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: From: Erik Olson <erik@sigblips.com> Subject: Re: Licensing question Hello Bjorn, This sounds fine. What you suggest doing is very similar to how the FreeBSD FreshPorts system deals with baudline. Erik 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.
