😎 World's First Fourier Transform Speaker: Audio Revolutionized?

[@TheBlindAudiophile]

Manufacturer Response: The name of our speaker and the use of the term "Fourier Series" in our video has led to some reasonable criticism in light of the information available. While we use the Fourier Transform in our Fir filters many crossovers, beyond that we use a different algorithm to extract the signals fundamental and harmonic series, which I stated in the video gets summed as the drivers produce their assigned sinusoids. As an analogy both terms fit. We extract the fundamental and its harmonics from a signal as does the Fourier Transform, but our algorithm is far more practical for reproducing music recordings with loudspeakers. We sum the sinusoids analogous to the Inverse Fourier Transform as the sine waves leave drivers. The effectiveness of our new approach in sound reproduction was noted by numerous individuals at the show who stated clearly we sounded not only unique but were the best sound at the show in spite of its chaotic and work in progress look. , We will reconsider our explanations in the future to both avoid this confusion and protect our intellectual property. We will be in LA in June for the show with a commercial product. We will have a room for listening and another to demonstrate its unique ability to stay in phase with the input and whose output maps over the input perfectly. All criticism is welcome but we especially look forward to all responses from individuals who have heard them. We know this new paradigm in sound reproduction is so radical many are convinced that it can’t work and nothing but nonsense could claim it does. Fred Slaven Fourier Transform Speakers.

Having a master’s degree in electrical engineering with a specialty in signal processing, I can say that the technical explanation provided here was mostly mixed-up gibberish.

[@FredSlaven]

While we use the Fourier Transform and its inverse for our FIR filters only, we apparently failed to grasp that using the term Fourier Series or Fourier Transform as an analogy to our process of pulling out the underlying sine waves making up the signal, would be taken so literally. The Fourier Theorem led to a realization that when it comes to sound, it's "turtles (sine waves) all the way down". That led to our explorations, experiments and eventually our speaker. We don't use the Fourier Transform to break down the signal into its harmonic series, true, but an alternative that is far less demanding on compute and still uncovers the sine waves needed so our drivers can operate in a linear manner. The resulting sine waves extracted and their summation is so accurate we can actually map our speakers output onto the input signal. We are the only speaker that can do so. No doubt your experience and response should be taken seriously and we will reconsider our interview in that light and see how we can explain the speakers without handing out patent process in the process.

[@rupertchappelle5303]

I find your lack of faith in gibberish to be disturbing and impolite to the gibbering community.

[@exponentmantissa5598]

Drivers do not have to stop instantly and change phase which he claimed. That would be a step function which never occurs in audio and is impossible for an amplifier to reproduce as it would require infinite slew rate. He also claimed his drivers are all in phase. They are not because there is a distance between them. In addition he is going to get a ton of diffraction and reflection off the speaker array. He has made a classic audio mistake. He claims a problem exists that doesnt and then does a ton of design work and cost to fix something that it is a non issue.

[@TheBlindAudiophile]

As for the comment about direction changes we were not talking pico seconds but fast enough to stay in phase with the input signal. We are the first to so so replicating the input signal with our speakers output. As the designer we were concerned about diffraction but what the hell, let’s see what the effect would be. It was moot. We were amazed at how little effect it had. As for phase from the difference in the drivers vertical position, When a group a driver produces a square wave they are aligned on both axis’s. we use dsp delay to accomplish this.eNot quite that simple but close. We will be in LA in june w a finished product Drop by .. It’s all Bs, including ours until one hears the speaker. Show response was overwhelming positive. Most recognizing a new standard for Hi End.

[@mysock351C]

@@TheBlindAudiophile This is a fundamental misunderstanding (for one reason or another) of what the Fourier transform is, and why its needed. Systems that can only assume discrete states cannot process continuously varying signals such as analog audio. The transistor in the DSP chip is on, the transistor in the DSP chip is off. The neuron in your brain fires, the neuron in your brain stops firing. They have no in-between states. This is where the Fourier transform comes in. It allows a continuously varying signal to be decomposed into its spectral content vs. time which is something such state-based systems can process. Speaker, however, can assume any position they want to by design. As such, speakers are ONLY made to reproduce continuously varying analog signals, and don't do well with anything else. Also there is the massive issue of dispersion patterns and interference, which is why modern speakers require computer aided simulation and design to actually get them to have good directivity, which is a must. Using speakers made from the entire Parts-Express catalog each playing only one very narrow range of frequencies is like trying to paint the Sistine Chapel with a hand grenade and a bucket of paint. Its at best wildly misguided

[@mysock351C]

@@TheBlindAudiophile Also insofar as audio is concerned, the resulting "harmonics" of each of the sine components are actually harmonic distortion. We DONT want those as they shouldn't be there! Its an intriguing "what-if" idea. We've all had such moments of whimsy staring at measurement equipment or mathematic equations. 😀 But to actually attempt this is fundamentally flawed in very profound ways.

@@TheBlindAudiophile What happens to imaging when you essentially break apart an instrument into different locations for different frequencies?

[@johnlehew8192]

It is well known that Fourier is used to split signals into different frequency bands. It is mathematical processing and unlike physical capacitors, inductors, and resistors it will maintain phase in the signals whereas physical electronics distort phase. It converts a time based signal into a frequency signal that can be easily filtered by removing everything outside of 200 hz and 300 hz then converted back to the time domain to play that part of the signal. Based on the explanations in this video, I don’t believe anything special is here. I think this system is simply an active crossover driving 15 speakers. It is missing a good engineering explanation as to why it works, there is an explanation but it doesn’t make sense plus the designer mentions he recently learned about Fourier. It is a very complex subject and was first applied to phone signals when they first came out to reduce noise and boost signals. I took a semester on nothing but Fourier in college and this is a hard subject to learn on your own. I encourage the designer to prove me wrong and explain how this is not an active crossover and provide better explanations of how it works. I’m big on innovation and wish him the best however this isn’t passing the smell test for me.

[@Mikexception]

I share objections. This effort is concentrated on only one factor - phase shifts in crossovers. It is explananable only if author heard about that problem but did not experience other rest. Even if it works ( I have not enough knowlegdge about FFT except that it has to be sampled, conveted to digital form and after analyzed, it takes time and how about many uch operorations for each speaker in instance I have no idea) He did like perfect suspension for one of four wheels in car. It is important to have all good cooperating together. resulting in smooth ride of whole car in compare to one best suspension and other suspensions as usual. There are lot of phase shifts in audio and true art in audio design is to make them compensate each other, not to beat any of them to zero - it is better to controll them for best result. .

[@TheBlindAudiophile]

It was just a year of so ago I saw using the Fourier Theorem and it derivative equations as a model in speaker design. You are not incorrect in seeing it as a active speaker with 19 crossovers actually. But that's like saying a diesel locomotive is nothing more than a diesel engine coupled with an electric motor. That would also be a true statement but completely misses or ignores the point of using the diesel engine to provide current from a generator and the electric motor for its strengths the diesel engine lacks.

[@exponentmantissa5598]

Imaging would be destroyed by this as now your musical instruments come from multiple locations. In addition any filters introduce phase shift near the crossover points. This is unavoidable. All too often I see people create an audio reproduction problem that doesnt exist and then spend a ton of money to fix something that was not broken to begin with. A perfect example is expensive cables like USB.

[@Nonsense62365]

ROTHLMAO!

[@johnstone7697]

The drivers are all mounted in free air and facing upward. But because of the close stacking there's a tremendous amount of diffraction created both off the driver basket above and the one below. Regardless of the DSP involved, these drivers are operating in a very sub-optimal environment where in phase and out of phase energy (front and back of cone) are simultaneously being radiated into the listening space. Lots of signal cancellation results, especially on the listening axis. I assume the goal is to make it omni directional, but this design puts tremendous demands on the drivers to produce any substantial amount of energy at the listening position.

[@TheBlindAudiophile]

As the designer we too were concerned about diffraction but what the hell, let’s see what the effect would be. It was moot. We were amazed at how little effect it had. As for phase from the difference in the drivers vertical position, when a group a drivers produces a square wave they are aligned on both axis’s. we use dsp delay to accomplish this.

“Nature adds them up free of charge.” Yes. It’s called a SPEAKER. We can even do really nifty things like using coaxial drivers and waveguides to ensure that the SPEAKER delivers a nice uniform sound and symmetrical “time aligned” dispersion pattern across the audio spectrum.

[@danielgeiger7739]

This looks to me rather like around 17-way speaker that is 17-way amped. I see nothing that corresponds to a proper Fourier Transformation, where true sine waves interact with constructive and destructive interference to produce a derivative. That was quite clear when he talked about one speaker emitting sound from three piano keys, which is a range. A true sine wave has no range by definition. A test would be to only amp one of those 17 speakers and see whether it truly produces a single tone, or whether one speaker shows some variation in pitch. my 2c as a wet scientist.

[@TheBlindAudiophile]

There is a lot of misunderstanding here. I’ll take the hit for that and see if I can avoid this confusion when we introduce our finished product next June. My choice of words will have to be better.

[@TheBlindAudiophile]

The next show will feature individual amp outputs show the musical signal been created out of a series of sine waves. It is in fact a 21 way speaker system. So you are correct essentially. But that is like saying a diesel locomotive is nothing more than a diesel engine combined with a electric motor. This would also be true but completely missis the point of combining the two as was done with this speaker design.

For those unfamiliar with the word "fourier", I'll put more details in the description, but in essence, the Fourier theorem provides a powerful tool for understanding and analyzing complex waveforms by breaking them down into their simpler components.

[@immovableobjectify]

True Fourier analysis and synthesis (involving reconstruction from pure sine waves) would require an unreasonably large number of separate channels and drivers, Here he even says that each driver covers a range of about 3 notes (in I assume the Western 12-tone scale.) No pure sine waves are involved. It seems like this is just an extreme multi-way speaker with a digital crossover, and separate amps for each driver. Maybe if and when he is ready to sell a product, it will have some advantages over typical 3, 4, 5, and 6-way designs, but I have my doubts.

[@Thomas..Anderson]

@@immovableobjectify Add to that it has some sort of a vertical dipole configuration, distances between drivers way above wavelengths, diffraction from all those drivers. No wonder he cannot pin point the source of the sound.

I see some weak points - first to make it work we need to digitalize , analyze and following bring back to analog. It is not kept all the way in analog. It callls for decisions about bit rates, types od conversion and quality of all that. Simplicity up to me is best. . Then assuring exact timing of all processes - time shifts would unfortunatety appear instead of those beaten. Is the result justifying that effort it is not proven for me - I cant say it is sound which I would even accept for me . At end every speaker even every part of it's membrane which is not in exact distance from ear (and they are mounted horizontaly! ) provides it's own unique phase shifts in own reproduced range and it is capable to nivelate effort. At best it is beatingto zero pure unique crossover phase shifts. But phase distortions are not adding and not worsening (like say THD or timbre distortions) - they do not add lineary - they go up and after getting maximum they go down back to zero and go opposite with maximums at +180 or -180 deg. cancelling one of reasons may in some cases result in increase of total shift. Like using not tasty ingerdients we make best creamy cake - better not forget about any Author is convinced that headphone sound may be treated as perfect reception but does he notice that when the ear shells are pressed by headphones to head and change their form it completly changes listening perception making it no comparable to free listening?

Thanks, and you are correct that we had problems with the bass. We got feedback on the first day that we had both too much, and too little bass, which was perplexing.

[@FredSlaven]

Actually only a 1/4 octave. When the dynamics of music are in play, only a single sine wave is being reproduced and when there are more, say D5 and D#5, within any range, the linear functions of a sine wave function is retained varying in amplitude only, never having to produce a non-linear signal.

[@adrianfisher9641]

Oh dear! Alchemists at work. I sometimes wonder if these sorcerers have actually heard what accuracy is. There have been so many of these attempts to improve loudspeaker sound and they all fail.

"According to the Fourier theorem, a steady-state wave is composed of.." exactly "In simpler terms, it means that any ..." "steady-state wave..." Fourier Transforms convert time based information into frequency based. This works on "steady-state wave[s]". But it takes a period of time before the transform can recognize the repetitive frequencies involved. Music is transients. Not a "steady-state wave".

[@TheBlindAudiophile]

The Fourier Transform is a model. We went another route to uncover another symmetry, or a distinction without a difference other than speed of computation.

[@Mikexception]

You hit point - when I used FFT some 10 years ago, no more I had to record digital sample of sound which was "frozen" for analysis

[@flex-cx9bi]

Understood... Another way to decribe music would be a infinitely and instantly variable "steady-state wave". (aka everything recorded at the same time regardless of it's a sine wave or the complex harmonics of a cymbal). There is now way you can bandwidth limit that into 17 different parts and replay it with 17 different drivers and expect it to be better that a normal loudspeaker that is phase and time coherent. Just unnecessary complex.

[@cbts0029]

I think it is a dipol design without a baffle. Without a baffle it cannot play very low, because of a acoustic short circuit. It radiates more to the ground and the ceiling in a double cardioid form

[@flex-cx9bi]

Hence the bass boxes beside the stack of drivers. They play bass. Can't cheat physics, right? 🙂

[@michaelkanna9188]

A dipole would be a Open baffle speaker. This speaker is baffle-less, or omni-directional. All sub drivers are going to roll off at about 60, and eq-ing can't really fix physics. So there is a closed box sub to provide the very bottom. The other solutions is to "compress" the bass wave

Quad Electrostatic speakers are phase-coherent. So are Magneplanars. They are much simpler than this setup.

[@flex-cx9bi]

Sure do... Next step for the designers enlightment would be for him to discover that he needs a full wavelength between each driver to have them play in phase with each other. Each pair of drivers need a different distance between them. Can't see that...

[@FredSlaven]

@@flex-cx9bi disagree. The sound they put out would refute your understating and we compensate for vertical delay between drivers with dsp.. As would the fact our speaker output actually maps on the input signal. We are the first speaker to do so and will the first to demonstrate as much at our next show. The Seattle show being our first it was just too much to manage not to mention reserving another room to demonstrate this without first knowing others could hear what we heard. This show was just a confirmation bias test so other could hear our proof of concept. The show was a huge success so we will be in LA next year to show our prototype and demonstrate its unique output comparing the input signal to our speaker output.

[@stevemccormack5483]

A truly fascinating concept, and they seem to have pulled it together into a speaker that sounds quite good - very impressive! Rather complex to build, and I have to assume that with 40+ amplifier channels required, they are using most or all Class D amps. I am curious about their front-end...did they have to create the Fourier deconstruction algorithm, or is it available commercially? Apparently they can choose the number of output channels they prefer and derive the FFT outputs in near real-time - pretty amazing! Follow-up on this one, please.

As the designer I too found the results of actual experiments unexpected. Tests to see how such effects as diffraction, phase cancellations etc were negligible. It's not a perfect product yet but damn, it sound better than anything else at the show. That shouldn't mean much to you as I am the creator but I can tell you my reference in all cases was a pair of very expensive planar headphones, and my standard is a speaker that doesn't sound like a speaker. We did that IMO. Test results were unique in that the speakers can actually stay in phase with the input signal and duplicate it on it output. Both unique in the industry. We will demo such tests at the LA show next June. It was just to much to take on since the Seattle show was out first and we still did not know if others would hear what we heard.

There is no such things as a Fourier Transform loudspeaker. The Fourier Transform is mathematical technique. What you are seemingly claiming is that the sound pressure measured in-room (or anechoic?) follows perfectly the input voltage signal. In that case, the phase response has to be linear, and the magnitude response flat. This can be achieved via DSP, as you seemingly also use. Let us see the frequency response measurements (magnitude and phase), instead of small time domain signal section of a song. Don't make it out as you have discovered something new that is not taught to engineering students on the daily.

This was a proof of concept production. Price and complexity will drop dramatically once the minimal demands on drivers, amps and dsp units are taken advantage of and combined into a size of your average hi output A/B amp.

I’m confused

[@EskWIRED]

IMO, simpler is usually better.

[@TheBlindAudiophile]

On the level of physics, it’s far simpler with a fraction of the demands producing a complex signal requires.

Brilliant! Reminds me of the famous explanation of the Turbo Encabulator: kzbin.info/www/bejne/d5SaeGquhKxld8ksi=M0-np5PGhVG5MqO-

[@armoredsaint6639]

But.....does it sound good?

[@bartvanransbeeck1341]

Sounds very clear uncoloured

[@flex-cx9bi]

Yes, it's a boxless design so pretty much free of energy storage or resonances. Pretty much a open baffle without the baffle. The concept is simply a 17 driver normal loudspeaker. As long as one driver plays in it's linear area, which can extend for many octaves there is no need to divide it into several drivers with complex equalizing. Within the drivers linear area phase and amplitude is pretty much linear, and the designer of this loudspeaker seems to have forgotten that. Funny experiment, but with no benefit to a normal loudspeaker designed properly. So commercial potential is absolutely zero. Some might believe the sweet talk and get tricked to belive that this is something revolutional. It's not.

When will it ever be practical?

IMO not that far from the ESS Transars.

I prefer analogue.

[@hectoralvarez941]

The wife factor score is like -10. lol. Interesting however 😂

[@AudiophileJunkie]

Yeah... It's going to be tough for even the hubby 🤠

[@TheBlindAudiophile]

yea, just ask my wife. I am always in the dog house. guilty or not

[@MrAlb3rtazzo]

do you people think that he is just telling bs to mislead us ? or he just done not know what Fourier transform is ?

[@barneyrubble9309]

and he'll sell exactly zero units. Seems just another maker trying to find a unique selling point for a product that nobody want or needs.

[@KevinBower-gy5be]

Massively disappointed by the usual easy-to reproduce audio-show fodder for the demo. Why don't any of these companies demo with something complex and with a full-on frequency spectrum where it's often difficullt to separate instruments? Like hard rock or metal? This stuff isn't in any way a proper test IMO.

[@bentonpix]

Squirrel

[@AudiophileJunkie]

Where did you get such extensive vocabulary? 🤠

[@bentonpix]

@@AudiophileJunkie Ha! It was a reference to the movie UP when a squirrel can be seen walking on a branch behind you in the video. All normal interactions suddenly stop when the dog in the movie sees a squirrel and all that is that is said is “squirrel”. My post was probably too random and cryptic for many to pick up on.

[@pedrodepacas4335]

There is something very unnatural about the sound.

[@flex-cx9bi]

Sorry to say it, but this designer have no clue what he is talking about.

[@ronaldmcdonald2456]

Lord help us! That is just SOMUCHSTUFFFFF!!!!!!!!!! Imagine adding all of that to the bazillion big and little BOXES already sprouting from my listening room wall. ''Bus driver, bus driver, open the door(((())))!'' Be ye not surprised when one day you read the headline, AUDIOPHILE'S HEAD SPONTANEOUSLY EXPLODES.
