We Help With

Mixing & Mastering
your hit record

Your music is unique and you only get one chance to make a first impression. With so many independent artists with the ability to release music now, you must stand out from the crowd with proper mixing and mastering. 

Every song is mixed and mastered by Matty in our state-of-the-art studio in Los Angeles. He has over 15 years of experience working with Major label and independent artists.  Matty uses a hybrid of analog and digital processing and a monitoring system that costs as much as most cars. This ensures that every song is mixed and mastered to radio quality. Matty believes the essential part of mixing is conveying the emotion the artist is expressing through his mixing and mastering process. Please reach out so we can start working on your next project together! 

We Help With

Education and Training

More and more mixing and mastering are blurring with the production process. However, we feel that the current online education process doesn’t fully help. Watching a video of a mixing engineer mix a well-recorded song doesn’t give you all the answers. So we wanted to offer something unique that can really help your answer questions. 

1. One-on-One lessons with Matty. Classes are for 1 hour. You can sign up for a one-time class to ask questions you have or set up a weekly class where we can develop goals for what you are trying to achieve.

2. Templates and Courses. Our video course is a bit different than others. In Matty’s course, you get a mixing template to start with using only Slate plugins, so it is cost-effective. In the video course, he shows you how to use it with two song examples, and you also get the stems to practice with. What we really feel is unique is you can add the option to have Matty mix one of your songs with the template and send it back to you along with a short video from Matty explaining what he did and why. 

3. Plugin Presets. We offer a variety of presets for waves, slate, and FabFilter plugins. Presets are a great way to get the creative juices flowing and use for demos.

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!!!

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.

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!!!!!
