We believe in our products, and we're sure that they'll work great for you. However, there's not always a one-size-fits-all solution when it comes to vibration control. If not satisfied, simply return any Herbie's Audio Lab product within 60 days for a full refund of the purchase price.
Vibration Audio aims to produce the most efficient and accessible lithium batteries for use in car audio installations. Their expertise is derived from competing in car audio SPL lanes themselves and building some of the most insane lithium banks for heavy SPL competitors.
Anti-vibration stands are designed for high end audio components. The frame has been tuned by a suitable combination of alloy steel and high-fiber content steel. The frame consist of extra-strong legs made of carbon steel S235JR (which is used for load-bearing stuctures subject to heavy dynamic load, e.g. in cranes) connected by crosspieces made from higher-strength alloy steel S355. Adjustable anti-vibration spikes are used for for high-precision leveling.
A unique feature of our company is extreme flexibility. Some modifications are possible and as a result each product is manufactured on a made-to-order basis. As a result, your furniture will be suitable for the size of your audio equipment, it will match the dcor of the interior in which it is displayed, and it will reflect your personal taste. Alterations of our standard products are priced individually. Possible changes involve:
"iphone x no audio or vibration: My iphone X has no audio or vibration at all. when i go to play a video that has audio it crashes. Only in calls do i have audio but there is a very loud static noise."

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.
Heather Kelly of CNN reports on how MIT researchers have developed a new technique to recreate audio from silent video. "We showed that we can determine pretty reliably the gender of a speaker from low-quality sound we managed to recover from a tissue box," says Dr. Michael Rubinstein.
Bloomberg Businessweek reporter Drake Bennett writes about how MIT researchers have developed a technique for extracting audio by analyzing the sound vibrations traveling through objects. Bennett reports that the researchers found that sound waves could be detected even when using cell phone camera sensors.
Alyssa Newcomb of ABC News reports on how MIT researchers have developed a new method that can uncover intelligible audio by videotaping everyday objects and translating the sound vibrations back into intelligible sound.
Writing for Slate, Elliot Hannon reports on the new technology developed by MIT researchers that allows audio to be extracted from visual information by processing the vibrations of sound waves as they move through objects.
Hal Hodson of New Scientist reports on the new algorithm developed by MIT researchers that can turn visual images into sound. "We were able to recover intelligible speech from maybe 15 feet away, from a bag of chips behind soundproof glass," explains Abe Davis, a graduate student at MIT.
When playing a cassette tape in my new audacity player there is a very loud (louder than the music) vibration sound. It is a constant pounding sound. Any idea what it is and how can it get rid of the annoying noise? thanks for your help
All products driven by electronic and/or mechanical means have characteristics known as vibrations forming amplitudes of resonance energy, which greatly inhibits the overall performance and operational efficiency of the said product. Live-Vibe...
My own experience showes that both could be used sucessfully. However, the key is to find which component is better served by one or both methods. These two method will change the SQ dramatically so one needs to find the right balance.
A good example is my PST since it is more sensitive than others in my system. I have experienced with PST using different types of cones, dampers, Duro70 rings, metal supports. I have settled on these for the last year

So, I replaced the duro70 rings with duro70 sheet to reduce the damping quantity, and I use three instead of four columns under PST. I replace the duro disc with sheet on power plug too:

The improvement on vividness, dynamic and detail is quite noticeable. It seems that I used a bit too much absorbing material in the past. Yes, I did try the metal supports without any duro70 at all, and I did not like the result. The SQ is a bit too jumpy and gets brighter. So, this is the best supports I found for my system, for now.
Is it for a unit which causes vibration itself or not?
Is the unit prone to airborne noise or not?
Is the base absorbing deducted vibration of the feet or not?
Is the base itself or the rack under it affected of airborne noise or floor vibrations (from a subwoofer etc.)?
Does the component you want to resonance control have a kind of sound that needs to be influenced in tonality or not?
Is the floor soft, solid, concrete or floating?
Does the room/flat below have to be isolated from the resonance noise above or not?
Depending on all of this, the rough decisions (resonance derivation or absorption) have to be made (possibly in several alternating combinations) and then the more detailed ones. The choice will be different for every record player, CD drive or speaker (even in the same environment and even more in differing environments).
One of the biggest jokes is that Rega, who have obsessed about vibration control for 50 years, spent a year developing the material for the feet of the Rega P10 and some people think they can do better with some generic after-market product that costs a fortune.
There are too many variables to consider I agree. One has to try different footers to decide which one is preferable to his/her system. For instance, I still prefer Orea footers under the BHK pre more than my metal/sorbothane combo under PST. By the way, these metal supports have three ball bearings in each of them, and I prefer the ceramic balls than steel balls, I think.
These fancy footers surely look expensive. Footers can tune SQ (in addition to their main function: vibration absorption/transferring), and in some cases they can make quite an impact. They are system dependent too (may be more audio rack dependent).
I settled with my homemade metal/sorbo supports for PST and Lumin U2 (clearly better than others), and I like them under LHY SW-10 switch too (surprisingly how a switch can be affected by footers). But MK2 and BHK pre are better off with Oreas. Somehow, I am losing detail and life with metal supports under them, but it is the oppsite when they are under PST and Pre. Very interesting!
I am trying to perform a vibration in an app similar to Snapchat, that uses both audio output and input as well as supports audio mixing from other apps, but this seems to be a harder task that I initially thought it would be. Important to know is that I am not trying to vibrate during playback or recording. From reading all the documentation I could find on the subject, this is what I have come to understand:
This successfully performs the vibration, but afterwards, when I try to record a movie, the audio is ducked (or something else is causing it to be very silent). It also gives me an error saying that I am not allowed to deactivate a session without removing its I/O devices first.
This solution comes up every now and then, but does not seem to work for me. No vibration occurs, even though the categories seems to be set. This might still be a valid solution if I set usesApplicationAudioSession = YES on my AVCaptureSession, but I haven't made it work yet.
For reference, I'm not using AVCaptureSession but an AVAudioEngine to record something, and for my case I pinpointed it down to having to pause the input in order to play the vibration properly with AudioServicesPlaySystemSound during a record session.
I aim for /haptic/ feedback when a person touches different plates. When touching each plate the person controls pitch frequency content and/or rhythmical texture of an audio stream. The haptic feedback should feel connected to the sound but does not have to be in synk with pitch frequency.
I use a Nano to communicate serial data over USB to audio software (PureData). The sound is controlled through analog inputs. Then I will translate the audio stream(s) to serial data and send this to the Nano output pins (digital or PWM).
