soundgen

R package for sound synthesis and acoustic analysis.
Homepage with help, demos, etc: http://cogsci.se/soundgen.html
Source code on github: https://github.com/tatters/soundgen

Performs parametric synthesis of sounds with harmonic and noise components such as animal vocalizations or human voice. Also includes tools for spectral analysis, pitch tracking, audio segmentation, self-similarity matrices, morphing, etc.

Key functions:

  • Sound synthesis from R console: soundgen()
  • Shiny app for sound synthesis (opens in a browser): soungen_app()
  • Acoustic analysis of a wav/mp3 file: analyze()
  • Shiny app for editing intonation contours (opens in a browser): pitch_app()
  • Measuring syllables, pauses, and bursts in a wav/mp3 file: segment()

For more information, please see the vignettes on sound synthesis and acoustic analysis:

vignette("sound_generation", package="soundgen")

vignette("acoustic_analysis", package="soundgen")

Or, to open the vignettes in a browser:
RShowDoc('sound_generation', package = 'soundgen')

RShowDoc('acoustic_analysis', package = 'soundgen')

Installation

To install the current release from CRAN: install.packages("soundgen")

NB: Make sure all dependencies have been installed correctly! For problems with seewave, see http://rug.mnhn.fr/seewave/

On Macs, you may need to do the following:

  • First install brew according to the instructions here: https://brew.sh/
  • Then run the following from the terminal
    brew install libsndfile
    brew install fftw
  • Finally, install soundgen in R:
    install.packages("soundgen")
