I've worked with Kelly Clarkson, A$AP Rocky, Travis Barker, and Carly Rae Jepsen, and earned over 1,000 five-star reviews right here on SoundBetter. Whether you're signed or releasing your first single, I'll make your song sound like you, just better.
I'm a mixing and mastering engineer with 20+ years of experience and credits with Kelly Clarkson, A$AP Rocky, Travis Barker, Carly Rae Jepsen, Fat Joe, Danny Brown, Cousin Stizz, and many more. I'm Apple Digital Masters certified and ranked in the top 1% of both mixing and mastering engineers on Muso.ai.
I started at Berklee College of Music, then became chief engineer at one of Boston's top studios. After mixing Sammy Adams' album, the first independent album to hit #1 on iTunes, I moved to Los Angeles, where I've worked out of my own studio ever since.
What you can expect:
- A first mix that's already close. Most clients only need small tweaks.
- Fast turnaround: first mix in 3 days.
- A mix that keeps your identity. I won't make your record sound like someone else's.
- Clear communication from start to finish.
I specialize in Pop, Hip-Hop, R&B, Rock, EDM, and Country, but I love all styles. I grew up playing drums in Jazz and Rock bands, and spent most of my professional career in Pop and Hip-Hop studios, so I have a unique ear for music.
I mix in a hybrid setup with analog gear and the best plugins, and I master mostly in the analog domain. I can open Pro Tools, Studio One, Logic, Ableton, and Cubase sessions, or work from stems.
Tell me about your song. I'd love to help you get it across the finish line.

check_circleVerifiedOnce again, Matty delivered a great mix that truly elevated my song, adding texture, movement and creative input that gave the track a whole new dimension.
check_circleVerifiedI have worked with Matty a bunch of times now and he's the one I keep coming back to. Innately talented. Exceptionally attentive to notes and feedback. Fast turnarounds. I have worked with other engineers who make your band sound like... someone else's band. He makes you sound like you, just better.
check_circleVerifiedMatty's work is incredible - he's detail oriented, communicative and kind - this round we were dealing with a weird bug in a Logic file and he provided guidance and prompt revisions to resolve it. I can't recommend his work enough! He takes my music to the next level every single time!
check_circleVerifiedTrust me he’s the man you wanna work with. My whole EP and the next one too will be mixed by him.

check_circleVerifiedThis guy is great. Super professional, fast turnaround & great attention to detail. Def would work with him again!
check_circleVerifiedIt was a pleasure to work with Matty. The mixes sound fantastic and the first revision required only cosmetic changes. Matty is really professional, responsive, communicative and the turnaround time was super quick.
check_circleVerifiedFirst time working with Matty and already planning my second. He was terrific. First pass through was very close and we only needed very minor tweaks after that. Total pro. Nice clean sound. Thanks again Matty!
check_circleVerifiedProfessional. High quality results
check_circleVerifiedMatty is phenomenal - his work is super precise and high quality, this is my third time working with him and each time the result is exactly what I want - and far beyond what I could expect! He's prompt, super communicative and helpful in case something on my end goes awry - I can't recommend working with him enough! TEN out of five!
Interview with Matty Harris
Q: What do you bring to a song?
A: I like to say I bring warmth, width and I make the record sound expensive.
Q: Is there anyone on SoundBetter you know and would recommend to your clients?
A: Yes! Manny Marroquin!
Q: Can you share one music production tip?
A: Make sure you record in a room with lots of soft objects. Rugs,couches, heavy curtains are all really helpful to not having a bad sounding room sound recorded with your vocal take.
Q: What other musicians or music production professionals inspire you?
A: I’m a big fan of Jaycen Joshua and Manny Marroquin as far as mixers. To me they are the best at bringing a song to life.
Q: Tell us about a project you worked on you are especially proud of and why. What was your role?
A: The Sammy Adams album changed my life. It was the first independent album to go number 1 on iTunes. Also working on Kelly Clarkson's Stronger was a big moment for me.
Q: What are you working on at the moment?
A: I just finished Cousin Stizz's album for RCA and Lil Huddy's album with Travis Barker.
Q: What questions do customers most commonly ask you? What's your answer?
A: How do you want me to send the song! As I said previously I like one set of stems wet, one set dry and the current bounce you've been listening to.
Q: What's the biggest misconception about what you do?
A: That I can do magic tricks. :) It's hard to make a bad recording sound like a great mix. So I always try to be upfront with people what I can actually do with the source material provided.
Q: What questions do you ask prospective clients?
A: I like to know what DAW your song is currently in. Also, if you're not sending a session, I ask for the stems wet and dry so I can hear what you've been hearing for the last few months.
Q: What advice do you have for a customer looking to hire a provider like you?
A: Give me as much info as you can. Tell me if you like your rough mix, or if you want me to give you something completely new.
Q: If you were on a desert island and could take just 5 pieces of gear, what would they be?
A: Fab Filter Pro Q Burl B2 Bomber DAC Studio one 4 Imac Pro UAD Octo
Q: How would you describe your style?
A: Aggressive and Warm.
Q: Which artist would you like to work with and why?
A: Jay-Z. He's the Goat.
Q: What's your strongest skill?
A: Listening to the song as a fan. As a mixing and mastering engineer, you have to understand the technical side of things but if the song is moving you none of that matters. If I have to distort the vocals or do something else that isn't within the "rules" to make the song hit me, I will.
Q: What's your typical work process?
A: I tend to get my basic levels going, then add a touch eq and compression on the master bus. After that, I focus on the kick and bass and then blend the rest of the elements. Finally, I work on the vocals and make sure they sit perfectly in the mix.
Q: Analog or digital and why?
A: Both. I like using the best of both worlds.
Q: What's your 'promise' to your clients?
A: That they will be 100% happy.
Q: What do you like most about your job?
A: I like helping artist realize the full potential of their song, and the fact that everyday is a new song with different problems to figure out.
Q: What was your career path? How long have you been doing this?
A: I have been mixing for over 15 years. I started interning in Boston while I was in school at the Berklee College of Music. From there I moved up and became the Chief Engineer at one of the larger Boston Studios. When I worked on my first number one record with Sammy Adams I realised it was time to move to Los Angeles. Since moving I have worked with tons of great artist in my personal studio.
Q: What type of music do you usually work on?
A: I grew up on hard rock and hip-hop, but also played in a steel drum and jazz band. So I love it all!
Q: Tell us about your studio setup.
A: I use Pro Tools HD and Studio One Pro. I also accept Logic sessions. The music goes out of my computer to my SSL Summing Console to give me analog warmth and depth that I feel you can only get in the analog world. From there it goes to my all analog mastering chain. I use a Dangerous Music Compressor and a Bettermaker MKII EQ. In the computer I use a ton of different plugins from UAD, Waves, FabFilter, Slate and many more.
Q: Describe the most common type of work you do for your clients.
A: Bringing the clients ideas they have in their head to realization when it comes to mixing and mastering.
