Subtractive EQ Program EQ is used to compensate for non-linearities in the system's frequency response so that specific frequencies will be neither over- nor under-emphasized. The result is improved gain-before-feedback, higher intelligibility and reduced listener fatigue. The concept of subtractive EQ is simple: reduce the frequencies that are offending, rather than boost those that are lower in the mix. This is most often done with a graphic EQ, but sometimes a parametric EQ may be used to provide a more precise correction of response problems. Subtractive EQ generally results in lower noise and greater headroom than that obtained by boosting some frequencies while attenuating others. |
This applies to live PA system situation not studio production hence 'removing feedback'
You shouldn't have to use this method to remove cable noise as you will be killing off particular frequencies of your synths while you're recording them, which you don't want.
If your cables are that noisy you should look at fixing the noise where is comes from (the cables) not eq ing. Maybe you need extra shielded, separate audio cable from power cable, different cable altogether...
good luck |

| There are plenty of places that say you should use subtractive eq in the studio. But I cant find a place that will teach me how to do it. It's not just about the noise. It's also a better type of eq. It sounds better. |

There is no 'should' in the studio, so cut that out right away.
However, in some studios it is common practice to use the subtractive method.
Which is basically to say,for example, rather than boosting the mid pot by 3 dB, try cutting the bass and treble pot by -3dB to give exactly the same sound and correction- but at the same time leaving you more headroom as you arent increasing the level of any parts of the spectrum.
However, some people go and whack the fader up after they have done this anyway, thereby completely over-riding any benefit you just had from using this method. :stongue:
Has not got a lot to do with noise really- its all about the headroom.
Subtractive eq='cut don't boost'
Was it really to much trouble to work out from a dictionary what 'SUBTRACTive means????? |

| Subtractive EQ results in less phase shifts in a waveform. THAT, is the only real benefit of subtractive EQ. |
|
|
| Rob |
| Also building on that point, when using additive EQ'ing you'll get alot of phase shifts/comb filtering occuring (I used to when I was EQ'ing kicks). Let's say we boost a give frequency, and then bam: A tiny pop or click suddently appears from nowhere from a phase shift. |

| The only phase shifts, clicks, or other artifacts I've ever had from EQing was with the Fruityloops EQs. With any half-decent digital *or* analog EQ there should be no difference between positive gain and negative gain (except for the volume). |

Like I said...I know what subtractive eq is...I just don't know how to do it.
I know what video game design is as well..But that doesn't mean I can make video games.
I simply would like to learn how to eq this way for all the elements in my track. Can you help me with any links that will teach me how? Thanks!!! |

see eq more as an art than just knowledge.. it's something you won't learn in some weeks.. and subtractive eq won't won't change that.. |

| I never gave a timeframe that I must learn how to do this in. I just asked to to be given the means so that I can study this for the rest of my life if that's how long it's going to take. |

| Thank you man! Appreciate it:) |

Yes I can agree with u on that 100 %!
By looking for technical terms such as subtractive eqing wont help u learn how to eq u just making ur understanding more complicated and ur learning curve steeper.
What I don’t understand is how one compares the quality of equalizers?
Understanding factors such as phase shift, phase correction ECT... how does one actually know that an eq is of a high quality ? :conf:
I use cuabse sx 2.0 equalizer and it sounds great no problems with it even if I don’t fully understand equalizers like I’m suppose to but hey i never said i did.Anyway I had a "15 day trial" of the wave’s audio processes but I only used the C1 compressor.
The waves pack equalizers must have more to it then the standard equalizers one finds in other audio processors Right?
