this is my proposal. Note the use of Network::AddSubNetwork and the way
to create "virtual" in/our ports using sources/sink processings.


void testAnalysisSynthesisInaNetwork()
{
     CLAM::Network net;
     CLAM::Network anaysisNetwork;

     CLAM::FreewheelingNetworkPlayer * player =  new 
CLAM::FreewheelingNetworkPlayer;
     net.SetPlayer( player ); // network owns the player memory

     analysisNetwork.AddProcessing( "Source", new CLAM::AudioSource ); 

     analysisNetwork.AddProcessing( "Sink", new CLAM::SinPeaksSink );
     analysisNetwork.AddProcessing( "Analysis", new CLAM::SMSAnalysisCore );
     analysisNetwork.ConnectPorts( "Source.AudioOut", "Analysis.Input 
Audio" );
     analysisNetwork.ConnectPorts( "Analysis.Sinusoidal Peaks", 
"Sink.Sinusoidal Peaks" );
     analysisNetwork.ConfigureProcessing("Analysis", 
helperAnalysisConfigInstance() );

     net.AddProcessing( "Source", new CLAM::AudioSource );
     net.AddProcessing( "Sink", new CLAM::AudioSink );
     net.AddProcessing( "Synthesis", new CLAM::SMSSynthesis );
     net.AddSubNetwork( "AnalysisNetwork", analysisNetwork );

     net.ConnectPorts("Source.AudioOut", "AnalysisNetwork.Source"); 
//note the use of the source/sink name identifyer.
     net.ConnectPorts("AnalysisNetwork.Sink", "Synthesis.InputSinPeaks");
     net.ConnectPorts("Analysis.Residual Spectrum", 
"Synthesis.InputResSpectrum");
     net.ConnectPorts("Synthesis.OutputAudio", "Sink.AudioIn");
     net.ConfigureProcessing("Synthesis", helperSynthesisConfigInstance() );

... the rest is the same as the original...
