Mastering Hardware

My custom Crookwood transfer console allows me to seamlessly choose between a large collection of analog mastering equipment, so that I can choose the signal chain that best serves the music. No two projects are the same, and therefore there is no one tool that is perfect for every job. At Immersive Mastering, I have built a large collection of analog tools that help me to shape a wide range of music at the highest level.


The studio features a specific collection of analog and digital music analysis tools.

Digital Tools

Finally, I have a wide collection of the best digital tools available, to allow me to refine my masters to pinpoint accuracy. My plug-in collection is always expanding, and includes tools by Weiss, NUGEN, DMG, Leapwig, Fabfilter, Universal Audio, Izotope, GML, PSPaudioware, LiquidSonics and more.

All sample rate conversion processed using Weiss Saracon DSD.
