What formats are included in the downloaded archive?

The ZIP package includes collection.nml for Traktor, rekordbox.xml, cue_points.cue for CDRWIN/burners, CSV, JSON, and an import README.

How are cue points aligned to the music?

Detected structural novelties are aligned and snapped to a 4-bar grid based on peak RMS novelty and energy salience.

What semantic cue types does the detector identify?

It identifies the mix-in (initial energy entry), drop (bass surge after a build), breakdown (bass withdrawal with ongoing harmony), and mix-out points.

What is the maximum audio file size supported?

You can upload audio files up to 100 MB.

Should I verify the cues before performing live?

Yes, automated cue points serve as a structural starting point and should always be auditioned prior to a live gig.

DJ Cue Point Detector

Detect mix-in, drop, breakdown, and mix-out cue points in a music track and export them for Traktor, rekordbox, and CD burners.

Details

What this tool helps you do

A structure-analysis cue finder that follows the published DJ-switch-point method: beat-synchronous energy/bass/brightness/chroma/onset features build per-feature self-similarity matrices, a Gaussian checkerboard kernel (Foote) produces novelty curves, peaks above 0.3x of each feature max are snapped to the 4-bar period grid (phase by max RMS novelty), then filtered by salience (the 4 bars after a cue must carry real energy). Semantic rules label the mix-in (first energetic grid point), the drop (bass jumps in after a quiet build), the breakdown (bass falls away while harmony continues), and the mix-out (last energetic point in the tail). The ZIP contains collection.nml (Traktor), rekordbox.xml, cue_points.cue (CDRWIN 75 fps), CSV, JSON, and an import README. Cues are a starting point — always audition them before a gig.
