Detecting chirps with a few terminal commands

Once everything is set up correctly, detecting chirps is a breeze. The terminal utility can be called by chirpdetector or simply cpd.

Simply run

cpd detect --path "/path/to/dataset"

And the bounding boxes will be computed and saved to a .csv file. Then run

cpd assign --path "/path/to/dataset"

to assing each detected chirp to a fundamental frequency of a fish. The results will be added to the .csv file in the dataset. To check if this went well, you can run

cpd plot --path "/path/to/dataset"

And the spectrograms, bounding boxes, and assigned chirps of all the detected chirps will be plotted and saved as .png images into a subfolder of your dataset.

The result will look something like this:

15 seconds of a recording containing two chirping fish with bounding boxes around chirps and dots indicating to which frequency they are assigned to.
