Why You Should Use Metering Tools while Mixing and Mastering

Last AES convention I met a manufacturing rep for a very prestigious equipment company. He was demoing a piece of equipment for me, showing me all the great knobs and buttons that it had to offer. Then he said something along the lines of, “We don’t include a screen for these things since you’re supposed to mix with your ears.” That’s when I took my exit stage left. I think imposing a viewpoint like that is just plain wrong.
Obviously, you’re supposed to mix with your ears, but I don’t think looking at meters is going to destroy your mix.
I like visual EQs, where I can see how narrow my cuts are, and where I can visually sweep over the EQ spectrum. Similarly, I look at the gain reduction meter every time I compress something. It helps me get to where I want to go. There’s nothing wrong with looking at your plug-ins to see what you’re doing to the sound. Use it as an addition to your listening.
Don’t just mix visually without listening. That’s never going to work. Then everybody could have an amazing mix by just using those damned presets without changing a single thing.
No, use your ears, but don’t exclude helpful meters your plug-ins have to offer. They’re great when you’re starting out. They give you a handy visualization of what’s going on that’s especially helpful if your ears are inexperienced.
Enter the Meters
Logic’s multimeter is a great tool. It has a bunch of metering tools that you can take advantage of that work well for both mixing and mastering. Other audio programs all have some sort of meters that you can use.

I use the multimeter as a last resort when I can’t seem to figure out where the muddiness is. If the multimeter is clearly showing me an overabundance of a specific low end frequency (damn you 250 Hz!) then I’ll go back and try to cut that frequency from the usual suspects of low frequency instruments, such as bass, guitars, keyboards or drums. Many times it’s not actually the instruments themselves, but rather the reverb that’s muddying up the spectrum so I’ll go in and EQ the reverb to see if I can’t fix the mud.
RMS and Peak Level
When I master I tend to put the multimeter after all of the mastering plug-ins I’m using. It goes on after the EQ, Compression and the limiter. The reason I don’t just put it anywhere in the chain is because I need to know the final level of the song, and all those plug-ins will somehow alter the final level.
I use the limiter to make the song louder, and while I raise the level of the song I use the gain meter on the multimeter to tell me how loud the song is becoming. I try to aim for a level of around -12 to -9 dB, depending on the genre of the song. Therefore, watching the level meter closely while limiting gives me a really good idea of how loud the song will end up being.
You want a healthy dynamic range in your songs, and aiming for a dynamic range of around DR10 is a pretty good starting point.
Goniometer
I use the goniometer rarely, but I check it at least once while I’m mastering. The goniometer is sort of a phase meter. It tells you if your track has any phase problems. If the track stays somewhat in the middle, with no parts creating any weirdness you should be fine.
Another way to check is the correlation meter below. If the meter is close to all the way to the right, you shouldn’t be having any phase problems.

The reason I say I use the goniometer more while mastering rather than mixing is that while I’m mixing, I’d rather flip the output to mono and listen that way instead of relying on the meter. Since I’m mixing I’ll have more control over the individual elements of the mix. So if I flip the song into mono and something just vanishes from the mix, I know I have some phase problems. And since I’m mixing, I can go back to that instrument and fix it right then and there.
But if you’re mastering, you have less control over all the elements of the mix, and you’re almost screwed if the track you’re mastering has massive phase problems, since you can’t go back and fix it.
EQ and Compression
The gain reduction meter on your compressor is an invaluable tool when you’re compressing. It tells you by how much your compressor is compressing the signal, and you can easily see the attack and release times by looking at the meter.
A very useful thing when you’re trying to time your compressor to the beat of the track. And since it tells you how much you are compressing, it’s a handy way of knowing how much makeup gain you need to apply so that you’re at the same level as before you started compressing.
Similarly to the multimeter above, some EQs have frequency analyzers that show you what the signal looks like. In Logic you just press the button on the Channel EQ and it gives you a visual approximation of the frequencies of that signal. It can come quite in handy when your ears aren’t trained enough to hear where problematic frequencies are located.

Conclusion
Metering is a great way to visually see what the audio is doing. Slapping a multimeter and checking the frequency range of a multi-track is a great way to see if your mix has an overabundance of some frequency or other. Making your track loud but dynamic is also a priority in these days of over-compressed masters, so you have to know how hard you’re pushing your limiter and how loud you’re making your mix.
How do you use meters while mixing or mastering?

Sorry everyone. I’m not sure why comments were closed on this page for a while, but the issue is now resolved. Comment away!
There are two schools – some say “only mix with your ears” and the others say “no, I wanna see graphically what`s going on”.
I think both are right – the best way is to mix with ears and eyes simultaneously and then you should sometimes close your eyes to listen to the sound only. And maybe several times you should even close your ears, because with a break you can perceive better what suits for your track and what not.
That’s a great comment. I think you should use all the resources at your disposal, but also take breaks to rest your ears.
What is your favorite tools (vst format) for metering ? Blue cats bundle is a good one.Also i heard some good reviews about Nugen Audio
I just use the multimeter in Logic. It works well enough for me so I haven’t looked at other alternatives.
Great article.
Seems to be a typo though. Either that or are you collecting good mix engineers Björgvin? :-)
“If the track stays somewhat in the middle, with no parts creating any weirdness you should be mine.”
That’s hilarious. Thanks for pointing it out, Simon – are you volunteering? ;) I changed “mine” to “fine”.
They’re all MINE!!!!
Thanks for pointing that out ;)
“I try to aim for a level of around -12 to -9 dB …”
Are you talking about RMS level here, where you want the average level to be around -12/-9db?
“You want a healthy dynamic range in your songs, and aiming for a dynamic range of around DR10 is a pretty good starting point.”
Are you calculating this DR by the Peak – RMS? How do you calculate the DR?
PS: Great article!
Hi Dustin, thanks for pointing that out. Yes, I’m talking about RMS levels here. A peak of -12 would be really quiet, but an RMS level of -9 is loud enough. I measure with the multimeter by just looking at the meters at the loudest part of the song, if it’s hovering around -10 I usually don’t worry too much.
I find that most of my rock albums in my collection are around -7 to -5 RMS. They also clip just a little. Is that just the genre? Also is there an RMS limiter out there?
That’s the problem with a lot of genres, they’re trying to be loud when they don’t have to be. Ian Shepherd of Productionadvice.co.uk is the man behind Dynamic Range day, and the war against loudness. You don’t need to be loud to sound better. It’s usually the reverse.
There is also the Pleasurize Music Foundation which works against the loudness war, too. They have a great plug-in named Dynamic Range Meter available for download that shows the dynamic range of the track, the RMS and the peaks.
Maybe there should be a organization against frequency fill-up, too, could be called Space Agency or so. More and more songs have the whole frequency spectrum filled to the full which is very fatiguing for the ears. Sometimes less is more, but that´s another subject, I don´t wanna go off-topic…
interesting. In my music I look to fill the spectrum as a goal. Well fill the spectrum isn’t the real goal. It’s more like making sure there is contrast in the frequency spectrum. Keeping the lows low and the highs high. Is this something I should avoid?
Yeah I don’t know about that. I think every frequency should be represented in a song. Everything should be balanced of course, but a full mix needs to have a full sound which is usually done when certain instruments fill up each of their respective frequency areas. Too much EQ on the high mids can certainly cause fatigue to the ears, but a mix should definitely have all frequencies present and balanced.
I´ve meant that a good mix need to breath like a human beeing. The frequency spectrum obviously needs to be filled, but not to the extreme. The risk is to put so much content in a song that it sounds like a vacuum cleaner, especially the midrange-mixture of piano and e-guitar…
I downloaded the free dynamic range meter from http://www.dynamicrange.de/ and it works great. It shows peak level, RMS level and dynamic range, all in real time and with incredibly fluid graphics. Maid in part by the outstanding company, Brainworx. There’s a big push to end the “loudness wars” and I’m all for it!
