We do Mastering in the Box which means that we process the audio material with audio plugins inside the DAW. We use the best sounding and expensive plugins from Universal Audio, Sonnox, Fabfilter and more. Please have a look at our Gear & Tools page for a full description. 

Unlike other online mastering services that use automated software, we provide real personal mastering with a wealth of experience and refined musical tastes. We have fully control over the sound you want in our acoustic optimized mastering studio and we absolutely love to fine-tune music until it turns into a shiny diamond.

We know the industry standards and may support you with our Know-How.
