The Room

Paul Abbott in ZenMastering main studio

A balanced, neutral listening/ working environment is the critical element that guarantees your mastered mixes translate successfully in the "outside" world. Attaining it is not easy.

From a perspective of acoustics, it starts with a good physical space...which means a high ceiling and geometrical asymmetry to avoid standing waves.

From there the fine-tuning of speaker placement, alignment, and absorption/ diffusion play a key role in accurate perception.

We've utilized many of the industry's best tools and techniques to make the ZenMastering workspace as accurate as possible. The result is a linear listening experience that allows us to make extremely accurate decisions.
