I have more in common with a marsupial probably genetically that the big E but I'm willing to slog at it. Perspiration + Inspiration. Catching me working and all that.
No rush, the conversion can wait. I'm just keen to do some freq-domain do-hickery. It' ll probably explode the kindle.
That said I do have a very nice comfortable overhead when I use a 3 frame refresh - which may be fine for graphics of this nature - have to see what can be squeezed out of it.
And do some more research into the Wave format - make notes for the next poor fool who has to determine which size buffer to scrape for each bit size / channel combo / formats that are supported etc. I also have alsactl on my list. neither of which are as cool as little numbers saying
[0-500]:000 [500-1k]:023 [1-1.5k]:123 [1.5-2k]:230 (etc times the bands)
That would make me a happy bunny. And the community I would venture too...

How about a link to the documentation on the method in use?
http://www.eetimes.com/design/embedd...low-power-MCUs
And an example of how to do it, with example C code?
http://processors.wiki.ti.com/index...._of_Real_Input
That one uses "float" and a TI dsp rather than the described above, scaled real number implementation.
Which is not so off-the-wall as it may at first seem, since the K3 has a (simple) VFP (vector floating point) processor - and the K4/K5 have the (much better) VFPv3.
That should give you food for though while you take a break to deal with "real life".
Hope you can find some more "hobby time", later this summer.
