I gave 1.0.3 for Windows a set of 125 ksps Perseus files and it still crashes on FFT size of 16M & 32M.

Ack yes. I was able to make it crash with 16M and 32M FFTs.  I've made some more changes, and now it is not crashing, so version 1.0.4 is now available for download. We'll eventually get this working  ;D

skeezix:
With 1.0.4 on Windows, I fed it Perseus files at 16M & 32M FFT and it processed them fine.

Do have a question about the display, the higher the FFT, the less vertical it becomes. Is that expected?

Yes. Each line on the waterfall is the output of one FFT. So as you double the FFT length, you end up with half as many of them, so the waterfall is half as tall.

I could add an option to take multiple FFTs with the same data, sliding a window along the data, so the waterfall would be longer. You'd be re-using the same data across multiple FFTs, but it still might be useful. I've been considering adding this anyway, maybe that's a good idea for the next release?  Hey, your CPU isn't warm enough, let me fix that for you  ;D

Using a large air-cooler on the CPU now and it can handle Crysis, barely.
