It is an honor to make you feel proud

  • Professional and reactive, a real pleasure to work with Aurelien. He mastered the remixes of our 25 years compilation with care and a rare precision without denaturing the dynamics and color of the tracks. We highly recommend him!

    Ben & Malone - Composer, Producer, BTRAX Records label founder - Paris, France
  • First mastering with Aurelien and I'm more than delighted! He is professional, attentive, takes time to do a job that few will do with such passion, and the result is there! He managed to push the audio materials to a maximum level without distorting the dynamics or the color of the tracks, it's not with everyone that you can have this kind of result today. And on top of that, he's a lovely human person. Long live AC7 Diffusion Mastering!!!
