Q: How did you become a mastering engineer?
A: From the very beginning, I went to the University of Massachusetts at Lowell for their sound recording, technology, and music performance program.
Q: Were Alex Case and Will Moylan there at the time?
A: Will was, yes. Will started that program actually, in the â80s, well ahead of me. I went in the mid-â90s. Alex wasnât quite there yet. I think he came in as faculty a few years after I had graduated from the program, but of course I know both of them very well, and I stayed in touch with them. I know Alex well, and I know Will very well. Will was a professor of mine, and the director of the program when I was there. Both are great people, and in my opinion, they run the best program hands down for sound recording in the country.
I was a musician as a kid, and I really wanted to go to school for music performance. I wanted to be a rock star. I played in a lot of rock bands when I was a teenager, and when it came time to figure out what I was going to do with myself after finishing high school, I decided I really wanted to go to school for music performance. However, I had spent a little time in the recording studio as a performer and as a musician, and I thought, âWell, thereâs this great sound recording program not too far from me geographically at UMass, maybe Iâll check that out and see what thatâs about.â
Once I got into the recording program, my gears totally shifted to recording and audio, and then eventually to mastering specifically. Itâs interesting, youâre mastering guys as well, and Iâm sure youâve felt over the years that not many people completely understand what it is that we do because weâre such a niche part of the industry. When I was in school at UMass, I didnât know a lot about mastering, but I had asked Bob Ludwig to come and speak to our AES [Audio Engineering Society] Student Chapter during my senior year. I had asked a number of industry professionals to come and speak throughout the year, and every time I did, it was this great experience for me to get an overview of different potential careers in audio. I knew I really wanted to be in music production, and as I researched what mastering was, and then of course had Bob come down and speak to our student chapter of the AES, I realized that mastering was something I really wanted to do.
I then interned at a mastering studio in Boston and worked there for a little bit before getting a job as a production engineer here at Gateway in 1998. Of course, that was where, in both casesâin the studio in Boston and hereâthe rubber met the road. It was one thing to think maybe I wanted to be a mastering engineer, but then once I was having the experience in a mastering studio, I realized it was definitely what I wanted to do.
I donât know about yourself, but I know there are a number of people in the industry that didnât quite start out in mastering. They did tracking for a while, or mixing for a while, and found their way into mastering. That said, folks like Bob [Ludwig], Doug [Sax], Bernie Grundman, Ted Jensen, and a lot of those guys, started out in mastering early on, and that was really how I started. I did some multi-track recording, and I did some mixing, but very early on in my career I was working in a mastering studio. By the time I was about 25 years old, I was mastering records here at Gateway. So mastering has been the primary focus of my career since the beginning.
Q: How did you learn to master? Like you said, a lot of people arenât fully aware of what it is exactly a mastering engineer does. How did you learn that craft?
Well, I learned by being in the mastering studio and having the experience I gained in Boston. More specifically, I learned through experience here at Gateway. Within about a year of working as a production engineer, being a guy that did editing and cut production masters for Bobâs projects, I heard he wanted to have an assistant in the room. I really wanted to be that guy. So that was really where I learned the art of mastering, as Bobâs assistant for a couple of years.
I started by just hanging out with Bob in the room and seeing what he was doing. Bob gave me a little bit of a tutorial and information about what he was doing. This eventually led to me setting up for him in the morning before he got in, and then setting up and EQing (equalizing) tracks before he came in to start a session. That was really where the real learning of the art came into play for me, because I could set up the technical stuff I had under my belt at that point, and I could start EQing tracks.
Heâd come in and say âOh no, I would have done it this way, or that way,â or âThatâs too much top, or too much bottom.â Or whatever the case was. Eventually, though, he would arrive in the morning and say, âOh, thatâs exactly how I would do it.â So that work refined my ears and my skillset on the creative side of mastering to the point where we both realized that I had developed the aptitude and the temperament to be a mastering engineer. Bob said, âWhy donât you start taking on and developing your own clientele?â So it was really through that assistant-mentorship role, specifically with Bob as my mentor, that I learned the art of mastering.
Q: What a way to learn!
I like to say itâs like I got an Ivy League education in mastering!
Q: So what is mastering?
I like that question. It is a difficult question to answer, though, as you know. The way I describe it, in a nutshell, to somebody that asks me that question, is to say that mastering is a two-step process. The first âstepâ is the end of the creative process of making a recording, and thatâs of course what I do every day as a mastering engineer. The other âstepâ is prep for manufacturing and digital distribution. Because the creative side is what I do every day, and is the more interesting and exciting part of what we do, I would define that as the ability to make a recording sound as best as it can, and for it to translate well to the end listener, the fans of the band, and to whoever made the recording in the first place. My job is to make every recording that comes across my desk sound the best that it can and to help bring out the emotion and message of the music that the artist is trying to convey with their recording to the listener. Of course, thatâs what everyone is doing in the recording process, but weâre specifically at the end of that creative process. Weâre the last step.
Q: Were there any sessions in particular that stand out as being really important learning experiences for you?
Collectively, each and every one of them was a significant learning experience, in one way or another. One that just jumped into mind when you asked the question was a greatest hits record for the band Megadeth that I was assisting Bob on. It jumps out for me because it was a greatest hits record, not a typical studio album. It was a series of snapshots in time, with tracks that may have had different record producers, different mixers, different engineers, etc. Of course, as a mastering engineer, our job is to make it all sound great but also make it sound cohesive. As you know, with a greatest hits album, or a compilation, what we work on is much more varied than usual. I remember that one session being a struggle. As an assistant setting up, starting to EQ some of the tracks for Bob, and working with him on it, finding a common ground for all of the tracks was hard, and we had to accept the fact that some of them were going to live as they were. That one [session] sort of jumps out at me in a number of different ways as one where I learned a number of things that are mindsets and toolsets that I carry with me still today.
I remember with this one track, I was having a really, really hard time getting it to sort of stand up, or be loud, or have any bite to it, and I kept going for compression and limiting. Then I had Bob looking over my shoulder and saying âWell, why donât we just try opening up the top end, itâs really dull. I realized that having proper frequency balance was just as important for loudness as using a ton of limiting and compression. Those types of things, and that session in particular, jumped into my mind immediately as one where a lot of lessons that I learned in every session, every day, came together.
Q: What are the things that you typically listen for, or what sort of areas are you going to address, when you master, regardless of genre?
Thatâs a good question. Iâm one of these guys that jumps right in and starts working. Some mastering engineers may like to listen to a track down flat and see how it hits them before they start doing anything. I usually jump right in and start working. For every track, of course, the first thing Iâm going to focus on is any corrective EQ, or any corrective measures, I have to take with the mix. In other words, if things jump out as being just plain wrong, those are the things I need to address first before I can delve into the craft or more creative part of what Iâm doing. If thereâs too much bass response in the track overall, if itâs boomy, the first thing Iâm going to work on is getting that in line, fixing that, and making that work before I delve into anything else. So corrective EQ, or corrective measures, are the thing I look for first, which generally of course means that I start by creating a good overall balance, in terms of frequency response, that is appropriate for that recording. That would be the first thing Iâd be looking for.
Of course most of what I do would fall under the umbrella of pop music, so vocals are really important. During the first or second listen Iâd make sure that the vocals are hitting me just right. Are they present enough? Are they loud enough? Are they clear enough? Are they right where they should be? I work on very, very few instrumental recordings. Again most of the stuff that I do would fall under that pop music category in one way or another, whether itâs pop music being commercially released, pop, country, all of that So the vocal is so important.
Q: Do you have a preferred signal chain that you work with when youâre doing this?
Yeah, I do. For most mastering engineers, myself included, I think knowing your signal path really well is super important, and adding new things into it you do fairly cautiously, though Iâm not hesitant to add new stuff into it. In terms of my signal path, what my preference has been recently, and itâs changed in the past couple of years, but because virtually every mix is coming in digital now, and thatâs been the case for a long time, Iâm finding that Iâm staying all digital these days 99 times out of 100. If you asked me this question five years ago, I would say my preference was a hybrid signal path, even when given a digital mix. I would do a D/A conversion, I would use analog gear, and do a subsequent A/D conversion, use some digital plug-ins in-the-box, stuff, like that, but these days Iâm finding my preferred signal path is all digital. I use both Pro Tools and Pyramix. Those are the two workstations I use every day. I use Pro Tools for playing back mixes, and for plugin processing, and then I use Pyramix for the other end, as the final step of my signal path, not including my monitoring of course, but the final step in terms of where the processed signal goes. All of it will go into Pyramix, and all the final editing, and the final master export, happen in Pyramix.
Q: Will you take us through your conversion and monitoring?
A: Sure. These days Iâm using a Horus convertor, which is made by Merging Technologies, the folks that make Pyramix. I think they make the best-sounding converter on the market now, and so the end of my chain is Pyramix to the Horus for D/A (Digital-to-Analog conversion), through an SPL console; I have a DMC console, and Duntech Sovereigns are my monitors of choice.
Q: So you said that youâre mostly digital now. Do you have any bits of outboard gear that youâre still using nonetheless, somewhat regularly?
A: Not really, no. I do have a couple of TC devices that occasionally Iâll go into for various things. And I have some multifunctional devices, like the system 6000 or, believe it or not, the Finalizer. Occasionally Iâll go into one of those devices. In both cases, there are just a handful of algorithms or setups that I like in the devices, but itâs becoming even less and less common for me to use them. Iâm staying in the box almost entirely now. Itâs almost unbelievable that thatâs become the case, and I feel like Iâm getting better results that way.
Q: Me too.
A: Yeah, isnât that interesting? For many, many years, I felt like using analog was a really important part of my signal path, and I challenged myself to do more in the box a few years ago when I had a couple of very intense, very time-intensive projects. It was like, âSo, how am I going to get through these in a really efficient manner?â And I was like, âLet me see if I could do them all in the box.â Of course, if I couldnât I would have dealt with it. But I realized at that point that everything in the box had become so good, and subsequent to those projects I found that anytime I was going out of the box I was getting lesser results than I used to. I think that some folks still really like analog gear, and I think thereâs still some mythology around it, but Iâm definitely a convert to digital.
Q: Getting a little bit more into the nitty gritty, I wanted to talk about de-noising and editing. Do you do either often, and how much is either de-noising or editing actually a part of your practice?
Letâs start with de-noising. I think itâs something that happens every day, to one extent or another. For me, de-noising on almost a daily basis just means removing some clicks and pops and that sort of thing. Occasionally you get something with a lot of analog hiss, and maybe Iâll go after that if itâs bothersome. My general rule of thumb with de-noising is that if there is something that is not a musical component of the recording, and it takes me out of the moment when Iâm listening to it, then I need to address it. Thatâs my threshold of whether or not I need to de...
