How We Can Help

Online Mixing & Mastering

All songs are mixed by Matty in our beautiful studio in Los Angeles, California using the best plugins and analog equipment for that warm, punchy sound you hear on the radio. You receive perfectly tuned vocals with Melodyne and Auto-tune correction, drums replacement when needed, and precise vocal alignment. The final master is processed through analog mastering gear for a polished, professional sound that translates across all platforms. First-time clients get unlimited revisions (with code) until you’re completely satisfied with your mix.

Stereo Mastering & Stem Mastering

Whether you need stereo mastering for complete mixes or stem mastering for more precise control over individual elements like vocals, drums, and instruments. Every project gets tailored treatment based on your specific needs – whether it’s vinyl mastering, Apple Digital Masters, or standard streaming formats. You’ll get professionally mastered files that sound polished and competitive across all playback systems. Album projects receive exclusive discounts.

Vocal Presets & Mastering Presets

Enhance your music production with Matty’s expertly crafted vocal and mastering presets. These presets utilize the same techniques and plugins Matty uses in his mixing and mastering projects for leading artists.

Coaching & Courses

Interested in a DIY approach? Need more guidance to perfect your mix? We offer personalized one-on-one sessions and comprehensive courses tailored to help you achieve the ideal mix. Whether you’re honing your skills or just starting out, We can provide the expert support necessary to attain professional results.

How It Works

Pricing

Purchase & Upload

Once you purchase mixing and mastering services or mastering only , you’ll receive a confirmation email with an upload link.  Upload your stems, and Matty willl take care of the rest. For details on how to best prepare your files, check out our FAQ.

We Mix Your Song

As soon as we receive your files, We schedule your song and get started on the mix and master. Everything is done in our world-class studio, and the usual turnaround time is 3 to 5 business days.

You Receive the Mix

Once the mixing and mastering is complete, Matty will send the Master over for your review. From there, we’ll begin the revision process to make sure everything sounds exactly the way you want. We’ll make any necessary adjustments until you’re fully satisfied.

Direct Access to a Proven Pro

Unlike larger services where your song might be passed between engineers, Matty personally handle every mix and master. With credits including Kelly Clarkson and Travis Barker, you’re getting a seasoned pro dedicated to making your track sound radio-ready — not just good, but competitive.

Unlimited Revisions Until You’re Happy

Some mixing and mastering services limit how many revisions you can request. We don’t. We offer Unlimited Revisions so you can tweak your mix until it’s perfect. And for first-time clients, Unlimited Revisions are completely free — no pressure, no hidden fees.

Fast, Streamlined Workflow

Once your files are in, we get to work right away. Most mixes are delivered in 3–5 business days, and revisions are turned around quickly so your project keeps moving forward.

World-Class Sound, Fair Price

Matty’s  reputation as an audio engineer comes from results, not inflated rates. Our mixing and mastering studio is equipped with the same analog gear and plugins the big players use, but our rates are designed to be accessible for independent artists who care deeply about quality.

DJ Pleez
Matty is my go-to mixing and mastering engineer. I have been working with him for several years and he has essentially become an extension of me and my creative team. The quality of his work is the result of the intention and focus he puts into every project. My trust in his sonic choices goes so deep that I defer most (if not all) of the post-production mixing and mastering decisions to him. I'll get something back and if there are changes needed, it's usually of the personal preference variety. The overall quality of his work never misses. He never disappoints. If you have a project on a scale of 1-10, with 10 being the best, sitting at say a 6 - I can guarantee, Matty is the guy who can take it to 20.

I'm Portuguese so my album was composed and written in Portuguese. I was expecting some issues regarding that. But Matty dealt with it like if he was working with English written material. Amazing sound! The orchestration was complex but I can hear every single detail on each song. Amazing mixing, better mastering! And Matty is a fantastic guy with a lot of patient to endure all my requests!!! I can't recommend enough!!!

I have never before worked with a more professional studio engineer than Matty! Matty is a perfectionist that delivers his mixes at the highest quality level. Even though he has worked with some of the most successful artists in the world, he treats every client the same way. He treated us very nice and respectful from the get-go and we could tell that he wasn’t going to be satisfied until we were. We have booked Matty several times and he delivers the same high level every time. And that he is using high quality equipment is a big plus. We would highly recommend Matty Harris as your studio engineer anytime.

I have never had anyone mix or master my music, so I was VERY nervous letting someone do this to songs that are important to me, but Matty and his team exceeded all of my expectations and made everything sound 1,000% better than it ever has. They were EXTREMELY kind and went above and beyond to make sure we loved how our track sounded. I HIGHLY RECOMMEND MIX AND MASTER MY SONG!!!!!
