About Us

Since 2012 we’ve helped 5,793 artists step their sound up.

Founded in January 2012, ADG Mastering is a Toronto based online mixing and mastering studio that strives to help independent artists all over the world by giving them mixing and mastering services comparable to what you’d hear from an artist on a major record label.

Our mission since day one has been to level the playing field for all musicians so that the best music is heard loud and clear, and not just the music with the biggest marketing budget.

We believe in the following 4 principles:

1. We respect your art.

This means we treat each and every song on a case by case basis. If your song is in a particular style or genre, we respect genre conventions but at the same time, hope that you want to break some rules when they don’t produce a great sounding song.

2. It’s all about the song.

The most important thing is the song and that you’re happy how it sounds at the end of the day.

3. We tell it how it is.

If your mix or recordings doesn’t sound good, we’ll tell you straight up. There’s no point in us mixing and mastering a song that’s less than great. However, we give you the benefit of the doubt because we know you’re an artist and you know what sound you want.

4. Make the world a better (sounding) place

We believe in the saying “Leave the world a little better than you found it”. We hope to leave you better off from having interacted with us and strive to help you reach your goals as an artist.
