TagWave — Built for people who live music.
TagWave detects musical key with precision beyond Rekordbox and Serato, classifies every track by energy and mood, organizes your library into dynamic crates — and syncs everything to Serato, Rekordbox and Engine DJ in one click. The complete alternative to Mixed In Key and Lexicon DJ — one tool for key/BPM analysis and library management — for DJs and producers on macOS and Windows.
TagWave is DJ library management built for your DJ workflow — Serato organization, Rekordbox playlists and Engine DJ sync, with clean music metadata (key, BPM, mood, genre) enriched from MusicBrainz, Spotify and Apple Music.
Why TagWave instead of Mixed In Key or Lexicon
- vs Mixed In Key: Mixed In Key only analyzes (key, BPM, energy). TagWave analyzes and manages — dynamic crates, batch tagging, duplicate detection and one-click sync to your DJ software. And Mixed In Key charges again for every major version (MIK 10 owners paid again for MIK 11); TagWave Lifetime includes two years of updates and never stops working.
- vs Lexicon: Lexicon organizes your library but relies on external analysis. TagWave does its own key/BPM/mood detection and the library engine in a single native app — no subscription lock-in required, with a one-time Lifetime option.
- Try before you pay: 14-day free trial with everything unlocked, no credit card. If you don't subscribe, you keep a free mode to view and organize.
What TagWave does
- Sub-beat BPM & key detection on every track, written as a consistent ID3v2.4 tag block with album art.
- Automatic metadata — pulls and cross-checks key, BPM, genre, album, year and cover from MusicBrainz, Spotify and iTunes.
- Audio-fingerprint duplicate detection — finds the same track at different bitrates and merges it.
- One naming convention for your whole library, applied in seconds.
- One-click sync to Serato, Rekordbox and Engine DJ, preserving cue points, hot cues and beatgrids.

Frequently asked questions
- What is TagWave? A DJ library engine that detects key, BPM, mood and energy, organizes tracks into dynamic crates and syncs to your DJ software.
- What formats are supported? MP3, AIFF, WAV, FLAC, ALAC, AAC and OGG.
- Is there a cloud component? Where does my data go? Everything runs locally. Metadata lookups are anonymous HTTPS calls — no library upload.
- Will it overwrite my Rekordbox cue points? No. Sync preserves cue points, hot cues, beatgrids and key-lock.
- Does it work with older versions of Serato, Rekordbox or Engine DJ? Yes — Serato DJ Pro 2.x–4.x, rekordbox 6 and 7, and Engine DJ 2.x–3.x. Older releases may need an update, and TagWave warns you instead of failing silently.
