A Sarcastic Statement
Hi there,
I just finished doing a first mix down of a song that my band recorded in my studio. I've been working on it and have done all the mixing to a point where all of the effects, pans, eq's, compression and volume levels are all satisfactory. I sent to the band and they're all happy to proceed with mastering. When I look as the master bus with a frequency spectrum analyser it looks something similar to this: freq spectrum.webp. Sorry I don't have a screen shot since I'm not at home. But what it is is a little more build up of the low end and the high end being light.

When I listen to the mix in the studio or anywhere else, everything is translating well and nothing sounds bad, frequency wise. Each element sounds good on it's own and in the mix and the whole mix sounds pretty balanced. Of course, mastering will help give it that final polish, but the highs, mid and lows sound good to my ears. It's not too dull or overly bright imo.

So my question is, what should I do to fix that issue I see on the graph? Even though it sounds decent, I feel that it should be pretty even all the way across. I plan on doing quick and dirty mastering on my own for each individual song, until they're all done, then we'll get them professionally mastered some day. Some of you will maybe say use a multi-band compressor and some eq to adjust the overall mix. Some will say to go into the mix and adjust the levels there. So in this case, it'd be make the highs on everything higher in db's and the lows on everything lower in db's. My issue is, everything is pretty rolled off in the low end. Some stuff at 60, some at 80, some at 220, etc. The ONLY things that don't have a semi-aggressive roll off are the bass guitar (hell even that is rolled to 50) and the kick drum. Most of the stuff has a roll off slope of anywhere from -6 octave all the way up to -24 octave. I wanted to preserve SOME low end in some of the tracks like rhythm guits and the like, so I gave those ones less steep of a slope. So maybe I should make the slope as steep as it goes for every track other than the bass and kick? Seems drastic.

So if I went in to adjust the bass guitar and kick to have less bass freq's they would sound too thin imo. I want them to occupy the low end. If I go and turn up the highs on all the tracks that are intended to have good healthy highs, they get too trebly each on their own. So to me, eq'ing the whole mix sounds like a better strategy so I'm not making drastic adjustments on every single track to make the graph look better and potentially changes the way the individual instruments sound.

Some may say if it sounds fine, leave it. So I would, but the main concern i am saying/asking all this is because when i listen to it in the car with the bass up to a healthy level or cranked on soundcloud with headphones (soundcloud compresses it quite a bit) the floor tom and kick drum are distorting the speakers a bit in the low end. It's not the waveform that's distorted, I think it's just that low frequency build up from all the tracks at once causing that.

What should I do? Fix it in mix and risk having a thin kick and bass guitar? Adjust the whole wave with eq and mulitband compression? Make the roll off slopes of everything steeper? etc..

Maybe this belongs in the mixing thread (?), but hopefully you can help. Thanks!

Don't use your eyes to judge sound. Use the graph to pinpoint problems you hear, but if you don't hear a problem don't even look at the graph.
 
Thanks for the speedy reply! :D

Right, I agree, but what about this part...

I wouldn't try to fix the way it rolls off toward the high end. That's normal. But the bump in the lows seems to correspond to the problem you're having so it may be worth fixing it. I would bet your monitoring setup isn't giving you accurate info on that range (about 45Hz to 120Hz) and you're mixing in too much of it. Maybe some well placed bass traps would help.

The room is trapped well. Usually untreated bass in a room will sound louder, so if anything I'm having the opposite. I blame that on my monitors with only 5" woofers (I plan to buy 8" soon and upgrade). But I do A/B back and forth to, believe it or not, a Logitech computer speaker kit. It has the two desk top standard speakers and then a sub woofer. I keep the woofer's level pretty low, but when i crank those speakers it gets some good low end. So I use that to test bassiness - if the sub doesn't have the bass guitar in it for example, I know there isn't enough bass mixed into the bass guitar. If the kick doesn't thump in my chest, it doesn't have the low end I need, etc.

So all that being said, even with the sub on, everything sounds balanced. When you say it might be worth fixing it (the lows an the graph corresponding to my problem) how might you suggest doing it? That's my original blunder of my post.
 
I think even with your two systems and bass traps there's something about your monitoring situation that's misrepresenting your mix in a way that makes you mix in a bit too much 45-120. Perhaps the bass traps aren't where they need to be or don't go low enough to help.
 
Usually untreated bass in a room will sound louder.

Not really true. An un-treated room can have a lot of nulls, too. And if that's where someone happens to be sitting, they're going to crank the bass. Sort of besides the point from the main topic here, but I just thought I'd mention that.
 
My most effective solution would be to copy the stereo track twice in your DAW. Keep the original if this fix doesn't work!
Notch-filter the offending frequencies in one stereo pair, and isolate the area in question in the other stereo pair with high- and low-pass filters. Give the low-mids some light compression. Bring in the low-mids, and see if they balance out better.
 
Can I ask a question? Have you looked at a graph of similar commercial music in the same genre? Stuff you like? I used to look at graphs of commercial mixes in an analyzer and lots of them have a bump in this range as that's where a lot of the whomp lives for the kick and bass. I mean no one really is expecting a flat graph here right with equal energy across the entire freq spectrum?!?!
 
pps - the whole idea that there is something wrong with it without anyone actually hearing it is weird, unless I missed a link, in which case I am an idiot.
 
Here's a graph from a The The tune off the album Dusk. This tune has a nice whomping low end. You can check out the original on the utube. Note the bump. Guess what this track does in my car stereo if I turn it up to loud? The low end farts.....

Spec.webp
 
Exactly. It's totally normal to have a bump in the low end. Do you realize how much more energy bass takes up than treble frequencies. Nobody's expecting the graph to be a straight line across, I hope?

Yeah - that's what I was wondering?!?. The OP posted a graph (although from memory) of a pretty normal looking mix curve. Said the mix sounded great, but asked how to correct the problem. Also said it distorts a little in the car when cranked. The graph looks like just about everything in my music collection, and my cars do exactly the same thing when cranked. *And* no link posted so we could actually check it out. I just think people massively overthink this stuff.
 
It would be worth trying other music on the systems in question and trying the mix on other known systems until you can separate mix issues from system issues.

Thanks for the comments guys...
Yep dead on to how my mix looks. To be honest, I've always just "used my ears" and only recently started using the graph tools like this. I basically used it as a final check before mastering and after hearing everything to my satisfaction other than kick drum and floor tom overwhelming thump in car or cranked in headphones. Looking at the bass guitar track alone with the freq analyzer, it is the one causing this thump. It has the thump at same level (even though I have the dual-bass-track bus notching out about -10 dB in that area due to it being an overly resonant frequency originally causing "bass headache" syndrome).

I am going to post this link with the hopes you'll cut me some slack here...SINCE I HAVE UPLOADED THIS MIX, I have made some subtle adjustments to the following so keep that in mind to ignore these issues you may perceive:

- Lowered the lower freq harmonics in the toms and snare very slightly (they were just a tad too beefy in low mids you'll notice), although I did desire a good beefy, exaggerated almost 80's drum sound (hence the snare verb you'll hear)
- Lowered the kick boost in low end by around 1dB
- Raised synths up about 1db
- Raised piano up abot 1dB
- Lowered Right Drum Overhead about 2 dB (somehow I think I accidentally nudged up that fader right before mixing it down. oops)
- Lowered volume on high tom in the first verse by about 2dB
- Raised floor tom track in 1st verse by about 1dB
- Lowered the phasey effect a little on the drum loop thing before 1st chorus.
- Added some minor harmonic distortion to the bass track for a slightly sweeter tone

Listening to it keeping in mind that I have, since this upload, made the above changes, what do you think - pertaining to my issue? I'll post it in mp3 clinic for other comments later on. PS: Please don't share this link anywhere, it's a private link, so to speak. What happens in HR stays in HR! :)

Disclaimer: I DID NOT record or mix any of the other songs on our Soundcloud. These were done elsewhere, hence my reason for wanting to do it all myself rather than paying money for complete garbage. FFW about 45 secs, sorry.

The toms are painful to listen to and they smother the mix. The snare is still a bit too fat and loud, and the bass guitar is almost nonexistent.

Sounds boxy in the low mids to me. The lows aren't really low enough. It's like you rolled off everything. Like there's nothing happening below 120hz or something. Kick and bass have no power. I suggest you stop worrying about frequency analyzers and start using your ears more. I think maybe you overcooked, over-EQ'd, and over analyzed it. :o
 
Here's an example of what mine typically look like just as an example.....while my mixes aren't the end-all-be-all perfection, they translate very well on various systems like the car, MP3 player, home stereo, studio monitors, boombox, etc. They never distort or overload anything when cranked. This is one I was working on today.

Hey Greg - I'm not one to argue with your success. I was pointing out that a number of commercial cds I own have a similar curve and DO fart out my cheap car stereo when I crank them. Typically this is material with a significantly more low end than your mixes, in an entirely different genre. I suggested that the guy post his stuff as a way to use ears to solve the problem.
 
Yeah I didn't post that as a gold standard or anything. That's just how mine come in. I actually never look at that graph thing. This thread piqued my interest so I checked one out.
