MasterCheck 2

MasterCheck 2 is a metering and reference plugin that addresses a persistent problem in modern music production: the inability to audition how your masters will actually sound to listeners across different playback systems and streaming platforms. Rather than a processor that colors sound, it functions as an analytical and simulation tool, allowing engineers to preview loudness normalization effects, codec artifacts, and platform-specific processing before final delivery.

The plugin measures according to ITU-R BS.1770-4 standards, displaying integrated loudness, true peak values, PLR (Peak-to-Loudness Ratio), and PSR (Perceived Loudness Range) simultaneously. Its core strength lies in the Codec mode and Offset Match function, which simulates how audio degrades when encoded for Spotify, Apple Music, Tidal, YouTube, SoundCloud, and other major platforms. This preemptive approach eliminates costly mastering revisions and prevents the common scenario where a carefully balanced master sounds noticeably compromised on streaming services.

MasterCheck 2 scales from stereo through 7.1.4 surround formats, making it equally valuable during mixing stages where mix engineers can catch overly compressed or hot recordings before they reach mastering. The resizable interface adapts to portrait or landscape workflows, fitting naturally into different DAW layouts without consuming excessive screen space.

For mastering engineers and serious producers working in an era where streaming-optimized delivery is non-negotiable, MasterCheck 2 functions as essential reference equipment rather than an optional tool. It transforms platform normalization from an unknown variable into a controlled, predictable part of the mastering workflow.
