Mastering Engineer

I could not be happier after working with John! His masters perfectly captured the vibe I was going for with my tracks. Not only was the final product exactly what i was looking for, but he also took the time to walk me through what he had done to achieve the result, which helped build my own confidence in the other projects I am working on. I greatly look forward to all future collaborations with John!

Our mixer suggested using John for mastering and boy did he improve our track. John took it from sounding like a fun recreational project to extremely professional. We’re yet to try anyone else for mastering and don’t plan on it so long as John’s in the industry!

I have collaborated with John many times.

He’s an excellent singer, and plays piano wonderfully. In addition, he has a great ear for detail which was evident from the way he puts his audio production skills to work.

I can assure you, your project will be treated with dedication and creativity and he will aim to get the very best out of your music.

Highly recommended!

John is an absolutely dedicated engineer, producer, and all around musician’s musician. Every song I’ve brought to him has become better than I ever expected it to be because of his talent and ability to take his clients ideas and expertly execute them in a polished and cohesive way. He also has amazing ideas of his own, that you’d be wise to listen to when working with him, but ultimately he wants YOU to be happy with the end product, and he won’t stop until you are. I absolutely wholeheartedly recommend working with him on all your projects

John is such a patient, clever, creative collaborator— his work mixing AND mastering the studio cast recording of my original musical completely elevated the material to sound the way I always hoped it could— better even. He takes into careful consideration all feedback and references you provide and he doesn't mind moving through version after version to get it right— he's also an absolute blast to spend a studio session with!

It’s always a pleasure to work with John. He’s incredibly talented and professional in everything that he does. Very patient and helpful during the process of creating. And he always makes sure that you’re satisfied with the final product. I’m looking forward to working with you again!

My name is Blake Rouse and I’m an indie folk artist. I first got linked up with John through a friend and immediately his friendly, creative vibe told me that this was someone I could trust to master my music. Mastering is just as important and valuable as any other step in the music making process, and you can bet that John Osborn recognizes this and works meticulously to create the sound profile that you’re looking for. There is no one else I’d want to master my music!

I first collaborated with John on a song in 2020 and he has since been my reference point for mastering. John has an insane amount of knowledge in mixing and mastering which is down to his passion for his craft. But more than that, John has the ear for knowing what is needed and what is not, which is a great skill (and one which I'm jealous of). He's also the nicest and most humble dude ever and will go above and beyond your expectations!

John is so talented and professional and the only person I trust to make my music sound beautiful. He has an incredible ear and always knows how to elevate my sound, his prices are great, and he cares deeply about his work. I truly can’t recommend him enough!

The sweetest human and genuinely *the best* sound engineer I know! Can’t recommend him enough!

I’ve been lucky enough to know and work with John on several projects at this point (with more on the way!) and each and every time, he has taken what I gave him to work with and *ran* with it to a place where it can soar and reach its full potential. Sometimes it honestly feels like witchcraft, but no: he’s just that good. Most importantly though is the complete trust I am able to put in him and the comfort of knowing that my music is in the best possible hands. I am so grateful to have such an amazing producer! <3

John is an absolute gem of a human who happens to be insanely talented on top of it. Not only does he bring the utmost professionalism to the table, but he makes the production process fun and approachable for those who are less experienced, and he offers creative insights while honoring the artist’s own vision. His mad skills continue to impress me even after years of working together! :)

I've been incredibly lucky to have John mix and master my 5-song EP. He brings technical chops, creative energy, and a deep commitment to doing what's best for each song. John is always kind, constructive, and responsive in his communication, and is very receptive to feedback. I'll continue working with John as long as I can, and I recommend you do too!

John is a dedicated and one of a kind when it comes to his work. He cares deeply about each project he works on and it shows. He is flexible with his sound to fit the needs of his clients and he can also work in collaboration, providing unique ideas and sounds that take the song to the next level. I have been working with John for over a year on an album and I couldn't imagine working anyone else. I am unbelievably happy with our products so far and can't wait to finish the rest off with him!

John is the best in the business. His care, patience, work ethic, and drive put him above the rest. John works his magic to make you sound the best you possibly can in an environment you feel completely safe in. My wish is that all artists get the chance to work with John. His skill set is unprecedented.

John is smart, incredibly friendly and professional, and an insanely skilled mastering engineer. I couldn't have finished my last project without him. Would 1000000% recommend him for any mastering needs!
