bioacoustics: detect and extract automatically acoustic features in audio recordings


bioacoustics contains all the necessary functions to read audio recordings of various formats, filter noisy files, display audio signals, detect and extract automatically acoustic features for further analysis such as species identification based on classification of animal vocalizations.

It can be subdivided into three main components:

  • Read, extract data (not yet implemented), display, and write Zero-Crossing files.
  • Stand-alone tools to convert MP3, WAV, and WAC files.
  • Read, display, MP3, WAV or WAC files, filter, and extract automatically acoustic features.


  • Install stable version from CRAN:
  • Install development version from GitHub:
# install.packages("devtools")
devtools::install_github("wavx/bioacoustics", build_vignettes = TRUE)


Installing bioacoustics from source works under windows when Rtools is installed. This downloads the system requirements from rpkg-libs.


For Unix-alikes, FFTW (>= 3.3.1) is required.
