maybe i'm just completely blind, but i cannot
find any DFT/FFT routines in the library yet?
are they hidden somewhere-- or are they to
be imported into the project anytime soon?
The open source Framewave project does not currently have any DFT or FFT routines. In the proprietary version (APL), portions of the FFT library were dependant on a commercially licensed version of FFTW. Due to license restrictions, we can not open source this part of the library.
For general FFT development we recommend that you look into AMD’s ACML http://developer.amd.com/tools/acml/Pages/default.aspx. If you need an open source solution, try http://www.fftw.org/.
If you need to retain API compatibility with APL, we have developed wrappers that provide an APL compatible interface on top of FFTW. If there is interest, we can release these as sample code on the download site.
