Neil.

Is that also known as a Harmonic Equalizer?

I don't know, its called 'LinEQ' There are brodaband and narrowband versions, the broadband has more bands you can tweak. The manual calls it 'Linear Phase EQ'. I'd attach a screenshot here but I don't think I can!

Neil.

Yeah, I've actually used that EQ before. I have Nuendo 2 at home with all the Waves plug-ins, so no need to post the screenshot.

That's crazy two guys from London.

Am I a little late on this one?

Damn, neilius, I'd say our portraits, avatars, could be long lost brothers.

I'm in the UK's London, sndo is in Canada's London! That mohawk thing on my head isn't real by the way, its part of a mate's coat, I'm really as bald as a baby's bottom.

Agreed: Boosting EQ is best avoided. On the other hand, subtractive EQ can also carve giant holes out of the overall spectrum of sound. Multiband equalizers do not govern only their assigned frequencies. They are best viewed as a continuum of intersecting curves: By subtracting say, 250 Hz, you also attenuate adjacent frequencies. Too much of this nonsense can produce a hollow or lifeless mix.

If you're fighting feedback in a live setting, you'll often find the offending frequency and roll it off, only to hear the feedback migrate to a neighboring band on your EQ. Then you're stuck playing Whack-a-Mole, reducing overall volume and clarity in the monitors without addressing the root problem. Try to do more with less: Get the band to manage their stage volume and be sure that your monitors are actually pointed at their ears. There is no reason that even a loud rock band should not be able to hear their vocals in the monitors for the barest purpose of pitch reference.

studio's a different animal and all, but isn't the best way to avoid feedback (live situation) to make sure that your speakers have a very high sensitivity? that way you don't need to use as much gain to get your volume? thought i remembered hearing that once.

Make sure your mics don't point at the speakers, or position them as far away as possible. Feedback is usually a collection of sine waves so notch filters can be used to counter it with good success. Shure make an EQ device called the DFR (Digital Feedback Reducer). More info from: .http://www.shure.com/mixers/models/dfr11eq.asp. I got the chance to use one once and when I hit the button it scanned through all the problem frequencies and inserted notch filters automatically. Impressive stuff!
