the Windows audio subsystem does not support recording directly in the
DAB+ / DAB native AAC or MP2 compressed formats.
Monitor Application
A simple monitor application is included in the distribution package, along
with its C++ source code utilising the DAB+ Radcap programming API
documented in Appendix A. Two versions are supplied, one based on the
WinMM (wave) API and the other on DirectShow.

The application displays a control panel for each ensemble 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.
Each ensemble panel displays the ensemble name and identifier, along with
the phase reference correlator level and signal spectrum. A drop-down list
allows the ensemble channel to be set.
The buttons corresponding to each audio service are sorted by service ID
number (SId). The application periodically scans the list of audio capture
devices, adding, removing or renaming buttons as required.
