Matty HarrisMixing & mastering engineer
Four hundred and ninety-nine records.
Every cover is a record I mixed or mastered, verified on Muso.ai.
Meet your engineer.
I’m Matty Harris. I’ve been mixing and mastering records for over 20 years, most of them in Los Angeles. Over that time I’ve worked with a wide range of artists, including big names like Travis Barker, A$AP Rocky, Carly Rae Jepsen, Cuco, and numerous others.
Most of the artists I work with I have never met in person. A song I mixed in a room in Los Angeles turning up on someone’s release on the other side of the world still hasn’t got old.
My mission is simple: bring major-label mixing quality within reach of independent budgets.
Before and after, in your genre.
I mix and master pop, R&B, hip hop, rap, rock, indie, country, EDM and Latin records. Every track below was recorded by a real independent artist and mixed and mastered in my Los Angeles studio.

“Spent years working with other mixing and mastering engineers, just settling for the results. Working with Matty, I finally get that sound, on each and every track, that’s even better than what I could have envisioned myself.”
“Great sounding mixes and easy, fast to work with. I’ve used a few comparable (and pricier) online mixers but keep coming back to Matty because the end result is superior.”
“I’ve struggled to elevate my mixes in the mastering stage without emptying my bank account, but that’s changed since going to Matty. He not only delivers 10x over from a quality perspective, he is reliable and easy to communicate with.”

Frequently asked.
Do you personally mix and master every song?
Yes. Every song is handled start to finish by me. Never an assistant, a junior engineer, or an offshore team.
How much does online mixing and mastering cost?
Mastering starts at $70 per song. Mixing and mastering together starts at $349, with an Elite tier at $449.
What do I need to send to get started?
Individual track stems exported from your DAW, or the DAW session itself. Pro Tools, Logic, Studio One, Ableton and Reaper all work.
How many revisions do I get?
First-time clients get unlimited revisions free. Revisions are turned around in 24–48 hours.
How long does mixing and mastering take?
3 to 5 business days for a single song, with revisions back in 24 to 48 hours. Albums usually take a week to a week and a half. A 48-hour rush is available.
Do you use AI to mix or master?
No. I make every decision by ear in my Los Angeles studio, using analog hardware and plugins. Your song never goes through an automated mixing or mastering service.
Do you work with artists outside the US?
Yes. Everything happens by upload and email, and I work with artists in 56 countries. Your time zone doesn’t change the turnaround.
Do you use analog gear?
Yes, analog and digital. Every master runs through analog mastering hardware, and analog gear goes on the mix where it earns its place.
What’s the difference between Pro and Elite?
Same mix, same master. Elite adds mixed stems, a show mix and a clean mix, plus unlimited revisions on every song.
