TwinTube Analog Code® Plug-in 5
Introduction
The Analog Code®
While SPL hardware products have been fascinating audio pro-
fessionals from home studio owners to mastering engineers in
the world’s most renowned facilities for years, the need for this
technology in the form of plug-ins has also been an ever-growing
demand. With the Analog Code® plug-ins we have finally accom-
plished our much desired goal: to transfer to the digital domain the
high quality we have striven to achieve with our analog processors
throughout several decades.
The first time we ever heard a software that fulfilled our expecta-
tions, one of our hardware developers said to the programmers:
“you have cracked the Analog Code” — thus was coined the name
of our digital products.
TwinTube
The TwinTube module is the first combination of two essential tube
effects in a single processor, that is, saturation effects along with
harmonics processing. Both stages work separately from each
other and are based on individual processing stages. The effects
can therefore not only be applied both individually or separately,
but also in common.
In the original analog design, the saturation effects are generated
through the tube being pushed to and beyond its normal operating
limits. In contrast to semiconductors, a tube thus pushed to such
levels does not clip from a certain level, approaching more gradu-
ally its level limits and thereby producing its typical tonal result,
which in audio signal processing can have such often profitable
aural effects. >
