Why Precision Matters

Whether you’re a DJ blending tracks in Rekordbox or a producer matching vocal samples, accurate metadata is the difference between a clash and a perfect mix.

DJs: Harmonic Mixing

Use the Camelot system to mix in key. Mixing harmonically ensures seamless transitions. For example, a track in 8A blends perfectly with 7A, 9A, or 8B.

Producers: Sample Matching

Stop guessing the key of your 808s or vocal chops. Upload your samples to find their exact root key instantly, ensuring your bassline matches your melody.

BPM (Tempo) Precision

From 128 BPM Techno to 174 BPM DnB. Our algorithm locks onto transients to give you a precise tempo reading, even with complex breakbeats.

AI-Powered Analysis

We analyze harmonic content and transient data using machine learning to estimate key, tempo, Camelot code, and energy levels in seconds.

Understanding Audio Metrics

Danceability Score

How suitable is a track for the club? We analyze beat strength and rhythm stability.

  • Low (< 0.33): Ambient, Drone, Intro tools.
  • Mid (0.33 - 0.66): Lo-Fi, Pop, Downtempo.
  • High (> 0.66): House, Techno, Club Bangers.

Energy & Mood

Energy measures intensity (loudness, noise, speed). Mood (Valence) measures musical positivity.

  • High Energy: Peak-hour tracks, Dubstep, Hardstyle.
  • High Happiness: Major keys, Uplifting Trance, Disco.
  • Low Happiness: Dark Techno, Melancholic Piano.

Harmonic Mixing Guide

The Camelot Wheel simplifies harmonic mixing. To mix smoothly, move one step Hour-wise, Counter-Clockwise, or switch between Inner/Outer rings.
