Kim Rosen visiting Vintage King, Nashville

I'd like to personally introduce you to Knack Mastering. My name is Kim Rosen and I began my professional career as staff mastering engineer and all-around facilitator at a very well-known and respected audio mastering facility in the New York City area.


In late 2009, I dove-in head first and set up my own mastering studio. I had confidence many of my clients would continue to trust my ability to make their recordings sound their best and for their projects to run smoothly from start to finish. I've, thankfully, been able to build upon that client base and grow Knack Mastering into a vehicle for enabling me to do what I love. MASTERING AUDIO!


Kim Rosen is a GRAMMY® nominated mastering engineer who works out of her own "Knack Mastering" located in Ringwood, NJ, USA.


Kim grew up in the western Massachusetts town of Northampton. Realizing early-on that music was a driving force in her life, Kim poured herself into the local music scene while searching out a way to carve a path for herself. In the summer of 2001 a friend turned her on to a mastering studio in NJ that was looking for an intern. Kim jumped at the opportunity, moved to NJ and began her journey at the age of twenty one.


After a couple of years in production, training and assisting in sessions, Kim was given the opportunity to take on her own mastering projects. Over the next five years, Kim would rack up hundreds of mastering credits including notable projects from Jeremy Enigk, Franz Ferdinand and Dashboard Confessional.


In 2009 Kim welcomed the birth of her first child and decided...that to continue doing what she loved (audio mastering) and be the mother she wanted to be, she would build a proper mastering room off the side of her home with the help of world-renowned acoustician Chris Pelonis. The mastering room at Knack is a world-class listening environment, with analog and digital gear carefully chosen for its sound quality as well as its versatility.


Kim now has a growing client list that includes producers and engineers such as Ryan Freeland, Joe Henry, Paul Bryan, Will Yip and independent and major artists from around the world.


Kim’s mastered two Grammy® nominated albums: 2015 nomination - Best Blues Album for Bettye Lavette's "Worthy" and her 2016 nomination for Best Engineered Album Non-Classical for Bonnie Raitt's "Dig In Deep".


Other recent credits include a diverse spectrum of genres with artists such as Aimee Mann, Wynonna Judd,

Billy Bragg, Joe Henry, Jeff Bridges and the Abiders, Bonnie Raitt, Glen Phillips, The Barr Brothers, Superdrag, Title Fight, Rozwell Kid and Anthony Green.


She was fortunate enough to master the remake of the Johnny Cash album “Bitter Tears” for Sony Masterworks which features artists such as Emmylou Harris, Steve Earl, Kris Kristofferson, Gillian Welch and the Milk Carton Kids as well as the beautiful Rhiannon Giddens and Iron & Wine rendition of “Forever Young” for the Series Finale of NBC’s television series “Parenthood”.


Kim continues to build a client base of artists, producers, labels and engineers who trust her ears, her experience and, above all, her respect for their mixes.




Knack is located in Ringwood, NJ, just 30 minutes from New York City's George Washington bridge. However, in today's age of easy and secure file transmission, Knack has mastering clients from New York to Los Angeles, Nashville to London, Berlin to Bangalore and everywhere in between.


If you'd like to discuss whether Knack is the right fit for your next audio mastering project I'd love to hear from you.
