Stereo Mastering

Stereo audio mastering is the final stage of the song recording process. It is time to achieve commercial loudness and add any final touches of brightness, warmth, or bass to the song. Mastering is the icing on the cake. 

Stem Mastering

Stem Mastering allows us to do a Stereo Master but with more detail. When choosing a stems master, you send 4-5 tracks of your mix, usually Drums, Bass, Music, and vocals. We then can process a standard Stereo master with the ability to make the drums hit a bit harder or make the vocal just a bit louder. It’s a great option if you aren’t 100% happy with your mix. 

Apple Digital Masters

Apple Digital Masters aim’s to ensure the highest quality for music released on Apple Music. We are an Apple Certified Mastering Studio, so you can be sure you’re masters will be delivered for the best quality on Apple Music.

Vinyl Mastering

When releasing songs on Vinyl, a few alterations may need to be made to get the best pressing you can. Matty has mastered hundreds of songs for vinyl release, so you can be sure you will get the best sound.

Pick Package

The first step is to pick if you want to do a stereo master or a stem master. Next, you pick any extras you might need and make the purchase. Once you make a purchase, you will be directed to an upload page.

Upload Files

I ask that you send the files at the same bit depth and sample rate that the song was mixed at. Also, if you had a limiter on your mix, please send me a version with the limiter and one without it. If you can send a picture of the limiter you used that would be fantastic!

Get Your Master

You will typically receive your master’s within 2-3 business days. Once you listen, you can let us know if you need any adjustments. All masters come with 3 revisions, but 95% usually only need one at the most.

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.
Deciding to work with Matty is without a doubt one of the best decisions I've made since the start of music career. Great guy, incredible production and super quick turnaround. ...
