Dear all
I would like to perform frequency analysis of a sound (noise) recorded as a wav file (I would like to compare different sounds if they vary in frequency and how much). I know there exists some packages (Cool Edit) for doing frequency analysis of sounds but I wonder if anybody tried to do it in R.
I found a package sound. It enables to play with wav files, to append them and to make some filtrations. But if I wanted to invoke a spectrum() function it did not work with sound object.
Please can somebody give me a hint where to look or how to convert wav file to some kind of object analysable by R functions.
If you did mywave <- loadSample(.....) the data you are trying to analyze is in the matrix mywave$sound
