Bjørn Forsman e8c22b33e6 baudline: init at 1.0.8
Baudline is a scientific signal analysis application.

I was unsure whether the baudline license allowed packaging in nixpkgs,
so I sent a copy of this nix expression (and some explanation) to their
support. I got this reply:

  Hello Bjorn,

  This sounds fine.  What you suggest doing is very similar to how the
  FreeBSD FreshPorts system deals with baudline.

So basically, everything is good as long as we only distribute the _expression_
to install the package. We must not distribute the package (binary).

Baudline is a time-frequency browser designed for scientific
visualization of the spectral domain. Signal analysis is performed by
Fourier, correlation, and raster transforms that create colorful
spectrograms with vibrant detail. Conduct test and measurement
experiments with the built in function generator, or play back audio
files with a multitude of effects and filters. The baudline signal
analyzer combines fast digital signal processing, versatile high speed
displays, and continuous capture tools for hunting down and studying
elusive signal characteristics.
