createOctaveLevel

Creates octave or third octave level measurements from finer
resolution soundscape metrics, like Power Spectral Density (PSD) or
Hybrid Millidecade (HMD) measures

A variety of tools relevant to the analysis
of marine soundscape data. There are tools for downloading AIS (automatic identification system)
data from Marine Cadastre <https://hub.marinecadastre.gov>,
connecting AIS data to GPS coordinates, plotting summaries of various soundscape
measurements, and downloading relevant environmental variables (wind, swell height) from the
National Center for Atmospheric Research data server <https://rda.ucar.edu/datasets/ds084.1/>.
Most tools were developed to work well with output from 'Triton' software, but can be adapted
to work with any similar measurements.

<dd>dataframe of soundscape metrics</dd>
<dt>type</dt>
<dd>either <code>'ol'</code> to create octave level or <code>'tol'</code> to create
third octave level measures</dd>
