Mastering today is no longer a single-output process. Tracks are normalized, encoded, and reshaped by streaming platforms, codecs, and playback systems, often in ways that fundamentally change how your work is heard. MasterCheck 2 by NUGEN Audio is designed to solve that problem.

This latest release updates NUGEN Audio’s trusted optimization plug-in with expanded format support, improved performance, and modern workflow enhancements, making it easier to deliver masters that translate reliably across streaming, digital, physical, and immersive audio environments.

What’s New in MasterCheck 2

MasterCheck is an optimization plug-in for cross-platform mastering, designed to ensure that your masters sound consistent across all platforms: physical, digital, and streaming. Audition how loudness normalization will affect your track, and preempt the impact that each codec will have, alongside industry-standard loudness and True Peak measurement.

Building on that foundation, MasterCheck 2 introduces major upgrades that reflect how audio is produced and distributed today:

• Surround support up to 7.1.4 channels, suitable for immersive workflows and Dolby Atmos beds
• Expanded streaming service emulation, reflecting the evolving streaming ecosystem
• Resizable interface with a new landscape view, optimized for modern screens
• Completely rewritten codebase, ensuring compatibility with current DAWs and operating systems

Why MasterCheck 2 Is Essential for Modern Mastering

Streaming platforms apply loudness normalization and encoding that can dramatically alter perceived loudness, dynamics, and clarity. MasterCheck 2 allows you to hear those changes before release, not after.

By auditioning platform behavior and codec impact in real time, you can:

• Identify loudness and True Peak issues early
• Compensate for codec-induced artifacts
• Maintain musical dynamics without sacrificing competitive loudness
• Avoid rejected or compromised masters

This makes MasterCheck 2 especially valuable for streaming-first releases, where consistency across platforms is critical.

Built for Stereo, Surround, and Immersive Audio

One of the most significant upgrades in MasterCheck 2 is support for surround formats up to 7.1.4. As immersive audio becomes more common in music, film, and broadcast, mastering tools must adapt.

MasterCheck 2 enables engineers to apply the same loudness awareness and translation confidence used in stereo mastering to surround and immersive productions, without disrupting existing workflows.

Who MasterCheck 2 Is For

MasterCheck 2 is designed for professionals who need predictable results across platforms:

• Mastering engineers
• Mix engineers delivering final masters
• Music producers releasing to streaming services
• Post-production and broadcast engineers
• Professionals working in surround and immersive audio

If your work needs to sound consistent regardless of format or platform, MasterCheck 2 fits naturally into your mastering chain.

Master Once. Translate Everywhere.

With expanded streaming emulation, surround support, and a modernized engine, NUGEN Audio MasterCheck 2 helps you make informed mastering decisions before your audio reaches the audience.

Instead of reacting to platform changes after release, you can master proactively, with confidence that your sound will translate as intended.
