I would like to draw your attention on 'Seewave', a new tool for sound analysis.

This is a free library written in R language (

It is available on a wide variety of UNIX platforms and similar systems 
(including FreeBSD and Linux), Windows and MacOS.

The main functions are:  oscillogram, envelope, 2D/3D spectrograms, AM spectral 
analysis, automatic silence/signal durations, spectrum, dominant frequency, 
instantaneous frequency by zero-crossing, fundamental frequency by 
autocorrelation, cross-correlation between envelopes, cross-correlation between 
spectra, covariance between spectrograms, sinusoid generator.

Seewave benefits all R high-level graphical specifications: it is possible to 
fully modify the graphics, and to combine the graphical displays of different 
functions in a single multi-framed output. Graphics can be saved in several 
formats, including pdf, with high resolution. Figures are ready-to-edit.

Users can modify the functions, add new ones and run batch processes.

A pps file showing the screen shots and one 3D animation can be downloaded at 
the following link:

For people already used to R, see the 'R' package link with the pdf
