About Mix Analyzer for Musicians, Producers & Sound Engineers
Learn how our AI system analyzes your tracks with 21 modules and turns technical data into practical mixing and mastering recommendations.
Advanced AI-Powered Mixing and Mastering Analysis Technology - 21 Professional Modules
Mix Analyzer combines advanced audio analysis algorithms with AI to help musicians, producers, and sound engineers build professional-quality mixes and masters. The platform includes 21 analysis modules spanning mix and master quality: loudness and true peak (LUFS / dBTP) with per-platform streaming targets, dynamic range, frequency balance with sibilance control, stereo and 3D spatial imaging, clarity, transients, noise and artifact detection (noise floor, mains hum, hiss), source/format quality (lossy detection), reference matching against genre targets, plus descriptive analysis like voice detection, genre classification, mood, and instrument detection. Web analysis options include a monthly free allowance, Supporter plans, and token purchases. API integrations use module-based tokens for programmatic workflows.

AI Technology Insights
Signal-processing modules produce the measurements first. A configured AI provider and model can then turn those results into plain-language suggestions.
Configurable AI Interpretation
The selected AI provider and model can vary by account and configuration. It receives technical measurements from the analysis pipeline and returns mix feedback; it does not replace the underlying audio measurements.
Genre-Specific Analysis
Our AI automatically detects the likely genre of your track and adjusts its recommendations accordingly. A hip-hop track requires different frequency balance and dynamic treatment than a classical recording, and our AI tailors its suggestions to match your musical context.
Genre Target Comparison
The reference module compares tonal-band energy and integrated loudness with built-in genre target curves when genre evidence is reliable. It does not compare the uploaded audio with a private reference-track database.
System-Specific Recommendations
Our AI provides recommendations for how your mix will translate to different playback systems, from studio monitors to earbuds, helping you create mixes that sound great everywhere.
Stereo Spatial Heuristics
The spatial module derives height and depth scores from side-to-mid energy and left-right decorrelation, then measures width consistency across short windows. These scores can flag a narrow or unstable stereo image, but they do not locate sounds in a 3D scene.
Enhanced Voice Gender Detection
Our significantly improved AI voice analysis uses research-based F0 thresholds, advanced formant analysis, and weighted scoring systems to accurately detect voice gender with enhanced confidence scoring. The algorithm now provides superior accuracy for contralto, bass, baritone, and tenor vocal ranges with comprehensive uncertainty handling.
