Filtering vocals - High Pass and Low Pass

(This is an embellishment on a post I did on gearslutz.com)



Like many engineers, I put a High Pass filter on my vocals when I’m mixing. Usually from 100hz to 150hz. (A little higher with female vocals.)
I do this because for the most part there really isn’t much down there that is useful or going to be heard in the mix (before I get any haters, let me say that if I were mixing a vocal and acoustic guitar only or a solo vocal than maybe I might approach this differently. I am mostly talking about dense mixes and production).


I do the filtering pre-compression so that any low frequencies won’t pump the compressor. This filtering will really clear up the mix a lot. For that matter I do a lot of high pass filtering on other sounds too, because low end is weird in that a tiny tiny amount of it can really screw up a mix. Even stuff you can’t hear will mess with a mix.



But here is something else I do that I think is a little unusual: I often put a low pass filter on vocals as well, most of the time using a McDSP plugin called Filterbank (F2 configuration).

I usually do this on backing vocals or on ‘adlib’ tracks in hip hop. Usually I’m taking out everything above 10khz and even as low down as 6.5khz.
I’ve found that sometimes the vocals just get so harsh and I’m putting de-essers on all the vocals, so might as well take a short cut. It’s also because so many times when I’m mixing for clients it sounds like all the vocals were recorded using the same mic with the same settings. It’s kinda hard to to get a good blend sometimes when all the vocal stacks sound the same.


I read an article about how Michael Jackson recorded his vocals. He would do his leads on a condenser mic and back-ups or stacks on a dynamic (in the article they said a Sure SM7). I think the point is to switch up the source; it gives a bigger sound. So when I’m mixing I’m trying to achieve the same thing with the tracks that are sent to me.

Here’s something else I noticed while mixing. I would often get a nice natural sounding vocal and then in one part of the song want to get that 'telephone' filtered effect. I would always be surprised that after doing that that the natural sounding vocal just sounded boring. It made me start filtering the lows out of my vocals more and being a little more extreme in my approach. I also sometimes go halfway into that telephone type sound for my leads, even boosting the mid-range on my vocals. Remember, all sound systems sound different and you can never really be sure how your mix is gonna sound. But you can be sure that all sound systems do have mid-range and your vocals will be heard there if you treat mid-range as your friend.

I hope this helps.

Identity Crisis

I’ve been thinking lately about identity. More specifically, an artist's identity or lack thereof. I think many artists have an identity crisis going on and they don’t even know it. What they think they are is often what they are not. And this is very important when we are all trying to be on the same page as far as production and mixing goes, because it all eventually ends up in how you are marketing your music. This is one of THE biggest problems I run into with new artists.

Let me use some examples to illustrate:
I had a band a few years ago that I needed to produce a few songs for. On their rough demo cd there was this one song they'd added as an afterthought that was actually the best song in the batch. It was a mid-tempo rock ballad. Out of the 4 songs we ended up recording, that song came out the best and got the band a lot of attention. Everyone I sent it to lost their minds (even to this day if that song is on a producer reel I give someone, the first question from the listener is “Who is that?”). At the time we did these songs Creed had kind of dropped of the charts and Nickelback hadn’t hit yet. I explained to the band that there was a hole in popular music for that big ‘fake’ metal rock stuff (I didn’t quite use those terms with them but that IS what it is) and that they could fill it. They had the sound, the singer had the voice, the timing was right and the interest was there.

The problem was that the band thought of themselves as a technical rock band more along the lines of System of a Down. They had NO songs that came close to sounding like that, and the few that were technical were very weak in the actual songwriting department and weren’t even interesting in the technical department either. (The singer had some pipes, but the musicianship was very weak - another misconception in the band). What they did really well and what they sounded like was the big Creed/Nickelback thing. I couldn’t convince them to do more songs like that, and in spite of the attention the ballad was getting they wouldn’t even play it at all of the gigs! Needless to say they toiled for a few more years, actually got an indie deal and recorded another album of misdirected songs (without using any producer) and they went nowhere.

Sometimes a band needs to step away from their egos and realistically look back on what they are doing, question their assumptions about themselves AND listen to the advice of their elders.

Here is another example: I was mixing for a band and the music was kind of a pop/rock mishmash. Not recorded or produced very well, which always makes mixing so much harder. They kept bugging me to put weird effects on things that seemed incredibly inappropriate for the songs and was making everything sound worse and ridiculous. I kept asking them to explain what they were going for and was told “We want to sound like the Beatles”. Man.... how could they be more off? I had to explain that I was not a magician. If they wanted to sound like the Beatles they needed to write songs that sounded like the Beatles first, and then record and produce songs as well as the Beatles did. How could they have gotten all the way to mixing and not realized this?

More recently I was at a rehearsal for a band I’ll be working with soon that has a very powerful modern commercial rock sound. They're a very good band, have great songs and the singer can belt (very Jeff Buckley-like). During a break the singer says he wants the drums to sound very garage band or maybe like Hendrix or Led Zeppelin and explains that he has spent a lot of time playing blues and old school rock. Now I LOVE those bands, but what he doesn’t recognize is that he has grown up in the modern age and IS a product of now. I think what he really wants to do is pay homage to the legends, which is honorable, but not a true representation of what he actually IS.

This project is in it’s early stages and I have yet to see what will happen. It is very difficult to make young artists see that what they grew up listening to and dreaming about becoming is not usually realistic because the times, sounds and music business have changed and, most importantly, you must find your own voice, your true voice, to speak through.
- Do you really know what you’re best at?
- Can you accurately identify the things that are connecting with your listeners?
- Are you trying to be your favorite band from your childhood or are you trying to be what you should sound like in 3 years?

Be honest with yourself. I’m not saying don't reach and stretch who you are, but do sit back and try to be objective. Be real about the things that ARE working and have worked. Stick with what you are good at.

Mix Compression: Two Approaches

I was on gearslutz.com and came across a very heated discussion about mixing compression on the mix bus. Someone had made a comment about not using it and it went on and on about whether you should, how you should use it, what gear or plugins you should use, and so on. I really don’t want to get into all that right now, but I will re-post what I posted on gearslutz here:

There is no one answer to whether you should use compression on your mix buss or not. Everyone has a different approach and I have gone through my own phases where I did or didn’t compress the mix. (Presently I’m off it, but I do happily compress about everything else and I’m using a slight limiter on the mix.)

I once had the honor of moderating a panel for NARAS that had Brendan O'Brien and Jimmy Douglass on it. What a treat! I threw away the questions that had been prepared for me and asked all the things I had heard rumors about and wondered myself for years. One of these was about mix compression. When asked what each of them used on their mixes Jimmy's answer was "None", Brendan's was "YES! Lots! Sometimes 2 or 3 compressors in a row".

Now I think this shows a fault in how people ask these kind of questions- or rather, the results they hope to achieve. They want to find an answer or technique that they can just plug in to their current routine to get the same results as the one that they are getting the advice from. But it is totally out of context. Whatever Jimmy is doing in other parts of his mix means he doesn't need to use comp on the buss. Brendan on the other hand is working towards using that, and I'll bet is running some sort of compression from the start.

Mixing (and production) is like cooking. There are lots of ingredients that must be added at the right time, in the right order, in the right amounts to get the right results. Yet strangely it might come out differently the next time. And someone else might cook something equally as good, but take a different route.

* * *
A few other interesting notes from that panel:
I asked both of them how long they spent mixing a song. Jimmy: 2 or 3 days. Brendan: 5 to 6 hours.
Was it true that Brendan uses the same bass guitar that he’s had for years with the same original strings on every song? (this based on a rumor I’ve heard around Atlanta from a few people) “No!”, he laughed. While he does have a favorite bass and the strings might be old (he didn’t really know when they’d been changed, so they are probably old) he doesn’t use it on everything, just when appropriate. Again, think of the context. I’ll bet there are several rock producers who heard this rumor and stopped changing their bass strings.

Learning How to Mix



How did I learn how to mix?


Man, I can’t really say. I’ve been doing it so long and have tried so many approaches- I've had a few work out great and had an incredible number of failures. I’ve read books & magazines, I've harassed older engineers. I’ve mixed loud, quiet, with headphones, on state of the art speakers and on cheap stereo speakers. I’m still learning and still frustrated with the outcome a lot of the time. But the one thing I’ve done that made the biggest difference was to train myself to listen. And one of the best ways to do that is by comparing your mix to a great mix of a hit song that you are familiar with. Here is how you do that:

Take your stereo returns of the mix you are doing and the stereo return from a cd player (or your computer output if you can play cd’s from it independently of your Protools/Logic/DAW output), and put them side by side on your mixer. Go back and forth between your CD and your mix and check the levels on your mixer so that they are the same. Have your mixing un-muted and the CD channels muted. Now, as you are listening to your mix put your fingers of one hand over the mute buttons on your mix and your fingers of your other hand over the mute buttons of the CD channels and press at the same time, quickly switching between your mix and the mix of the hit song. Now the differences will really jump out! Your goal is to make your mix sound like the other. Just try copying it.... I dare you. It is harder than you think. Keep in mind that it helps if the songs are of a similar type, vibe, tempo and so on. The bass is very important, too- If your mix has a lot of short and fast bass notes, but the mix you are comparing to has really long notes, you will never match up because of how bass reacts in the mix, on your speakers and in the room (this is a whole other subject to be covered in my workshops or lessons).

When I first started doing this it nearly drove me crazy. I could hear that my mix didn’t sound as good but I couldn’t place my finger on what the problem was. I had to start removing elements from my mix one at a time and see how that changed the comparison process. After doing this for years I trained my ears to hear things I could never hear before.

Here are two other techniques you can use by applying the same process:
1. Compare two mixes of two different hit songs against each other.
This requires two CD players. You will be amazed by how different the mixes will be sometimes. This is because mixing is not just a science- it is also an art. And a good mixer takes many aspects into account to get a good mix. Mixing is not just about sound but about emotion, and that has to be shown in the spotlight.
2. Use the comparison process to define ranges.
Years ago I pretty much just mixed rock music, which is much more challenging to mix than urban stuff (for me at least). I was always concerned about my low end, how loud the vocals were and how much mid-range I had in the mix. What I did was use 2 songs that were somewhat current to compare to. One was the Goo Goo Dolls song Iris mixed by Jack Joseph Puig. The other was The Verve and their songs Bitter Sweet Symphony and Lucky Man (or anything else off that amazing album) mixed by Christopher Marc Potter. I noticed from comparing them that the Goo Goo Dolls had a tremendous low end, a scooped mid-range and a somewhat lower vocal level. The Verve mixes tended to have way more mid-range and the vocals were mixed a bit louder. So I would do my mix and then make sure that my mixes had no more low end than the Goo Goo Dolls and that the vocals were as loud or louder than theirs. I would then make sure that my mixes were no more mid-rangy than the Verve mixes and that my vocals were no louder than theirs.

Of course then it was out to the car test, the hallway test and so on.

This is just one of many techniques you can use to train your ears and improve your mixing. I hope this helps some of you.
