Mix Check Studio is an AI-powered audio analysis and mastering tool for music creators. It provides objective feedback on mixes and masters, helping users identify issues such as integrated loudness, stereo width, clipping, and tonal balance. The tool offers four main features: Check (detailed analysis), Revive (restore older recordings), Enhance (fix mix/master issues at stem level), and Master (final polish for release-ready audio). Users can upload WAV, FLAC, or MP3 files up to 173MB. The service does not train on user music, ensuring privacy. Trusted by over 1.1 million tracks, it is designed for music producers, independent artists, and mixing engineers who want to improve their tracks before distribution. A free tier allows unlimited mix checks, while Mastering+ and Studio Pro subscriptions provide automated mastering enhancements.
