Convert raw PMAR files

Guide for converting raw PMAR .dat files to .wav or .flac

agate includes utilities for converting raw PMARXL acoustic files (.dat) into a more easily readable .wav format. An example workflow is provided in the agate\example_workflows folder and detailed instructions are below.

Dependency references

A function-ized and modified version of the convertPmar.m script and associated function pmarIn (written by Dave Mellinger and available in the Mathworks File Exchange: convertPmar) are included in agate.

Example workflow

The script and function have been modified and combined to work within agate. The input CONFIG files are populated from a PMAR-specific configuration (.cnf) file. An example can be found in the agate/settings folder.

See workflow_convertPMAR.m in the example_workflows folder for a simple example workflow for converting a mission’s PMAR .dat files to .wav.

Like other workflows in agate it must first be initialized with a mission-level configuration file (e.g., agate_config_example.cnf). Only the top REQUIRED and CONFIG.pm settings in the OPTIONAL - acoustics sections of the configuration file are needed for file conversion.

Additionally, a PMAR conversion configuration file (e.g., pmarConvert_example.cnf) is needed. This contains the specific paths and is where you can set your desired conversion settings. Detailed descriptions of each parameter setting are in the example configuration file.
