I would like to draw your attention on 'Seewave', a new tool for sound analysis.
This is a free library written in R language (http://www.r-project.org/).
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
