I have worked 27 years in the music industry, originally as a Danish Grammy nominated producer. I turned full-time to mastering 17 years ago.
My back catalog contains more than 13,000 mastered songs, including numerous #1 hits. I have the pleasure of collaborating with talented, best selling artists around the world and I have received 184 certified gold and platinum awards.
But most importantly, I have a deep passion for music and getting the best out of the mixes for my clients - whether that is a multi-platinum artist on a major label or an independent artist or producer aiming for the right sound.
A satisfied client is the best ad

Re-mastering a classic
Caroline Henderson - Cinemataztic
When Sony Music wanted to re-release this seven times Danish Grammy winning album to celebrate its 20th anniversary, they approached me with the task of carefully restoring and re-mastering the original versions from digital archives.
Due to the helical scan write heads used for DAT this job included procuring several tape players to find a compatible azimuth for an optimum transfer, as well as gentle digital processing and spectral repair.
Jacob Bellens - Trail of Intuition
The 2018 solo album from Jacob Bellens (I Got You On Tape) on HFN Music (Trentemøller, Blaue Blume, Lydmor) was mainly produced by Rune Borup, whose signature sound includes wide and lush analog synths and deep bass.
The songs have Jacob Bellens' voice as the focal point, but also feature prominent drums, so the vinyl masters required full use of the dynamic range, a controlled stereo image and a focused low end.
