It would be useful to create a C++ hierarchical block that encapsulates an
audio source and exposes accessor methods to manipulate the gains and
filters.  See the pattern for the gr_channel_model block in the
gnuradio-core/src/lib/hier directory.  This would allow use from C++,
Python, and GRC apps.
