Frequently asked questions
Answers for licensing, quality, and workflow
How accurate is the key detection?+
Key detection accuracy depends on the audio content. Tracks with clear harmonic instruments or vocals yield the best results (70-90% accuracy). Percussion-heavy or atonal music may produce less reliable results.
What file formats are supported?+
All common audio formats including MP3, WAV, AAC, FLAC, OGG, and more. The browser's Web Audio API handles format decoding.
Does it detect major and minor scales?+
Currently the analyzer detects major scales. Extended support for minor scales, modes, and complex key changes is planned for future updates.
Is my audio data private?+
Yes! All analysis happens in your browser using Web Audio API. Your files are never uploaded to any server, ensuring complete privacy.
What are compatible keys?+
Compatible keys are those that harmonically blend well together. The tool shows relative major/minor pairs and adjacent keys on the circle of fifths for smooth DJ transitions.
How is this different from AI Key & BPM Detector?+
This tool focuses exclusively on key detection with detailed scale information and mixing suggestions. The AI Key & BPM Detector combines both key and tempo analysis in one tool.
About musical key detection and harmonic analysis
Deep-dive context for AI-generated music
Musical key refers to the tonal center of a piece - the root note and scale that defines its harmonic structure. Knowing a track's key is essential for harmonic mixing, where DJs blend songs in compatible keys for smooth, musical transitions.
Key detection algorithms use pitch analysis to identify the predominant frequencies and harmonic content. By analyzing note frequencies across the audio, the algorithm determines the most likely root note and scale type (major or minor).
The circle of fifths is a fundamental music theory tool showing relationships between keys. Adjacent keys share many common notes, making them ideal for harmonic mixing. Relative major and minor keys (like C major and A minor) also blend naturally.
