help KeyFinder FAQ

What does KeyFinder actually detect in a music file?

KeyFinder analyzes digital audio files and reports their musical key, typically using Camelot Wheel notation that DJs use for harmonic mixing. This helps DJs identify which tracks will mix harmonically with each other during live sets.

Is KeyFinder free to download?

KeyFinder, developed by Ibrahim Sha'ath, is available as a free download for both macOS and Windows. It is open source, which has made it a popular no-cost alternative to paid key detection tools like Mixed In Key.

Can KeyFinder write detected keys directly into my DJ library metadata?

Yes, KeyFinder writes the detected key information directly into the ID3 metadata tags of your audio files. This means software like Serato, Rekordbox, and Traktor can read the key tags when you import your library, integrating seamlessly into existing DJ workflows.

How accurate is KeyFinder compared to Mixed In Key?

KeyFinder is generally regarded as a reliable free tool for harmonic key detection, though some DJs consider Mixed In Key to have a slight edge in accuracy and additional features like energy level reporting. For most practical DJ mixing purposes, KeyFinder provides dependable results.
