4.2 DirectWIRE
What is DirectWIRE?
DirectWIRE is a driver technology, developed by ESI, which can be used for routing audio streams
internally within applications using EWDM Audio MIDI Drivers exclusively developed by ESI.
With the DirectWIRE router, an application can record from other application’s audio outputs
without external wiring or any loss of data when they are running at the same time.
DirectWIRE also allows you to easily rip any audio stream in real time by transferring data thru
DirectWIRE from MP3s, live On-line Broadcast and On-demand content, and more.
DirectWIRE is not available under Mac OS X.
DirectWIRE Panel
Click on DirectWIRE on the U22 XT control panel. The DirectWIRE dialog as shown below will
appear. DirectWIRE digital virtual wiring technology, developed by ESI, routes audio streams
internally within applications using standard audio drivers such as WDM, ASIO and MME, even
when they are running at the same time.
The number on the row represents the input or output port. The columns represent ins and outs (on
and off) of the respected drivers. Patch the virtual cables from one point to another as you drag your
mouse point.
INPUT section: It's used to route signals from the card's hardware inputs.
MME section represents general applications I/O (typically older versions), like WinAmp,
WaveLab (non ASIO mode), Cakewalk, Audition, Vegas, etc.
WDM section represents Multi-MME applications I/O (typically newer versions), like SONAR
(when using WDM/KS), PowerDVD, WinDVD, etc.
ASIO section represents ASIO applications, like Cubase, Reason, Nuendo, SONAR (when using
ASIO), Samplitude, etc.
GSIF section represents GSIF application like GigaStudio.
Note that some applications support multiple driver modes. Usually the following applies: when an
application does not support ASIO, it usually supports WDM. Older programs typically support
MME.
