MonoCheck: Free Mono Compatibility Analyzer Plugin by SwimSounds
SwimSounds has released MonoCheck, a streamlined utility designed to take the guesswork out of stereo phase auditing. Available as a free download for macOS and Windows, this free mono compatibility analyzer plugin evaluates individual tracks, mix buses, or entire master channels to ensure mixes do not collapse when summed to mono.
Streamlined Phase and Correlation Auditing
Traditional phase correlation meters and Lissajous scopes require active visual interpretation, which can slow down fast-paced mixing sessions. MonoCheck simplifies this workflow by translating complex stereo phase relationships into direct, plain-language diagnostic feedback.
Instead of forcing users to monitor a fluctuating correlation needle or decipher complex stereo field visualizers, the plugin provides clear warnings when destructive cancellation or excessive out-of-phase energy occurs.
Key features include:
- Plain-text diagnostic verdicts on phase correlation and mono safety
- Low CPU footprint suitable for multiple track inserts and sub-mixes
- Real-time stereo balance and phase monitoring
- Zero-latency processing for both tracking and mixing stages
- 64-bit VST3 and AU plugin support for macOS and Windows
Practical Mixing Workflow
Checking mono compatibility is essential for club sound systems, mobile devices, television broadcast, and spatial audio downmixing. MonoCheck excels when placed at the end of problematic stereo sub-groups—such as doubled rhythm guitars, wide synth pads, or drum room mics—flagging phase issues before they reach the final stereo bounce.
MonoCheck is completely free to download directly from the SwimSounds website without hidden subscription fees. It operates natively in 64-bit VST3 and Audio Unit formats on both Windows and macOS systems.
Head over to SwimSounds to download MonoCheck and secure your stereo mixes against phase cancellation.
