Nice to know that. Oh, just one thing (I have not checked the svn repo
yet): are you compiling djbfft as a shared object?

Well, I'm not sure how the fft libraries perform these days, but I think
that doing a small benchmark would be useful. Especially for arches that
are less popular, like ppc.

calculations; the same is true for lossywav.
Sure, lame does not use, but I'm thinking of getting rid of the assembly
specific parts (as much as I can---see the executable stacks problems that
we had recently).
BTW, can you check out the lame CVS repo and criticize the Debian
packaging? I'm willing to make major surgeries there, now that we're in
plain development cycle of lame 3.99.
OK, back to the djbfft, lossywav is only implemented in pascal/delphi and I
am planning a C port of it, where I would need a FFT library (to avoid
reinventing the wheel).
Would you like to join forces and transcribe the code from pascal to C, so
that we can have lossywav working for a broad range of platforms? I can add
you to the sf.net project (named lossywav, of course).
Regards, Rogério Brito.

I tried out the Gentoo patch which builds the library into a shared onject (and it works fine), but I decided against it because (1) the djbfft code is not going to change and the API is stable anyway so static linking should be just fine and (2) djbfft is chosen for its high performance and dynamic linking would be a drawback in this regard. So I decided for building static libraries (the normal one and an additional PIC-flavour), but this is subject to change.

This will be highly appreciated among distributors, I believe (given that the performance drawbacks aren't too severe). BTW, can you check out the lame CVS repo and criticize the Debian packaging?

I'm not sure right now, but I think that some functions of lame (OK, not
packaged in Debian) and lossywav (still not packaged) might benefit from
a Fast Fourier Transform.
