With experiences working with Kelly Clarkson, Lil Huddy, Travis Barker, Cuco, EricDoa, Ellah Hale, Cousin Stizz, and more, I know what it takes to get your song across the finish line. Let’s work and make your song the best it can be!!
I want to help new and established artists get the best-sounding mix and mastering they can. As far as I'm concerned, the mix isn't done till you are 100% satisfied.
I have been mixing and mastering for over 15 years. I started in Boston, where I attended Berklee College of Music for Music Production and Engineering. From there, I worked at some of the best studios in Boston as the chief engineer. I now live in Los Angeles, where I have worked with artists like Kelly Clarkson, LIL Huddy, EricDoa, Wrabel, Cousin Stizz, A$AP Rocky, Cuco, and many more. I specialize in Pop, Hip-Hop, Rock, R&B, and EDM, but I love to mix and master all styles of music.
For Mixing, I use Pro Tools or Studio One, but you can send Studio One, Logic, or Ableton sessions, and I can open them. I mix in a hybrid fashion with a few choice pieces of analog gear. I master songs mostly in the Analog Domain. When it comes to plugins, I have just about everyone created. :)
Feel free to contact me with any questions regarding your project. I look forward to working with you!

Matty is not only a talented mix engineer, but he's also incredibly receptive to feedback. He was also extremely patient despite some delays on my end, and most importantly, was able to create a mix that really translates. He's going to be a go-to for sure.

Matty is one of the kindest most patient TALENTED people I have ever met. I’ve just done my first ever house music and I went in eyes closed and left it up to him to do what he needs to do and the first draft sounded so good that I was in shock for a few days cause usually anyone I’ve used never gets it this good the first draft. Not only that, he’s so so professional and so so SO patient that he dealt with every tweak I requested without getting upset or impatient. 100000% recommended.

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.
