✦ Why BeatDL

🎯
Auto BPM Detection
See the most likely result and top 5 other BPM candidates with corresponding confidence scores.
🎼
Key & Detune Detection
Musical key detected via a Krumhansl-Schmuckler algorithm - maximum accuracy with advanced detune analysis.
⚡
Instant & Private
Runs entirely in your browser - your audio never touches our servers.
Key Candidates
💡 Each row is a relative pair - same key signature, different root. Beats often have different keys in different parts of the song - if the pair you see do not work try the option below.

07/10/2026
BeatDL updated to v1.3! 🚀

You can now see your BPM and key the moment the analysis is done - the file keeps encoding in the background, so results show up about 10 seconds sooner on a typical beat (even more on phones) and the page no longer freezes.

New features

Auto-Tune settingsA new button that tells you exactly how to set Auto-Tune, Pitcher, Melodyne and others for the beat's key and detune - no more guessing.
