A quick guide to the numbers
Key and scale
These describe the notes that fit the beat. Major, minor, and modes such as Dorian can share the same notes. Possible modes use bass and characteristic-tone evidence; the musical center can still be ambiguous. For a possible mode, Auto-Tune settings use an equivalent major/minor note set. Check the suggestion by singing along.
Hz and cents
440 Hz is the usual reference for A. Cents measure the offset from that reference: 100 cents is one semitone. A negative estimate means the tuning is lower than standard.
Choose a useful section
Start with 20–60 seconds of melody and chords. Drum intros, pitch bends, changing keys, and differently tuned samples can make a single answer unreliable.
This is an experimental estimator. It is not affiliated with Antares or Universal Audio and has not been benchmarked against Auto-Key. Reference tuning is estimated relative to the nearest semitone; the original tuning convention cannot always be inferred from a recording.
