What is mastering?

It is the art of enhancing and correcting the sound of a final production by an artist, producer, musician, hit maker, person in order to make it almost perfect to the ear, at least for most people's taste.


What is online mastering?

Like mastering but it is NOT required to be in the studio for the mastering session due to the help of the internet. The creator sends their music by online methods. This avoids the need of going to the studio, it saves plenty of time and reduces costs, especially if you're located in Australia, our studio is located in Los Angeles, CA.


What's your mastering gear?

We use software and hardware for mastering, for privacy, we don't reveal the exact items we have in our studio but we can share the brands we work with such as MANLEY, Ableton, Solid State Logic, beyerdynamic, ADAM Audio, V-Moda, Apple, Waves, iZOTOPE, elysia and many more.
