Spectral Analyser Questions

mehmethand

Hi,
1- Is there a way to make Spectral Analyser to show data for more than 32768 samples? (I want to make it slower.)
2- Is there a way to make it peak hold?
3- is there a way to change the dB range?
4- is there a way to tilt it?

Regards...

@mehmethand ahah that’s all I’d like to have too especially for the upcoming release :) but that might be too much too ask… maybe having a larger window is doable, I’ll try to have a look tomorrow if I could find in the source…

mehmethand

@ustk Thank you so much. I also checked the source code but I couldn't find anything. I'm sure many of the answers are hidden there.

ustk

@mehmethand The truth about the universe is there, somewhere deep inside the source code…

ustk

@mehmethand Oh yeah I forgot that one to add to the bug list... Changing the buffer size breaks the analyser until you reopen the project.
It would be good to have the buffer size setting on the fft node too, as well as a time average setting, and/or max display mode. Well, after the bugs are fixed...

ustk

So I can add more buffer sizes, (at 131072 my processor begins to slow down...) but the reaction of the analyser is kind of cool.

I found a second bug: it is impossible to access the Buffer Size from the script (although the Preview Type works)

ulrik

@ustk To change the buffer size via script you use the actual buffer size in the script like

inline function onBufferSizeControl(component, value)
{
	local sizes = [4096, 8192, 16384, 32768];
	
	Analyser1.setAttribute(Analyser1.BufferSize, sizes[value]);
};

@ulrik oh thanks I didn't know that! I was using the cb value…

ulrik

@ustk It's more cumbersome to change the preview type I think, and it's a bit flaky

@ulrik Thanks for your help, Is there a way to change the dB range also?

ulrik

@mehmethand I don't know about that, sorry!

ulrik

@ustk said in Spectral Analyser Questions:

(although the Preview Type works)

Yes the module will change but not an attached FloatingTile, at least not for me, I have to change the "index" in the "setPropertiesFromJSON"...

ustk

@mehmethand That is not currently possible

@ulrik yes changing the floating tile data is a bit harder. But I generally don't want all types. You can also create 3 tiles and just show the one you want
