MP3 · WAV · FLAC · AIFF · M4AWhat is key detection?
Every piece of music sits in a key — the harmonic center. Knowing it lets you mix tracks that won't clash, choose samples that fit, and write melodies on top.
Key detection analyzes the spectral content of a recording, builds a 12-bin chromagram of pitch class energies, and matches it against profiles for each of the 24 major/minor keys.
How to use
- Drop an audio file (MP3, WAV, FLAC, AIFF, M4A) onto the dropzone, or click to browse.
- Analysis runs in your browser — nothing is uploaded.
- The result shows the detected key in standard, Camelot, and Open Key notations.
Privacy
Audio files are processed locally via the Web Audio API. They never leave your device, never hit a server, never get stored.
Accuracy
Key detection is reliable on tonal material (vocals, melodic instruments, harmonic content). It's less reliable on heavily atonal or beat-only tracks. Always verify by ear.
