What BPM/key analysis means
BPM and key help DJs filter and prepare crates, but they still need human checking.
BPM is the approximate tempo of a track, while key is its musical key or Camelot value. These fields help find compatible tracks, build warm-up and peak-time crates, and prepare a set faster. In OroShop, values may come from shared audio analysis or from a user's manual override. The library display prefers your private override when one is saved.
Automatic analysis is not absolute truth. Algorithms can be wrong on beatless intros, live drums, broken rhythms, half-time, or double-time material. A 124 BPM house track can occasionally appear as 62 or 248 BPM if the detector locks onto the wrong grid. Key detection can also be uncertain when a track modulates, contains noisy samples, or only has a short preview.
Use BPM/key as a workflow hint, not as a replacement for listening. Before an important set, verify key transitions in headphones or DJ software. If a value is clearly wrong, save a personal override on the library item. The override changes your library and labels but does not rewrite shared analysis for other users.
When a track has no audio preview, analysis may be missing. Some releases only have external or short shared previews. User audio upload is currently disabled, so you cannot upload your own full file for analysis through the site. This limit reduces storage risk for private audio and keeps MVP privacy boundaries simpler.
