Mixshi is a self-check tool for your own music tracks before release. Pick a 15-second hook or drop, and Mixshi rates your mix from its acoustic features. ▼ What you see - Release-readiness score (out of 100, 5-tier verdict) - Measurements: loudness (LUFS), sample peak, dynamics (DR), phase correlation, stereo width — each with a 2-tier ideal/acceptable visualization - 5-band frequency balance with delta-dB chart - Reference badges for shape-based observations (mid dip, steep high rolloff, downward tilt, etc.) - Mix Master's note: AI commentary on what's working and what to change, observation-based and genre-agnostic ▼ Design philosophy We do NOT use genre as a premise. Pop, hip-hop, dance — if the mix is solid, it's solid. AI commentary follows the same shape-based observation, no "this is how Pop should sound" assumptions. ▼ For - Self-checking your own tracks pre-release - Understanding LUFS / DR for your own track - Honest feedback on a 15-second hook or drop - Acoustic-quality view, not genre conformity ▼ Free vs Pro - Free: ad-watched analysis. - Pro (¥500/mo): up to 100 ad-free analyses per month using the upper-tier AI model. After the 100/month cap, you can keep going with ad-watched analyses using a lighter model. The upper-tier monthly cap auto-resets at the start of each month. Analysis itself takes about 5-15 seconds (AI + DSP). We don't claim "instant" or "zero wait". ▼ Privacy Your selected 15-second clip is sent through our backend to the AI provider. After analysis, no audio is stored on our servers. See in-app privacy policy for details. ▼ Future We are also considering future enhancements such as reference-track comparison. ▼ Note Results are reference information only. We do not guarantee commercial release outcomes, streaming-platform playback quality, or revenue.
