Message: [QUOTE="Scorpio, post: 15801, member: 4"] I agree with [USER=3]@Black Panther[/USER] that iZotope's Vintage EQ isn't that versatile and the same applies to pretty much every single Pultec EQP-1A and Pultec MEQ-5 clone out there on the market albeit the major difference being that iZotope's Vintage EQ is best suited for audio mastering because it's without a doubt pristine clean and that's what you need. In contrast, you don't want to use something that adds weird noises and changes the sound even when all the dials are flat however for mixing music you can get away with that as long as you take a minimal approach without overdoing it. [HR][/HR] Anyways, let's start with the low-end. Suppose you want to boost the bottom-end of your program material, podcast, music whatever. Well, you could simply use a simple first-order filter at 200 Hz with perhaps a gain of 2 dB. Unfortunately, doing so means you will slightly increase the gain of other surrounding frequencies extending to about 450 Hz somewhere there. But what if you don't want that extended boost of the mids? Now, this is where the low-end trick technique of boosting and cutting with a Pultec comes into play. You can do that with Vintage EQ but before I go there you first have to comprehend the following settings i.e. especially in the context of audio mastering with Ozone Vintage EQ: [TABLE] [TR] [TH]Generic EQ "gain" (first-order filter)[/TH] [TH]Vintage EQ "gain" (bottom)[/TH] [/TR] [TR] [TD]2 dB[/TD] [TD]1.27355 dB (i.e. low boost only)[/TD] [/TR] [/TABLE] Note: I don't think it's necessary to exceed 2 dB for mastering (if it comes to that then just use the standard Ozone EQ). Therefore always remember the magick number for Vintage EQ it's 1.27355 dB, don't use anything else other than that because the slope changes. [TABLE] [TR] [TH]Generic EQ "freq" (first-order filter)[/TH] [TH]Vintage EQ "freq" (bottom)[/TH] [/TR] [TR] [TD]350 Hz (F4, +4 cents)[/TD] [TD]20 (i.e. low boost only & assuming target gain is 2 dB)[/TD] [/TR] [TR] [TD]750 Hz (F#5, +23 cents)[/TD] [TD]30 (i.e. low boost only & assuming target gain is 2 dB)[/TD] [/TR] [TR] [TD]1170 Hz (D6, -07 cents)[/TD] [TD]45 (i.e. low boost only & assuming target gain is 2 dB)[/TD] [/TR] [TR] [TD]1600 Hz (G6, +35 cents)[/TD] [TD]60 (i.e. low boost only & assuming target gain is 2 dB)[/TD] [/TR] [TR] [TD]2300 Hz (D7, -37 cents)[/TD] [TD]100 (i.e. low boost only & assuming target gain is 2 dB)[/TD] [/TR] [/TABLE] [B]Note:[/B] You have to completely disregard center frequencies such as 30, 45, 60, and 100 Hz because, particularly for mastering music, they are not useful--they are terrible. Therefore, the ideal setting here is always 20 Hz anything else is wrong, LMAO. [HR][/HR] Since y'all now understand that a bottom lift on Vintage EQ can extend up to 2300 Hz, it should be pretty clear that this is not worthwhile, as I have already said. Why would someone want to do that on a mix, I wonder? So, for the ultimate Vintage EQ setting, I'd recommend y'all try the following: [TABLE] [TR] [TH]Freq[/TH] [TH]Low Boost[/TH] [TH]Low Cut[/TH] [/TR] [TR] [TD]20[/TD] [TD]2 dB[/TD] [TD]0.3 dB[/TD] [/TR] [TR] [TD]20[/TD] [TD]2 dB[/TD] [TD]0.5 dB[/TD] [/TR] [/TABLE] The result is similar to a first-order filter at 200 Hz with 2 dB gain and -1 dB attenuation at 380 Hz with a bell curve nicely set to Q 0.510 (BW 2 ½ octave). Alternatively, you could use either Q 0.555718 or Q 0.580547, but the ideal quality factor here is Q 0.510. For interest's sake, Q 0.510 = Q 0.722 on FabFilter Pro-Q, and also, I don't know if this has anything to do with the subject at hand, but most three-way ATC Loudspeakers have their crossover frequency set to 380 Hz. Yeah, I know that's random. By the way, and on a more serious note don't forget to sauce it up with a first-order shelf set to 2K with either 1.5 dB or 2 dB gain, of course, why not? [/QUOTE]
