LISTENERS is a professional audio mastering service based in the heart of classy old West-Berlin. We offer:

• Mastering for Digital Distribution (incl. "Mastered for iTunes")
• Vinyl Mastering
• CD Mastering (incl. ISRC / DDP encoding)
• Audio Restauration


IDEA: We consider mastering both, a creative and a technical process. Based on in-depth listening sessions, it not only includes overall sweetening, equalization and dynamics adjustments, but also cleanses your music of unwanted remaining noises, clicks and distortions. With your input and by bringing in a fresh and specific perspective on your mixes, we realize a sound concept that turns raw material into a consistent, well-rounded and nuanced listening experience well fitted to the medium preferred, be it a Vinyl record, CD or digital album. We will ensure that your music will, once it is out there, translate well onto the various media of contemporary music reception. To achieve this, our studio is equipped with an array of lovingly arranged analog and digital signal processors by HEDD, RME, SPL, Rupert Neve Designs and Gyraf Audio.
