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: a GUI-based proprietary software, the current go-to tool for echosounder data analysis
EchoR: an R package to handle pre-processed fisheries acoustics data collected during sea surveys and to produce and analyse ec(h)osystem indices and maps based on fisheries acoustics data
ESP3: a Matlab package for sonar data analysis.
ExCal: a Matlab package to calculate calibration coefficients for EK/ES60 echosounders.
LSSS (Large Scale Survey System)
MATECHO: requires Matlab and Movies3D
Movies3D: reads and writes HAC files and is capable of joining EK60 and ME70 data
PyEchoLab: an open-source Python package based solely on the NumPy library
