A browser-based tool for analyzing the tempo and estimated key of audio files, individually or in batches.

Landing page captured for the 2026-11-03 issue.

For: DJs, beatmakers, and music-library organizers
Worth noticing: It searches within the selected tempo range and lists relative pulse options, such as 94, 188, and 63 BPM.

Field notes

The interface lists support for MP3, WAV, AIFF, M4A/AAC, FLAC, and OGG, with presets for common music, hip-hop/trap/R&B, house/techno/EDM, and drum & bass/footwork. Its results table includes confidence, key, and Camelot code; the page cautions that key detection is an estimate. The developer-tip link is the only sampled outbound link.
