What MasterCheck 2 does

The plugin is aimed at finding the balance between perceived loudness and dynamics, so that a master avoids surprises when it reaches a listener. Cross-platform loudness optimisation is described as a concern mainly for mastering, since a mix that is too hot or over-compressed leaves no room to move further.

The metering centres on Integrated loudness, PLR, PSR and True Peak, the set the developer selects as the sensible reference. The plugin supports up to 7.1.4 channels, enough to receive a Dolby Atmos bed or other immersive material, and its resizeable portrait and landscape views let it fit into practically any layout.

Key features

• Loudness balance view. The plugin is meant to find the point where perceived loudness and dynamics sit in balance, so the master can be checked before it leaves the studio.
• Reference comparison. A reference compare view puts the mix beside other material to show how it sits against a known target.
• Core loudness readings. Integrated loudness, PLR, PSR and True Peak are the reference values the developer selects for the meter.
• Immersive channel support. Up to 7.1.4 channels are supported, enough to receive a Dolby Atmos bed or other immersive material.
• Resizeable layout. Portrait and landscape views can be resized, so the plugin fits into most session layouts.
• Client demonstration. The developer describes the plugin as a demonstration tool for clients who still believe a louder master is always better.

Who it is for

The plugin suits mastering engineers and mix engineers who want to compare loudness and dynamics readings against a reference before a master is delivered, and who work on stereo or immersive material.
