tool for drawing spectral-analysis?

[Zoomby]

hi,

Is there a (free) tool with which you can edit a spectral-analysis of some sound with pens and brushes like an image in a graphics editor? So you could do some very precise filtering.

Firium kinda can. I don't think anything cheaper comes close.

-EDIT-
Check Firium's cousin, Eqium

You can't draw curves in Eqium. It's much more of a swiss army knife approach for EQ (and a very powerful one). Firium works well, and I think Voxengo also has a nice "draw the EQ curve" EQ.

hi,

I meant something else. I meant a spectral-view where you have two axis, one for frequency and one for time. The volume is drawn as different colors. Does this thing has a special name?
So this tool/editor don't has to be realtime.
It would be useful to edit single samples.

Elevayta's FreEq Boy does that too, and it's cheap, but I'm not sure about this spectral-palette drawing thing. It reminds me of something I found a while ago, I'll have a dig around..

--------------------------------edit
I remember 'painting' in an earlier demo version of WhiteNoise's DoppelMangler, but I haven't tried it recently..

--------------------------------edit
AdobeAudition has a SpectralView mode which gives us the ability to affect certain frequencies over time -ie isolate 10Khz to 12Khz and apply (your chosen effect) to the audio between those frequency ranges..

--------------------------------edit
When I said WhiteNoise's DoppelMangler, I actually meant his Additive synth. You can definitely draw/paint waveforms in there, the demo sounded cool - I think there was a patch building comp on yonks ago - but funds prevent me from buying it

It's called a spectograph iirc. You can work in spectrum mode in Adobe Audition for instance. Also, any kind of FFT filter/eq (if there is any) should do the trick.
