PAM2py

download zip or github, a Python open source version of the PAMGuide package for Passive Acoustic Monitoring that features the Exchange Data Format (EDF) for facilitated underwater acoustic data sharing and metadata handling. Python allows for a crossplatform licence free processing of raw acoustic data and EDF output. A library of Python routines for EDF data reading and writing are also available. See manual here.


Head wave propagation using Traceo

TRACEO

an efficient Gaussian beam 2D ray tracing model for underwater acoustic propagation, handling full bottom and water column range dependency, obstacle scattering and producing particle velocity outputs. See manual here and download a free copy for Fortran. A C version for linux and/or Windows is available here and for GPU here.
