Introduction
The PCIe DAB+/DAB radio capture card receives and decodes the entire
contents of up to four DAB+/DAB ensembles, rendering each audio service
as a virtual Windows audio capture device for use with multi-channel
recording or monitoring software.
Broadcast data services, including DLS text and MOT slideshows, are also
available through a simple application programming interface.
The card supports both legacy DAB MP2 audio coding as well as the new
HE-AAC v2 encoding used with DAB+ broadcasts.
Any application that records from standard wave input devices can be used
to record the audio streams from the DAB+ Radcap. A recording level and
mute control are provided for each service through the devices’ mixer
ports.
A sample monitor application is included which displays a control panel
for each card and creates buttons for each audio service. When a button
is clicked, it plays the audio through the default output device while
displaying information obtained from the service and any DLS text and MOT
images being broadcast.
The number of ensembles is factory-set as 1 (PC-DAB1), 2, 3 or 4 (PC-DAB4)
but is field-expandable through a purchased expansion key. Multiple cards
can be installed, allowing simultaneous monitoring or recording of more
than four ensembles.
A sample application is provided with the card, allowing monitoring
of DAB+/DAB audio and data as well as providing diagnostic ensemble
spectrum displays, signal quality indicators and an uncorrected error
counter. Each card panel displays the ensemble name and identifier, along
with the phase reference correlator level and signal spectrum.
