AudioRail® Technologies

AudioRail® Technologies has retired its ADAT rx32tx32 product and is no longer in volume production. We have a limited supply of AudioRail® units that we will sell to existing AudioRail® customers only.

We will continue to support existing customers and honor our product warranty. Please do not hesitate to contact us for technical support of any kind. We still have a limited supply of new, used, and loaner units available to support existing AudioRail® customers.

Since the 3.3V power connector problem was resolved in 2007, we have not heard of any AudioRail® failures in the field. Recently a customer overseas returned from the pandemic to his large studio in California, upgraded his computer equipment, and found that AudioRail® no longer worked. He was initially requesting loaners or replacements, and we were in dialog and preparing to accommodate him, but then he figured out that the problem was that his RME ADAT sound cards needed a firmware upgrade, which fixed the problem. He was among our first customers and had been using AudioRail® for nearly twenty years, and continues to do so so as of this writing (mid-2023).

The AudioRail® story:

AudioRail® Technologies designed and developed an intended series of digital audio snake products, with patented technology built from scratch. The first (and only) product on the market, the ADAT rx32tx32, began shipping worldwide in February 2004. Other products were designed and prototyped, but never produced.

AudioRail® Technologies was and is a "family and friends" based high-tech home business. It was always a debt-free, self-funded, zero-risk venture.

Although we have a solid worldwide base of happy customers, sales for the flagship product steadily declined to the point that it was no longer profitable to us.

In the "audio snake" market, analog multicore snakes continue to be the main trusted technology utilized by low-end users. Meanwhile, high-end users tend to choose much more expensive digital snake solutions, and the companies making digital mixing consoles continue to roll out their own custom, proprietary "Cat5" digital snake extensions. In Europe, another small company introduced a competing product which can be acquired in the EU without customers incurring the import fees and shipping cost of acquiring AudioRail® directly from us in the U.S.

We also suffered a major death in the family in 2011, which affected "company" morale and the desire to continue in active business, along with the steadily declining sales.

Again, we are still here as a "business" to support existing customer needs. Please e-mail us; the business telephone line has been retired.

The technology is still covered by an active patent, so the intellectual property and various other assets are still available for license or sale. One key feature that we never saw matched was the extremely low latency, consistently under 5 microseconds (approx. 4.5 μs + 0.25μs/hop + 0.005μs/meter, end to end) which is a small fraction of a standard 48 KHz sample, as well as the simplicity and low cost of the implementation. Other businesses and entrepreneurs should not hesitate to contact us at for any corresponding inquiries.
