The Audio Mastering Specialists

The Mastering Engineer’s role in music production is to polish the final mix so it is aligned with the artist’s vision, well-balanced and consistent with other works in the same genre.

After spending weeks recording and mixing, living and breathing every note and effect from every angle every day, you’re too familiar with it to have perspective on how it sounds overall. After slaving and sweating over each individual element, you lose sight of the work as a whole.

You need fresh ears and a fresh perspective to rebalance, tighten, focus and adjust it so that the whole really is greater than the sum of its parts.

That’s what we do.

We are audio mastering specialists with over 20 years of experience in the industry, so we have the specialized skills to deliver a master that is true to your artistic vision and presents your work in its best possible light.
