Master at PKO

Mastering is the most important post-mixing process, and makes the difference between a professional and an amateur product. Our professional engineers perform as a “notary” a final check on the mix by adjusting dynamics, EQ and balance to make your production sound as full-bodied and harmonically rich as possible.
