Audio Analysis in R

Jeroen Ooms walks us through some audio analysis with R and the av package:

The latest version of the rOpenSci av package includes some useful new tools for working with audio data. We have added functions for reading, cutting, converting, transforming, and plotting audio data in any popular audio / video format (mp3, mkv, aac, etc).

The functionality can either be used by itself, or to prepare audio data for further analysis in R using other packages. We hope this clears an important hurdle to use R for research on speech, music, and whale mating calls.

One of the most interesting things I saw Edward Tufte demonstrate was visualizing music using the Music Animation Machine. There’s a lot of space here to experiment. H/T R-Bloggers.
