First of all, I'd like to thank you for the fast answer on the bug report. Mark Purcell wrote: > [...] > This has already been discussed in Bug#419597. [...]
Having just reread that bug, I still believe it does not refer at all to the problem reported by me. Bug #419597 was about the usage of patented technics in mp3 (seemingly accidently filed against an mp2 implementation). Later on, the discussion switched to mp2 patents in general. However, this bug (#569228) is about the usage of a routine in *this specific implementation* of mp2, which might be covered by patents and/or use LGPL-incompatible code. Of course, the patents might already have been expired (this does not seem to be improbable). But by carefully reading the full comment in the source code, it is still possible to arrive at the conclusion, that some parts of the code aren't free of copyright restrictions, which might make it unfit for release under the LGPL. Kind Regards Willi Neudeck PS: I have just read in the wikipedia article about the Discrete Hartley transform [1], that the patent on FHT has been put in the public domain by Stanford University in 1994. Therefore, at least one of the problems seems to have disappeared.
