Questions
Does Key Detector upload my song?
No. The file is decoded and analyzed locally in your browser tab. Utilumo does not upload or store the audio.
What is Camelot notation?
Camelot notation maps musical keys to DJ-friendly codes, such as 11A for F# Minor and 11B for A Major.
Can key detection be wrong?
Yes. Key estimates are probabilistic, especially with key changes, sparse audio, unusual tuning, or ambiguous major/minor harmony.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
