  • I went to Cefe Flynn with a single track after a bad experience with a recording studio. Cefe guided me through the options and we recreated the song, replacing some instrument parts as we went along. The standout feature of Cefe's service is his incredible ability to interpret client aspirations. The quality of the finished work is amazing.

what's in it for you.

My focus is on what is most important for both of us, your music career. Mastering is the last step in the production side of things but a great song and a great master alone will not get you too far. I have been an audio engineer for many years and seen over and over again that once the song is finished and ready for release most artists just haven’t thought about the next steps and don’t know what to do with their songs.

I’m here to help you not only to finish your songs and get them release ready but also to provide with guides and tips on this beautiful but complicated journey of releasing music to the public.

Personal and fully focus attention to your music

Unlike automated mastering engines, I'll be fully dedicated working on your tracks

Mix Feedback & re-mix protection

If there's anything that might impact the final master - I'll provide you with feedback. Need to remix a song to fix a problem? I’ll happily master your track again.

unlimited revisions

Each track includes unlimited revisions so we can work together to help you create the sound you’re looking for.

A Little bit about myself and the reason for this page

My name is Cefe Flynn, mastering engineer based in Sydney, Australia. Early on in my career as a recording and mixing engineer, I was amazed to see just how many artists skipped mastering- simply because it was too expensive or too hard to find the right engineer. Yet mastering is so important. It’s the only way that your music will be able to stand out or even be accepted in the music industry.

Independent artists shouldn’t have to miss out on the benefits of professional mastering. That’s why I launched my online service, Cefe Flynn Mastering – to bring high-quality, professional and affordable mastering to all artists – no matter how big or small.


Frequently Asked Questions

There has never been an album worth mentioning that was not properly mastered by a professional engineer. Most artists understand the music-making process except for the final and most crucial step. Mastering isn’t just about making your song as loud as possible. It’s about balancing your track to translate better and provide a great listening experience to your audience. You can learn more about what is mastering and why is necessary at all here.

Searching for mastering engineers on Google is confusing right? From Grammy-award winners to automated mastering engines – so… How do you know who’s worth paying for?
