Hi, i'm looking for a few expert recording engineer sugguestions on how to possibly improve a guitar sound a bit. Firstly, i'll give a little background on my setup. I'm running three mics: One cardioid to isolate the sound, one condenser for a little bit of crispness and a tube in the room. I am happy with the initial sound i'm getting running two of these mics (one compressed) from a processor into two separate analog mixer channels and one mic directly(condenser) to a mixer channel. I then send all three of these mics out together bused (one line) as a stereo pair (L&R), compress again, then to an external converter and go optical into a single track into my multi-track software. My question is would I be better off running more than one stereo pair to my converters (separate for each mic) into my software, recording more than one track simultaniously? I'm wondering if i'll achieve a slight bit better edge on my sound somehow that way.. or perhaps I should also compress the other two mics and stick to running them all together as one line into a single track. Thx for any helpful sugguestions, opinions or info from any knowlegable engineers. ~Jp, "The Box", Minnesota, US

simply; dynamic range is the difference between loud and relative silence

if you subtract a frequency range from a signal, the difference between loud and soft IS DIFFERENT for those frequencies.

I can't make it any simpler...

there is linear, and there is non linear. EQ is linear, non linear items include compression, limiting.

Whoa, whoa guys. This is getting stupid again. Let's not forget the real issue at stake:

Are you sure you want to defend this, chunkybutt?

Hey Reggie-- I'm merely stating that dynamics CAN be affected by EQs (and getting shot at for it!). That is an important lesson for any engineer. You may be doing some subtractive EQing in a session, and then change your mind later and end up bringing up a load of noise. Know what I mean ?

(edit; spellllling)

Eq is a linear process, whether you want to use linear or non linear eq is not a concern. It is not dynamic dependent. if you boost 1k, it boosts 1k regardless of it's level or dynamics.

It's like a card trick. just because someone can make a jack turn into a queen, doesn't make them magical. if you take an eq and boost a frequency, and when something in the program hits that frequency and jumps out, doesn't mean it's non linear. the boost was always there, you just didn't notice it.

Michael,

you are mathematically correct but not exactly correct in terms of practicality (especially with analog EQs !). When you lower the gain of a frequency range, and then boost it back with a second stage, you are bringing up the noisefloor and thus dminishing your dynamic range.

Please try my previously listed experiment if you doubt this.

(1 shelf EQ -18db 5k -into- 1 shelf EQ +18db 5k= reduced dynamic range at the affected frequencies)

Or-- you don't even need to try it with an EQ if it's confusing-- with an analog mixer run one fader at -30db, and then into another channel boosting +30db on the line amp and see if the dynamic range is unaffected...

Reggie Mon, 10/10/2005 - 21:27

Yeah....I still don't see it. I mean, you can maybe affect the dynamic range by introducing noise with an EQ or pushing things down into the noisefloor; but where I come from, cutting frequencies is one thing, and affecting dynamics is another.

If you are trying to make a point about adding noise decreases your dynamic range, then well, that just is a pretty worthless point. Why even make a big fuss about it.

Reggie--

You already see exactly what I'm saying. I'm only saying that EQs CAN affect dynamic range.

How is this practical ? As I was saying earlier-- if you track a guitar and cut out 10db at 4k (for some reason...),, if you want to add that back later you will be raising the noise floor of the affected frequency range. This IS an important practical lesson for everyday recording and mixing.

All you are doing is displaying the inadequacies of your eq or your mixer, not that fact the the eq'ing process is not linear. a boost or cut is a linear boost or cut, it's not gain or dynamic dependent.

Okay, you are correct in terms of most digital plugins, and certainly the mathematics of what an EQ does. But as I said, this is rarely the case in practical terms, especially with an analog EQ. Many analog EQs will clip at certain levels of gain on certain bands, thus actually frequency-selectively limiting the signal. You may be suprised at how inaccurate the boosting and cutting is on many cherished vintage EQs... why they all sound different....

I am trying to help you avoid a situation where you subtractively EQ a floor tom (for example), but then find that you need to boost that frequency later for the mix. What you end up boosting is the noise floor due to loss of dynamic range at the affected frequencies.

You sir are obviously nowhere close to my genre of music, which requires alot more EQ'ing.... so if you find me "rediculous" then thats probably just the difference of the way you do things with the style of music you like (which i'm assuming is most likely african-american oriented). I sir, am high speed classical oriented with more distortion in one night than you use in an entire decade. SO, PISS OFF YOU ETHNIC MTV WUSSY!!!

Depending on the source, different formants occur at different points within the envelope. By boosting or cutting frequencies that do not exist across the entire envelope, EQ does have an impact on the perceived dynamics of said source. However, this impact is generally considered negligible on most sources. In my experience, this effect is indeed negligable with electric guitars except in the most extreme/obscene use of EQ. I suggest rethinking your guitar choice, playing technique, amplifier, pedals, microphone, and compressor prior to using EQ to create a worthwhile impact on the dynamic content.

Cheers,
Chris

No, what you are doing is adding phase shift and adding noise via the eq. You are not raising the initial noise floor, Nor are you affecting the dynamic range in relation to the original noise floor. the dynamic range is still the same relationship in that frequency.

Michael,

In the perfect digital situation, you are correct. In the real world analog realm... that is not the case. Please try this yourself with 2 analog eqs. The noise you are hearing is not phase shift, it is due to those frequencies being closer to the noise floor before being amplified again. From your description it seems you don't believe in noise floor.

Look at it this way; in the analog realm, if you lower the volume of a signal below unity you are decreasing it's dynamic range; the difference from loud to relative silence has diminished.

Michael Fossenkemper Mon, 10/10/2005 - 22:29

Again, you are hearing the noise induced by the device you are using. If you reduce a frequency, you are also reducing the noise floor of that frequency. The relationship stays the same. This is a linear process. If you take a stack of cards and raise or lower it in regards to height. the relationship of the bottom card is still the same to the top card no matter where you put it. If your EQ changes this relationship, there is something wrong with your eq or you are using it beyond the bounds of its ability or resolution. Don't mistake inability for fact.

That is absolutely not true in the analog realm. In analog gear, your fader or pot is (generally) connected to your source and your ground. A 'wiper' is moved back and forth from the source to the ground. The closer you get to ground, the lower the dynamic range is. When you try to boost that signal again, you are raising the noise floor.

In an analog EQ, the noise floor does NOT go down with the frequency-- it can not go down below the ground, which is connected to the ground of all of the other gear in your studio (hopefully,, if you've connected it all properly).

Again, you are mistaking inability as fact. The better the gear, the more ability.

Michael Fossenkemper wrote: Do you regularly eq things down to ground? When was the last time you had to cut a frequecy so far that you hit the noise floor of ground?

Every time you subtractively EQ, you bring the signal level of the selected frequencies closer to ground.

If you put that signal into another EQ and boost those frequencies back, you will be boosting noise because those frequencies were previously closer to ground and therefore the noisefloor.

I can't explain this anymore-- please re-read the earlier posts or other sources about this.

Sounds too artificial to me. Thanks again, but no thanks.

You're contradicting yourself yet again. Go team!

buttachunk, I hope what you're posting is just miscommunication. You seem like a smart enough fellow that I hope you'll re-read everyone's points and your own, and see if you still feel correct.

I've blown the mission several times with false reasoning, but whenever it's finally drilled into my head, I'll say, "CRAP! 10 pages later and you're right after all!" I'm a real @$$ sometimes when defending my incorrect point, which you have so far pretty much avoided, so kudos for that! I just hope you realize your error sooner than the 10 pages it sometimes takes me. ;)

JP-- after reading that hilarious quote about your metel (sic) sound, I know for sure now that you're not for real. :hihi: Cheers for at least restoring my faith in humanity. For a while there I was sure that you are actually serious, and I was getting worried.

JP defenders-- I do understand your perspective... it's always hard to see someone get mobbed, because it seems very unfair and a very unbalanced battle. However, I don't feel too much remorse because if you look at his posts, he initiated much of the abuse himself. Just because he's now been mobbed, does that excuse his attitude toward other people? So... I relate to how you feel, but come on now... he's no victim here. Besides that, he's not even for real. ;)

not sure exactly what you mean by that... don't know how I can be any clearer...

how about this;

http://en.wikipedia.org/wiki/Noise_floor

do you all understand that the noise floor of a piece of analog gear cannot be turned down below the noise of ground ?

you cannot use an analog EQ to EQ its own noise floor down, as has been suggested...... its noise floor is the sum of the noise generated by the ground and its internal parts (power supply, transistors/opamps/tubes). Ground is the lowest point-- it is the "bottom" of your fader. It doesn't get any lower than that, with the possible exception of an unconnected lead (which is rarely used in modern gear)...
