[LAU] Analysis of monophonic audio signals on the commandline

[Jeanette C.]

Hey hey,
I am looking for tools to analyse bird song. I have many recordings, which can 
probably be cleaned up enough to have single calls as good as isolated. On the 
other hand there are quite a few sonograms of bird calls, used to identify 
species.

What I am looking for is a kind of mathematical analysis tool to get an idea 
of frequency and volume, perhaps with an estimate of curves. I suppose that 
requires statistical analysis. This is far from my forte, so I wouldn't know 
which keywords for the relevant math to enter and in which tool to look. Are 
there audio specific programs? Or is a math package like R, octave or maxima 
able to handle such data input and the task?

If you are not immediately aware of a relevant tool, but could supply me with 
a few keywords and considerations, that would already be quite helpful.

Best wishes,

Jeanette
