Why a free master from mastering.studio sounds so good

With the exception of the final conversion to format, the processes and tools used to create free CD Masters are exactly the same as those used in our paid masters.

This unique mastering process is the key to the exceptional quality of these free online masters. It is the work of two icons of audio engineering: Brainworx and Plugin Alliance, overseen by Founder of both companies — Dirk Ulrich. This process combines industry-leading mastering tools with a decision process inspired by legendary masters from some of the greatest mastering engineers of all time.

The online mastering processes: the tools we use

To create your free online master, mastering.studio uses processes and tools adapted from Brainworx mastering plugins which are famous for delivering studio-quality analog sound through patented Tolerance Modeling Technology (TMT).

The online mastering processes: machine guided mastering

These studio-quality mastering tools are combined with a machine-guided mastering process, developed by painstakingly matching landmark masters from Grammy-Award winning and nominated mastering engineers including Howie Weinberg, Fragancia and Zino Mikorey. The essence of what makes these masters great is what guides mastering.studio’s process.
