The BPM Engine analyzes the audio to determine the tempo of the track. Analyzing a track can be
performed 2 ways – Load the track to a deck or right-click on the track in the Brower panel and select
BPM -> Re-Analyze. You can also analyze a group of tracks contained in a folder from the left
Navigation panel, right-click on the folder and select Scan for BPMs.
If the tracks have been analyzed by an external application prior to being loaded into VirtualDJ and that
value is stored in the BPM tag, the BPM Engine will use the stored value as a reference when
analyzing the track. VirtualDJ will calculate a more precise value to a 0.05 BPM precision not more than
+/- 1 beat per minute away from the value of the tag.
Part of the BPM Engine is also a Key Detection Engine. Determining the ‘musical key’ of a track
provides the ability to harmonically mix tracks. The Key Detection Engine strongly favors minor keys,
as most studio production songs are in minor key. But if the key is strongly major, it will be reported as
a major key.
If you wish to manually ‘tap-out’ the beats per minute of a song, you can left-click to the beat on the
BPM button of the appropriate deck playing your track. If you would like to assign a keyboard shortcut
or assign a button on a controller, the mapping action beat_tap action can be assigned.
Last, if the BPM (or the Key) is manually entered using the File Info dialog, then VirtualDJ will use the
entered value and will not analyze the BPM or Key. If forced by selecting the BPM -> Re-Analyze
function the track is re-analyzed without regard to existing data or how the data was entered.
Part of VirtualDJ’s BPM Engine is to calculate the Computer Beat Grid (CBG) of the track. The
computer beat grid is a 4/4 beat measure indicator for identifying the timing gap of the track. This
becomes helpful when manually beat mixing a track or using VirtualDJ’s synchronized play (SYNC),
Beat Lock, or Automix Tempo Mix features.
Adjusting the BPM and CBG:
In rare cases, when the BPM and the CBG is not correctly calculated, you can easily correct both
manually by right-clicking on the appropriate BPM button of the appropriate deck for the track.
