Manipulating Streams With VMODE

New in Element 2.x, VMODE is an extension of the
VMIX functionality. Its controls are found exclusively
on the StudioEngine's
V-Mixer & V-Mode
and are not duplicated or accessible from the Element
web pages.

What does VMODE do?

As you know, audio processing in the modern world
requires DSP. The StudioEngine provides the DSP for
Axia IP-Audio networks.
You've probably noticed that nearly all audio within
an Axia network travels in stereo. Audio Node inputs
(with the exception of Mic Nodes) are stereo, and so are
Engine default sources. Most of the time, this is just what
you need. But in some cases, an application surfaces that
requires only one channel of an audio stream, or a mono
sum. Until now, there was no easy way to make this hap-
pen.
Vmode is a new addition to the Element toolbox that
addresses this requirement; its job is to help strip, sum,
or compile a custom audio stream from available streams
in the network.

VMODE Controls

VMode, as shown in Figure 6-4, has the capacity for
up to eight separate stream-manipulation operations. The
controls are as follows:
• Input Selector
allows you to select from a range of sources for
HTTP page, each VMODE input. You may choose from
1/2/3/4,
A/B/C/D, VMIX SUB 1/2/3/4/5/6/7/8,
VMIX MAIN.
then allows you to select any network source by en-
tering its channel number.
• Src Name
Selector
may type any conveniet title in the
to identify the source; the

you want to perform a VMODE operation upon.
