Software
--------

Below is a list of software resources for processing ocean sonar data.
When appropriate, we note whether the software is proprietary or open-source,
as well as the programming language in which it is written.

- `EchoView <https://www.echoview.com/>`_:
  a GUI-based proprietary software,
  the current go-to tool for echosounder data analysis
