Separate Long 22s

Particularly for rat long 22s, the detection algorithm may place multiple calls into a single box.

To separate these calls, we apply k-means to the tonality, and create new boxes from unbroken regions of high tonality.

To separate calls:

1. Select "Tools > Separate Long 22s"

2. In the dialog box, select the detection file.

3. In the dialog box, select the correspond audio file.
