There's something wrong there. A spectrum with 65000 points would
never look like this. Can you reproduce this and are you absolutely
sure that you selected 65000??
Well, the spectrum is cut off at about 20'000 Hz. Anything beyond that
is zero. The only reason why you see it is because you choose to do
so.... There is no bug here but maybe some misinterpretation of how a
spectrum analysis works. What exactly are you trying to achieve?
Regards,
Perhaps not a bug, but the zoom of the Spectrum window is not very intuitive to use. Once you have zoomed in, it's very hard to zoom out to a view which I - and obviously also Babak - would expect.
Possibly there's a window redraw bug...? The issue has something to do with the horizontal scroll bar and its position as well as with the size of the window. It probably shouldn't zoom out more than the highest available frequency.
Anyway, after some experimenting I guess I figured out the trick how to zoom out while getting rid of the unnecessary frequency scale...
What I want to achieve is to analyze, whether low frequencies are present in the sound file, especially those below 100 or 50 Hz, respectively.
I am shure, I chose 65000 in the setting.
With that setting the only correlation I see is that the frequency range besomes much large, up to some 100 kHz, as can be seen on the screen shots.

That's bizarre. In principle, choosing a larger number of samples does
improve the resolution at low frequencies, so this is what you should
be doing. Now when I use the settings shown in
A follow-up on this one. I think that the problem was caused by a
mistake in the German translation, this is why I couldn't reproduce it
earlier. I just updated the German locale in the archives on my
website, so if you download it again it should work now. Cheers,
