The History of Wheatstone Audio Processors

Introduced in 2005, the Vorsis product line evolved from Wheatstone’s return to

its original roots in audio processing. Having designed and integrated analog and

then, later, complex digital audio processing into our radio and television consoles

and control surfaces, Wheatstone was perfectly poised to address the challenges of

combining very high audio quality with competitive on air loudness.

Wheatstone audio processors are built to the same exacting standards as all

Wheatstone products. Research and development, manufacturing, testing, and qual‑

ity control for the line of audio processors are all accomplished within Wheatstone’s

large state‑of‑the‑art facility located in New Bern, North Carolina. Keeping everything

under one roof allows Wheatstone to have control over every facet of production

and ensures that our costumers receive products of the highest possible quality and

reliability. Staying true to “Made in the USA,” Wheatstone does not utilize offshore

manufacturing.

A dozen experts with deep experience in Digital Signal Processing, broadcast

audio and other engineering disciplines comprise our design team. Led by audio

processing expert and broadcast engineering veteran Jeff Keith, the team combines

their talents to design and build audio processors that achieve the highest standards

of on‑air sound quality.

In its short history Wheatstone Processing has already invented many new and

unique audio processing algorithms – algorithms that push audio processor performance

to new and higher levels. Wheatstone was the rst to develop an intelligent, “program

density aware” AGC (2007 - Sweet Spot Technology, or SST). We were also the rst

to employ the science of human psychoacoustics in the design of a multiband limiter

(2005, our acclaimed and patented 31‑band limiter). In addition, our well‑regarded

Bass Management systems solve the bass intermodulation problems that plague other

brands of audio processors when pushed for competitive loudness.

Each Wheatstone Processing product comes with its ownWindows®software‑based

intuitive Graphical User Interface for control of the processor. Carefully tuned factory

presets ensure that our audio processors can be placed into use quickly and easily in

any size market with a minimum of effort.
