- Of particular interest to many users will be the CPU load (excessive CPU load may cause sluggish behaviour or freezing of the computer), and Audio latency. Apart from DDC bandwidth, CPU load may be minimized by reducing the Demodulator filter length (...
- Note: When measuring sensitivity using SINAD, it is very important that the Audio Filter is enabled and the cut-off frequencies (and for FM measurements, also the de-emphasis) are set according to the specified test conditions. Proper audio filtering ...

By pressing either (or both) of the Left or Right buttons, you can channel the
currently selected receiver’s audio to either the left or right (or both) audio
stereo channels.
Note however, that in order to be able to simultaneously listen to a receiver
that is not currently “in focus” (i.e. it is not selected by its associated tab), you
will need to disable the “Auto-mute RX not in focus” option under the
Options top bar menu.
Virtual Sound Card
The Excelsior receiver is equipped with an interface to the WiNRADiO Digital
Bridge™ Virtual Sound Card.
The Virtual Sound Card (VSC) is a software option designed to transfer
digitized audio signal streams from WiNRADiO receivers directly to other
applications. It does so by creating a Windows multimedia driver which will
make the WiNRADiO receiver appear to the system as another sound card.
Third party software applications which would normally rely on a sound card
input as the signal source (such as various data decoders), can access
digitized data (either undemodulated IF signal or demodulated audio) directly
from the WiNRADiO receiver, eliminating unnecessary conversions between
the digital and analog domains, reducing distortion and improving signal
quality. For more information about the VSC, please refer to the webpage
