A Tested Third-Party Perspective

At its core, mastering is a process that relies on the expertise and experience of a third-party, well-trained, focused, and creative sound expert with the aim of elevating an artist's recording into its final form.

Mastering should always respect the intent of the music and the mix and obtaining the insight from an impartial perspective is vital toward the end of your project.

Thousands of clients have put their trust in Nathan's expertise to provide just that, and with remarkable success.

Quality Above All Else & Confidence in Your Masters

The audio mastering process is full of potential pitfalls and challenges, yet professional and timely mastering outcomes have never been more essential.

We collaborate with our clients (often under tight deadlines) to create masters that are perfect when they leave our mastering studios, and we are always willing to go the extra mile to ensure our clients are completely satisfied with their masters.

Our repeat clients tell us time and time again that we get it right the first time, and they come back to us because they have faith in our ability to deliver the best version of their recordings.

With these tools and techniques we can ensure your masters are submitted according to Apple's standards on high resolution delivery and that they rise above the rest of the pack.

With today's technologies we can remove distortions, air handling noise, cracks & creeks, pops & glitches, etc. We've even removed baby cries from reverb trails and none were the wiser. So whether from tape, vinyl, cassette and even digital formats such as DAT, CD, Minidisc, etc, we can bring your recordings into the modern era and provide you with a technologically updated version of cherished and important recordings.

What Our Clients Say

Not only did Nathan do an incredible job mastering, but without a molecule of ego, he produced three different masters for us, each meeting a completely different need. He understood what we were going for and pulled it off while maintaining the highest level of sonic quality.

John Medeski
Composer / Musician

Just listening to the mastered tracks from our session earlier today.  I am knocked out with the way it sounds!

Michael Kocour
Pianist & Director of Jazz Studies at Arizona State University

Nathan has a genuinely sensitive touch that graces all of his work, and I am constantly in awe of the often subtle but always brilliant work he does to refine those things that just slip under the radar with most people. A musical, brilliant, sweet, thoughtful, and dedicated human being. I absolutely adore working with Nathan and The Vault.

D. James Goodwin
Recording / Mixing Engineer

This master sounds amazing, super clean, I LOVE the quality of the vocal and the bottom end hits great- You nailed it!

BARii
Music Producer

My hat is off to you good sir. I'm just checking out the masters back at the studio now and they sound amazing. The masters are unmistakably the mixes that we've been agonizing over, however, refined; enhanced. All the nuance and detail has been preserved, but the intent is more portable now.

Brian Bender
Recording / Mixing Engineer

Amazing job!! I always think my demo masters sound pretty good, and then I hear what you do and I’m just blown away. So open, with so much more clarity and separation. Excellent job!

Thanks again! And thanks for being able to fit it in last minute right before you left out of town.

Stephen Moyer
Mixing Engineer

The whole experience with Nathan and Vault Mastering was exceptional! I knew this process would make a big difference in the sound of my project, but Nathan really takes it to a whole new level. This guy knows what he's doing - HIGHLY recommended!

John Willis
Independent Musician

Oh Nathan, you bring joy to my day.....

Those songs are full of life now for sure. Great job! They have even more energy than they did before. I'm like a proud dad right now!  This is the happiest I've been after getting a master back.

This is the reason I tell my bands to use you is because your masters comes back right the first time and no one's time gets wasted.

Evan Coffman
Mixing Engineer / Music Producer

Dude, all I can say is wow! You exceeded my expectations!  Thanks to you, my recordings now have a great warm round glow to them. AWESOME  !! Thanks for the great work, I will never do another project without you doing the master.

Carl Fischer
Independent Musician

To his followers:

I just got the masters for the movie score I finished with Nathan James at Vault Mastering. Nathan used to be an assistant to Scott Hull at Masterdisk and has worked on most of my previous albums with Scott. He is now running his own outfit (Vault Mastering) and this is the first time he's mastered my music by himself.  He did a fantastic job with it! It sounds unbelievably good and it was a pleasure from start to finish as we mixed the sound and Nathan's masters.

Thomas Dybdahl
Singer-songwriter

Hey man - just took a listen.  Sounds great! 100% approved. Thanks again for a great job, it really kicks ass.

Sean Han
Unicorn Taxidermy

Just wanted to say thanks again for the beautiful and thoughtful work you did mastering the new Midnight Moan record. It sounds just like I wanted it to. Much obliged! I'll keep you posted if we end up needing vinyl audio mastering.

Andrew Bradbury
Midnight Moan

I just wanted to follow up with you re: you’re mastering on Light of My life. It sounded excellent!

In fact, I’m really happy with all the work you did for the Exodus project.
Thank you again for being so pro and for a job well done.

Troy Samson
Mixing Engineer

Hey Nathan, I literally dropped my jaw after the first 5 seconds. I sent both mastered tracks to the guys in the band and they're very impressed. The vocals have a great dimension and are sitting perfectly with the ensemble. Thank you !
