Poor detection with low intensity and step USVs about deepsqueak

[cmlenell1]

Also, with step vocalizations (both step-up and step-down) like the second example, the contour detection sometimes picks up the step if I redraw the box so that the box is on top of the step part of the USV.

The contour detection only works within the boxes. I think a lot of those calls are so quiet that they are pushing the signal to noise limits on our detection network. You can play with the slider next to the tonality graph to optimize contouring.

One option to help with picking up the steps is to expand all of the boxes vertically. We didn't do that initially because it could grab low frequency noise, but we can try to add a tool that lets you make all boxes extend from 30-90 khz. It might take us a minute to get around to it.

I've added a function to set the upper and/or lower frequency of each call to a constant value. If the boxes are at the right places in time, this might help with detecting steps outside of the box.

Its located under "Tools > Automatic Review > Set Static Box Height".

Hey cmlenell1,

I think that is about all we can do with these low intensity calls. I'm going to close this issue, but feel free to open another.
