ohun is intended to facilitate the automated detection of sound events, providing functions to diagnose and optimize detection routines. Detections from other software can also be explored and optimized.
Details
The main features of the package are:
The use of reference annotations for detection optimization and diagnostic
The use of signal detection theory diagnostic parameters to evaluate detection performance
The batch processing of sound files for improve computational performance
The package offers functions for:
Energy-based detection
Template-based detection
Diagnose detection precision
Improve detection by adjusting parameters to optimize accuracy
All functions allow the parallelization of tasks, which distributes the tasks among several processors to improve computational efficiency. The package works on sound files in '.wav', '.mp3', '.flac' and '.wac' format.
