Online Mastering & Stem Mastering

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.

After taking Matty’s course, it upped my mixing game tenfold!  I’m now mixing my material for releases on Spotify.

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!!!

Incredible service and the quality is superb! The best at making your sound even better than you could hope for! Definitely 5 stars.

Matty is fantastic. We've been working together for years and he's professional, timely, and talented. His mixes always sound crisp and I've gotten positive feedback from plenty of unbiased sources. Also his pricing is very fair. My standards are high but I would 100% recommend him to others.

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. Love this dude!

Matty’s an artist’s engineer, he understands the direction of the song and brings out all of right parts while maintaining the integrity of the mix. He’s definitely my go to guy for mastering.

Matty's extensive experience in the industry shows in his work. This course bridges the gap between bedroom artists and major names.

One of the best to ever do it! Mix and Master My Song is where it's at! Awesome team!!
