StemSentry

StemSentry is a desktop + web AI-assisted audio QC tool for independent musicians, mix engineers, and small labels who can’t afford mastering-house quality control. You drag in a stereo mix or stems, and it runs a fast, repeatable checklist: clipping and inter-sample peaks, phase correlation and mono-compatibility, harsh resonances, low-end masking, sibilance hotspots, dynamic range, loudness targets for Spotify/Apple/YouTube, and basic metadata deliverables. It outputs a clear “fix list” with timestamps, suggested EQ ranges, and export-ready reports you can share with clients. This is not a magic mastering button; it’s a pragmatic second set of ears that catches common mistakes and reduces revision churn. The goal is fewer embarrassing uploads, fewer client back-and-forths, and faster approvals—without pretending to replace real taste or creative decisions.
