Nothing to do with earphones or binaural recordings The real problem for Stereophile readers is that Atkinson has never heard an Ambiophonic system and so cannot do his job as a proper journalist.
As the frequency increases, instead of simple canceling, the comb-filtering effect predominates and ambiopgonics position of the images becomes frequency, and therefore program, dependent, changing so rapidly that no listener can sort out this hodgepodge of constantly shifting side images. I am really glad to hear that you believe the approach is ambiophoics because that is the biggest hurdle for audiophiles to try out new tech. In fact, a center speaker substantially degrades performance.
No need to buy other fancy gear, and if you setup it correctly it will probably be one of the biggest upgrades to the sound of your system, for free. Ralph Glasgal, glasgal ambiophonics. For example, multiplying and adding to the samples of an instrument or voice the acoustical impulse response of a hall as though the source had been recorded in that hall.
Reading more A lot more information can be found on the Ambio4you website at the Ambiophonics institute. Normally all tweaks and changes in settings will be heard only as slight changes in the width of the stage.
Delay and Attenuation must be set for the rear speakers and with the same criteria used for the front speakers. There is a lot of irony there, accusing a fellow scientist amibophonics facts of being “incorrect, self serving or misleading”, by countering with pure anecdote from those who “know”.
However, I cannot will not accommodate the physical separation structure in my listening room, so we talked about the electronic alternatives.
You are really making progress. Additional Reading Additional reading on these topics can be found on this web site: But a bit of a pain to use. Siimilarly, the level differences picked up by mics or panned and stored on disks or in files are similarly reduced during stereo reproduction so that a sound originally recorded at 90 degrees is now heard at 30 degrees.
Rate this topic 1 2 3 4 5. Similar matching panels can be used to reduce the reverberation time of the listening room to less than.
The development of ambiophonics is the work of several researchers and companies including Ralph Glasgal, founder of the Ambiophonic Institute; Dr. Sign in Already have an account? Here is greater detail of some points for non AES members who ambipohonics access the above paper and are too lazy to open links.
This stuff is nothing new. I am no longer being lied to by the speakers and the room I am in. Kal, maybe the time has come for you to cross the bridge, literally. A few measurements will accompany. Using the rear speakers on two-channel media insures that not all hall ambience comes unrealistically from the front. That as few as two channels should be more than adequate can be intuitively understood by simply stating that if we deliver the exact sound required to simulate a live performance at the entrance to each ear canal, then since we only have two ear canals, we should only need to generate two such sound fields.
Do not change the Delay setting.
