I am thinking of packaging autotalent http://web.mit.edu/tbaran/www/autotalent.html for Fedora, but I first wanted to make sure that license and copyright permitted it.
The source distribution contains the following files: autotalent.c COPYING ladspa.h Makefile mayer_fft.c mayer_fft.h README
The README file says "By Thomas A. Baran", but does not say anything about copyright or license. The file COPYING states the following, which is followed by the text of the GPLv2:
The bulk of the code in Autotalent is released under GPL2. However, the FFT routine was taken from PureData (http://crca.ucsd.edu/~msp/software.html), which was released under a license that is similar to the BSD license. So with the exception of the mayer_fft.* files, everything should fall under GPL2.

The files autotalent.c and Makefile both state that they are under GPLv2+. The file ladspa.h is under LGPLv2.1+
The file mayer_fft.h has no attribution, copyright or license information at all. The file mayer.c has this to say:
/* This is the FFT routine taken from PureData, a great piece of software by Miller S. Puckette. http://crca.ucsd.edu/~msp/software.html */
/* ** FFT and FHT routines ** Copyright 1988, 1993; Ron Mayer ** [Documentation of functions and their signatures omitted] ** ** ** NOTE: This routine uses at least 2 patented algorithms, and may be ** under the restrictions of a bunch of different organizations. ** Although I wrote it completely myself, it is kind of a derivative ** of a routine I once authored and released under the GPL, so it ** may fall under the free software foundation's restrictions; ** it was worked on as a Stanford Univ project, so they claim ** some rights to it; it was further optimized at work here, so ** I think this company claims parts of it. The patents are ** held by R. Bracewell (the FHT algorithm) and O.

/* This is a slightly modified version of Mayer's contribution; write * msp@ucsd.edu for the original code. Kudos to Mayer for a fine piece * of work. -msp */

The license for Pure Data may be found at http://www-crca.ucsd.edu/~msp/Software/LICENSE.txt, and it is indeed a 3 clause BSD type license.
However, it is not included in the source distribution of autotalent, and the ownership of mayer_fft.c seems less than clear to me. Can autotalent be packaged as is? If it can be packaged, do we need to include the Pure Data license file as a second source file in order to comply with that license? Or does "If it were up to me, I'd say go do whatever you want with it" mean we can do whatever we want with it?
Also, the patents in question appear to be U.S. Patents 4646256 and 4878187, which, if I understand correctly, have expired.
Thanks for giving this your attention.

I think that autotalent is fine to be packaged as is, with
License: GPLv2+ and BSD
I would strongly recommend that you include the Pure Data license file, and, if upstream is alive, ask them to do so (and to properly note the license in the mayer_fft* files).

Hi, I have some general questions. What you say above is in direct conflict with the review guideline in [1] which says: "If (and only if) the source package includes the text of the license(s) in its own file, then that file, containing the text of the license(s) for the package must be included in %doc."
My take on this guideline is, we shall put the license file to the %doc that is in the source tarball (necessity) only if there exist one (sufficiency). Thus we are not supposed to include external license files in packages.
The questions are, am I interpreting the guideline wrong? Or are we making an exception for this package? If yes, what grants an exception and is this documented?

Not really, think of it like this:
If (and only if) the source package includes the text of the license(s) in its own file, then that file, containing in the text of the license(s) for the package _MUST_ be included in %doc.
If it does not, and you have sufficient evidence of licensing for a source file, _and_ that source file does not contain a copy of the license text within itself _and_ the license requires that the license text be distributed (for example, BSD does this), you MUST include a copy of that license text. (You should try to get upstream to fix these sorts of situations, as technically, they are also in violation of such licensing terms.)
In all other situations, you are not required to include separate copies of license texts with the Fedora package, however, maintainers may do so at their own discretion.
The questions are, am I interpreting the guideline wrong? Or are we making an exception for this package? If yes, what grants an exception and is this documented?
This is somewhat of an exception, because the BSD license text requires it. Normally, we wouldn't hit this, because the source file would contain the BSD license text within itself, and we wouldn't need to include a separate copy, but in this case, the BSD license doesn't appear anywhere within the autotalent source tarball, but we know mayer_fft.c is BSD.
If the above wording is clear, I'll add it to the Licensing#FAQ.
