E.Q. Frequency chart needed!!

[ulrichburke]

Dear Anyone.

Got an E.Q. plug-in from the Audacity plugin page. It looks great. You enter the frequency you're using, slide the sliders and get a perfect E.Q. job. Onlly one, rather huge, problem.

How the heck do you KNOW what frequency you want to E.Q.? You import your soundfile. There's no scale of frequencies that I can see anywhere (if there is, or if there's a plug-in anyone knows that gives you a scale of frequencies, Please tell me!) As there's no scale of frequencies, you're working entirely by guess work. You might hit the right number sometime this side of next Christmas, by luck. Or you might not. Probably the latter.

How do you find out what frequency you're trying to E.Q.? Logic - only works on Applemacs, darn it! - gets round the problem by having a line of light with a bump in it. You slide the bump about until the sound 'sounds right'. Nice and - er - Logical! Please, if anyone knows how to work out what the frequency IS you want to change, can you tell me?

Yours hopefully

Which plug-in is it?

the plug-in I was talking about was this one

Equalization

from the list on the downloads page (that's all it's called, honest!) It's the 38th one from the top on the list. The same guy, I've only just noticed, has done a 10-band equalizer. I'm just about to downlload it'n' take it for a spin, see if it stops me having to use my brane as much to get EQ right (Oh, the pain of having to think. Oh, the pain of it all....!!)

Thanks for the very, very interesting 'heads up' on the Analyze function in Audacity. Not only did it show me what that did, I'd never have thought of that by myself, but it indirectly showed me a fascinating website for the disabled (the link's on the same page!) which, being disabled myself, proved most interesting perusing.

Yours respectfully

Could you post the URL of that page? I think I know the one you are talking about, but I can't find it now.

Thanks.

Dear Bill

The URL of the page from where I obtained the download (the 38th one from the top, remember?) is as follows:-

The technical name for this effect would be: "Semi-parametric equalizer with optional normalisation".
("noramalization" in some parts of the world).

In the Spectrum Analizer, you may see a peak, (or trough) that you want to adjust so as to achieve a more even frequency response. This effect would be a good tool for the job - you would just "tune in" the peak/trough centre frequency and boost/cut as required.
