Overview

Merlin MTR puts every meter you'd reach for during a mastering pass on one screen: a vectorscope for stereo correlation, a panorama display, a triggerable oscilloscope, and an EBU R128 loudness panel reporting Integrated, Short Term and Momentary LUFS alongside Loudness Range and true peak per channel.

Underneath, a spectrum analyzer runs at 15, 31 or 62 bands with selectable peak hold, adjustable range and release, and a Mid/Side view for checking how energy is distributed across the stereo image, everything you need to confirm a master is ready before it ships.
