soundecology

R package with functions to calculate indices for soundscape ecology and other ecology research that uses audio recordings.

Indices:

• Normalized Difference Soundscape Index (NDSI) from REAL and Kasten et al. 2012.
• Acoustic Complexity Index (ACI) from Pieretti et al. 2011.
• Acoustic Diversity Index (ADI) from Villanueva-Rivera et al. 2011.
• Bioacoustic Index from Boelman et al. 2007.

Other functions:

• measure_signals() - This function lets the user select bounding boxes to get statistics of the signals of interest in a sound file.
• multiple_sounds() - Function to extract the specified index from all the wav or flac files in a directory. The results, including the filename and wave technical details, are saved to a csv file. If the computer has multiple cores, it can run files in parallel.
• sound_raster() - This function creates a raster file in ASCII format from the spectrogram of a soundfile.

The package is available from CRAN: http://cran.r-project.org/web/packages/soundecology/
