Question 1

How do I find the key of a song?

Accepted Answer

Upload your audio file (MP3, WAV, FLAC, M4A, OGG, or AIFF) to the Key Finder. The AI analyzes the chromagram (pitch-class energy distribution) and reports the detected key, mode (major/minor), Camelot notation, and confidence score — usually in under 10 seconds.

Question 2

What is the Camelot Wheel and why do DJs use it?

Accepted Answer

The Camelot Wheel maps the 24 musical keys onto a clock-face notation (1A–12A for minor, 1B–12B for major) where adjacent positions are harmonically compatible. Mixing tracks with the same Camelot code, ±1 position, or relative major/minor (same number, opposite letter) sounds smooth and musical.

Question 3

How accurate is AI key detection?

Accepted Answer

On tonal material with a clear tonic (most pop, rock, hip-hop, electronic), accuracy exceeds 90%. For modal music, jazz with frequent modulation, or atonal passages, the algorithm reports lower confidence and offers a second-best candidate — far more useful than tools that always commit to a single answer.

Question 4

Can it detect key changes within a song?

Accepted Answer

Yes. The per-section key map analyzes the chromagram across the timeline so you can see modulations — for example, a chorus that lifts to the relative major, or a bridge in a parallel minor. This is essential for sampling, remixing, or writing backing parts.

Question 5

Is the key finder free?

Accepted Answer

Yes. The Key Finder is included in the Audio Analysis suite, free with a Mixing & Mastering AI account. Free accounts include monthly analysis quota; paid plans process unlimited files. No credit card needed to try it.

Question 6

What is the difference between musical key and Camelot notation?

Accepted Answer

They are the same information in different formats. Musical key (e.g. “A minor”) tells musicians what scale and chords to play. Camelot notation (e.g. “8A”) tells DJs which other tracks will mix harmonically — adjacent Camelot codes share most notes, so transitions sound smooth instead of dissonant.
