Audio mastering service

Mastering audio has changed a lot during the last decade or two. First, we had the loudness war, and everything had to be so loud, it killed the dynamics in the music. Now after Apple, iTunes and YouTube have agreed on the LUFS standard, things have changed. When music is played through these platforms, no matter how loud it has been mastered, it always plays in the same volume.

KW-Masteroing studios is approved with the Apple Digital Masters, which means we also deliver the Apple masters in "approved by Apple" correct formats.

Mastering from start to finish

The process

You can order an online mastering service for your song from us. What KW-Mastering studio does to your song, goes like this:

First the bad and conflicting frequencies are removed using very surgical equalisation tools. Then the side information of the song is processed in the same way and the mid information is also treated one more time separately. After this a broader EQ curve is implemented with two separate tools. Now it is time for the first, but a very gentle Limiter. The next step is to go out from digital into the analogue world, where the signal is further processed with several outboard Tube and non-Tube outboard processors. Finally, the final Limiter is applied and the song is rendered through high quality converters in a digital mastering workstation.
