fft eq

[meatwalker]

hi i was wondering if there is such a piece of software as an fft equaliser that can remove partials in a certain range rather than simply attenuating them. if not, what interesting fft processing tools are available? i recently tried DtBlkF which was interesting, but most of the functions f**k the sound up pretty dramatically and r quite harsh - i was wondering if there was something with more sophisticated processing techniques and more precise controls

Try the Spectral EQ in Pluggo Junior

[st3pan0va]

you could try SP3CTR3 (caution: early alpha release).

not more sophisticated or more precise than DtBlkF - but it'll do a hard bandstop by removing all partials in a controllable range.

and then some other stuff that f**ks the sound up pretty dramatically.

damn.

Reafir, as included in REAPER does just this, i believe, and if i'm not mistaken it's just a vst, so should work in your host of choice

This is where Adobe Audition shines, more frequency mangling/eliminating tools than you could possibly ever need.

birrbits...what does this do to the surrounding material? I am familiar with frequency space editing, and would be interested to know how elegantly this works on complex material more than a small number of samples in width, as in the example above. I would normally expect such a removal to be quite audible. I assume there are more hooks available to fine tune and constrain the removal parameters.

not a thing, for instance I have removed a dog barking in the backround of a drum session with no audible clues.

I assume there are more hooks available to fine tune and constrain the removal parameters.

If by hooks you mean the shape, I'm afraid that you are limited to the rectangle shape BUT the great thing is that you aren't constrained to use this technique only for removal, you could apply any effect to the selected time/frequency area
(note that I have't figured out a way to make this useful yet, but it is pretty frikking cool).

This is from Magix Music Cleaning lab 10 deluxe:



I costs about 60 dollars (there are two new versions out)and it comes with a very good editor (not with the demo though) and a lot of great cleaning and mastering effects. A very underestimated program I think due to their "clean your records" marketing.

Check out the plug-ins at my site. Many of them use FFT processing to useful effect. Particularly Extra Boy Pro, Clone Boy, FreEq Boy....

P.S. Do not mistake the ROI functionality of Extra Boy Pro with that of Adobe Audition (or even Wavelab ). Extra Boy Pro is working in the spectral spatial domain. The others just work in the spectral domain - and not in real time.

The others just work in the spectral domain

could you please explain the difference between 'spectral spatial' and 'spectral' domain?

The 2D display you see on Extra Boy Pro has spatial domain (panning position) on the horizontal axis and frequency domain on the vertical axis. The others mentioned show a spectrograph, which is time on the horizontal axis and frequency domain on the vertical axis i.e. no spatial information.

When you draw an ROI in Extra Boy Pro this affects a defined range of frequencies at a define range of panning positions. When you draw an ROI in Audition this affects a defined range of frequencies for a defined duration.

Extra Boy Pro is working in real-time and so the time axis is represented by the changing 2D display.

Wouldn't it be better to be able to use a brush tool with a variable size for this sort of job? - you'd think Adobe of all companies would have thought of that?

omg audition is f**king sweet

Tapestrea is well worth checking out, for this sort of thing, as is Clam and Spear.
They are also free, which makes them well worth it in my book.


http://taps.cs.princeton.edu/ For Tapestrea.

http://clam.iua.upf.edu/screenshots.html For Clam.

I have'nt installed them yet(at the moment I'm cleaning up my hd), but they all look pretty exciting.
