NEUTRAL AUDIO TECHNOLOGES have the first deintermodulators ever!

PROMISES TO ENHANCE ANY SOUND SYSTEM BY ADDING IT

These are the first of their kind, attenuating intermodulation, which is interference of electronical interacions and brining richness to music, weather live or not, and clarity that will not be forgotten!

D.R.E.i- dynamic reduction of electronic interactions

With their X-DREi Pro model, widly used by artists such as Sir Tom Jones, Seal, Allen Parsons Project, Jamie Cullum, Rihanna, RHCP, etc. used in-ears, FOH and studios, technicians are using this technology more and more. Neutral Audio are now offering the DREi Micro, a smaller model, enhancing any sound system it is inserted into, live or domestic bringing a fuller bass and clearer top end, clarity and richness.

the DREi Micro Model is the best seller at the moment due to its affordable price.

All of NEUTRAL AUDIO de-intermodulators are now avalible to everyone

I've been on your site., and found the text below.
You aren't connected to a Mr. R Andrews are you?

From your website..... (About your technology)

· It readjusts and corrects errors produced by the electronics due to their tolerance errors and that can add up.
· Small musical details that may be hidden by the interactions of electric circuits, appear with unusual force and cadence.
· The timbres and nuances of the voices and instruments are more present and harmonious.
· Clarifies orchestral and choral masses, affected by digital circuits used in recording and playback and which are masked by other instruments.
· Absolute control over the total signal power to be amplified that is always directed to the filters and speakers, and preventing energy to be taken from other frequencies.

I suspect some of the strange claims and use of language are due to this being a Spanish company, and English may well not be a first language.

But I looked at the website too and also struggled to form a good understanding of what the technology is supposed to do... clearly a primary function is heavy filtering at both ends of the audio bandwidth, but the blurb reads like the usual hi-fi snake oil and is meaningless gibberish. It's a shame, because I suspect this might actually be something quite clever and useful...

As to DREi...

"You can watch as triangular and square waves are reinterpreted to be more like sine waves and avoid problems with sound reproduction."

So it's a severe low-pass filter??

Yea the bandlimitted squarewave is also pretty nice!

Kind of a bit useless - people don't SEE sounds, they listen to them and you don't have an audio track so that the difference (or DREi 'enhancement') can be heard.

What was more uncomfortable for me was the video showing DREi on/off with triangle and square waves HERE (again, no audio). The triangle is turned into a slightly asymmetric sine wave and the square wave becomes an odd, spiky pulse that's quite boosted in level.

I have a modular analogue synth - I would have to quite heavily filter the triangle wave to get a sine and use the Clipper and/or Rectifiers module or a fairly resonant bandpass filter to get that spiky square wave. Which is fine in that context for the creation of sounds for making electronic music. Not sure I'd want my audio mixes so radically altered.

But before/after audio examples would be more effective than oscilloscope traces.

--------------------

It's not weird, it's just showing the effects of band-pass filtering on simple waveforms.

If you remove or reduce some of the higher harmonics (integration) from a triangle wave you end up with something that looks a lot more like a sine wave -- the asymmetry and bent sine wave shape is due to the remaining harmonics and their relative phase relationships.

And if you differentiate a square wave (high-pass filter) you lose the flat tops and bottoms and get the slopes that change in direction when the polarity switches. How spiky it looks depends on the filter time constant relatice to the fundamental frequency.



So these fabulously untechnical wobbly 'scope videos imply that the DREI technology is little more than a band-pass filtering system. How did we ever cope without that before... oh wait...

I don't know whether these pointless and meaningless videos are being posted by a a completely non-technical marketing bod who doesn't realise how silly he is making the company look, or whether this is a deliberate attempt to blind idiots with non-science like women's face-cream adverts! If the latter, then he's come to the wrong place... We're not worth it!

As I said earlier, it's a great shame because the endorsements (some of which seem to be from from credible people) suggest there is something interesting and worthwhile about this processing in some way.

Could be worse - could be the other way round.


This is like watching the Christine Hamilton and her husband Whats-His-Name on 'Have I Got News For You'.

Actually on reflection I'm sure lots of people would be glad to pay quite a lot for a neutral deintermodulator. Presumably the more neutral it gets the less apparent it sounds and the more expensive it becomes until you're paying top dollar for premium product which sounds -almost- as if it's doing absolutely nothing.

But... What does it DO?

Perhaps if you were to provide Hugh and the guys a review sample they could review it and tell us.

What is DREi?

DREi reinterprets the waveforms:

A speaker is fully efficient when it comes to reproducing sinusoidal waveforms. DREi reinterprets the signals to be as similar to sinusoidal as possible, limiting the amplification of waveforms unsuitable for the speakers. Passive filters in the speakers also tend to respond worse with square or triangular signals, especially the capacitors and coils. At no instant any information is lost, only redefined, and so the total final energy is the same as the original.

DREi is a DeIntermodulator:

Harmonic Distortion Neutralizer. Daily engineers and technicians work to reduce the inevitable intermodulation that occurs in the electrical signal that flows through the electronic components and impairing the purity, the three-dimensionality and the finished musical quality. They also use various tools to minimize the intermodulation of the nearest frequencies. DREi attenuates both modes of intermodulation, becoming a powerful tool for optimum sound.


DREi adjust the soundstage:

Using a new topology of amplification, DREi dynamically controls multiple buffers or preamps for a stereophonic signal. This enables the user to adjust the end soundstage by controlling these buffers and obtaining the best response in conjunction of the amplification, speakers and listening position. It is not an equalizer, and does not produce audio artifacts. The frequency response is affected depending on the chosen position to align the associated system. The user can disable these sound stage modes, but the DREi process will always be run at 100%.

· Strong, powerful and detailed bass
· Very present and extremely clear treble and midrange
· Clearly defined soundscape and background
· Clear air and audible reverb tails
· Eases mixes in the professional sector
· Better sound diffusion in live concerts
· Eases tone in the in-ears for artists
· And more ...

· Enhances the overall sound quality of the system of which it is installed. More efficiency and better performance.

· Corrects errors produced by the electronics due to tolerances that can add up.

· Small musical details that may be hidden by the interactions of electric circuits appear with unusual force and cadence.

· The timbres and nuances of the voices and instruments are more present and harmonious.

· Clarifies orchestral and choral masses, affected by digital circuits used in recording and playback and which are masked by the other instruments.

· Controls the total energy of the signal to be amplified preventing energy being taken by other frequencies.

The music flows smoothly, neutrally and with crystalline transparency
AS A RESULT A MORE EFFICIENT SYSTEM.

· You get more natural clean and accurate sounds
· The dynamics are increased
· Real and defined voices with full integrity
· Greater channel separation
· High dimensionality and distinction of sound levels and layers
· Increased openness
· Minimizes acoustical problems in rooms
· Increases the sound pressure with the same system
Test a DeIntermodulator in a real situation. You can personally check that does what we say.

Mitigate the harmful INTERMODULATION that occurs between two or more signals with different frequencies (or instruments). They occur in all the elements that make up an audio playback system and impairs the purity of the original musical signal.

Please provide good quality audio files so we can see/hear for ourselves the benefits of your work.

Oh dear...

... this seems to be on a par with the 'advice' I was given way back in the 70s not to buy a mixer with more than four channels as the electronics couldn't cope with blending too many signals together...

This sounds like a great device to review for the April issue..

One hardly knows where to start with rubbish like this, as it comes very close to fraud.

I wonder about people like this and wonder if some of them sometimes believe what they are saying. All this nutter has got is a simple filter (as Hugh pints out). This is O-Level stuff, when we discovered the magic workings of a capacitor and got to see the physics teacher fiddle about with an oscilloscope and hear the results through a speaker.

But it does make for fun reading!

But some people SO want to believe this sort of thing...

As I've said previously, I think the product itself probably does do something useful -- and the endorsees and reviews appear to support that notion. What we have here is an excess of marketing enthusiasm with an almost complete lack of technical foundation... but it's hardly the first time, is it? Lots of companies fall foul of the same kind of nonsense.

I suggest we all reserve judgement until we can arrange first hand experience of this product.
