For offline analysis the OfflinePlayer application takes as parameters a 
network and any input and output wav files as sinks and sources the network 
takes. For realtime applications, Prototyper is the equivalent which takes 
the audio from audio device I/O instead and you can provide an optional user 
interface built with Qt Designer.

If you really want a real stand alone application (no network file required) 
we are very close to get single click binary generation by embedding the 
network into the binary as data. It is already doable by hand, but this would 
require further instructions.

Yes you are right. The example uses dummy datatypes. In your case you should 
just get a CLAM::Fundamental input port which requires #include 
<CLAM/Fundamental.hxx>. You can remove the output port and the code that uses 
it.

If you use directly the fundamental, you can just forget about controls (and 
the related wiki too).

In the Do method:
TData fundamentalFreq = _inPort.GetData().GetFreq(0);
Then, write fundamentalFreq wherever you want.
