The OBI (Octave Band Intensity) detector finds boats by looking for variations in the
sound intensity within the 2nd, 3rd, and 4th octave band, centered at 125 Hz, 250 Hz, and 500Hz.
The performance of the OBI detector can be optimized by adjusting the parameters found in the [obi.json](detectors/obi.json)
configuration file. While this file contains many parameters, the most relevant are the `prominence` and `multiplicity`
parameters (found in the `detect_config` section). The former determines how prominent the increase in the
sound intensity must be to be counted as signal, while the latter determines in how many octave bands such
a signal must be detected in to produce a boat detection.
