Notes

To select or de-select all the calls in the Call Labeling screen, do one of the following:

• Click the first check box of the list, near Call Name, to select all calls. To de-select all calls, click that check box once again.
• Right-click somewhere in the call list and select Select All or Select None.

Add a Call Manually

Aim: To add a call that was not detected automatically. The call will be analyzed just as the calls detected automatically. If you want to have the new call analyzed in the same group as the other, automatically-detected calls, rename the new call with the name of those calls. See Rename Calls.

Procedure

1. In the Call Labeling screen, draw a box around the call spectrogram.
2. A new row is inserted. Under Call Name, the text Manual is entered automatically.
3. Optional: Double-click Manual under Call Name and enter the name you require.
4. Optional: Assign a Pattern Label. See Pattern Labels.

Note

If you rename a call with an existing call name (e.g. 45-69k), the cell under Color is updated with the corresponding color.

Edit a Call

Aim: To edit the frequency and time boundaries of a call if they do not match the call spectrogram. Do this for example when the red rectangle around a detected call does not include some weak signal that you believe is part of that call.

Procedure

Adjust the Frequency Boundaries

1. In the Spectrogram, hover the mouse cursor over the upper side (to adjust the High Frequency boundary) or the lower side (to adjust the Low Frequency boundary) of the rectangle around the call.
2. When the mouse cursor turns to a double-headed arrow, drag the boundary up or down to the new position.
3. To save the changes, select File > Save or press Ctrl+S.

Adjust the Time Boundaries

1. In the Spectrogram, hover the mouse cursor over one of the lateral sides of the rectangle around the call, depending on whether you want to adjust the start boundary or the end boundary.
2. When the mouse cursor turns to a double-headed arrow, drag the boundary up or down to the new position.
3. To save the changes, select File > Save or press Ctrl+S.

Notes

• When you edit the frequency or time boundaries of a call, the values reported in the call list for the corresponding call are updated.
• If you adjust the frequency boundaries, the values Freq at Max Amp and/or Mean Amplitude will change.
• If you adjust the time boundaries, one or more of the following values may change: Duration, Start Time (or Stop Time), Freq at Max Amp, and Mean Amplitude.
