+#Proposed Approach:
+#1. Assume that a long recording has been broken into one-minute segments.
+#2. Convert each one-minute segment to a spectrogram.
+#3. Obtain a noise profile for each segment. This is to be used later to remove insect chorusing.
+#4. Scan the one-minute waveform and select "spike maxima" whose amplitude exceeds a decibel threshold, D.
+#5. Extract a single frame (say 512 samples) centred on each spike and convert to a spike spectrum.
+#6. Subtract the noise profile from the spike spectrum.
+#7. Smooth the remaining spectrum.
+#8. Look for evenly spaced harmonics in the smoothed spectrum.
+#    Typically the lowest harmonic will lie between 1200 Hz and 3000 Hz and the higher ones evenly spaced.
+#    This is the tricky bit due to variability but may work to use spectrum auto-correlation.
+
+# Each of these profiles will be analyzed
+Profiles:
+  #Standard: &STANDARD
+  #EventThreshold: 0.2
+  # Common settings
+  #BgNoiseThreshold: 3.0
+  Territorial:
+    # min and max of the freq band to search
+#    MinHz: 800          
+#    MaxHz: 8000
+#    MinDuration: 0.15
+#    MaxDuration: 0.8
+#    DecibelThreshold: 9.0
+  Wingbeats:
+#    MinHz: 200          
+#    MaxHz: 2000
+#    DecibelThreshold: 6.0
+    # duration of DCT in seconds 
+#    DctDuration: 0.5
+    # minimum acceptable value of a DCT coefficient
+#    DctThreshold: 0.5
+    # ignore oscillation rates below the min & above the max threshold
+    # A sample of four wingbeats yielded an average of 5.1 +/-0.5 beats/s.
+    # 95% confidence interval (2 SDs) is therefore approx 4-6 beats/s.    
+    # OSCILLATIONS PER SECOND
+#    MinOscilFreq: 4        
+#    MaxOscilFreq: 6
+    # Minimum and maximum duration for the length of a true call.
+#    MinDuration: 1.0
+#    MaxDuration: 10.0
+    # Event threshold - use this to determine FP / FN trade-off for events.
+#    EventThreshold: 0.5
+  #Agonist:
+  # This notation means the Groote profile has all of the settings that the Standard profile has,
+  # however, the MinHz and MaxHz properties have been overridden.
