VirtualDJ 5 DJC Edition
analyzing the music files. Since BPM analysis takes a lot of processing time,
mixing while VirtualDJ 5 DJC is analyzing your full library is not recommend as
your computer will not respond as fast as it should.
The analysis is generally perfect but sometimes the BPM rate calculated is not
accurate: sometimes the BPM calculated is double or half of the actual BPM
rate (the BPM analyzer can count only 1 beat out of 2 in a track, or identifies an
intermediary sound inside a beat as the start of another beat). If your file is not
properly analyzed, you can correct it by manually entering the BPM rate.
If a music file is not analyzed, loading the file on a deck analyzes it, and you can
then read its BPM rate on the VirtualDJ skin, above the volume slider.
iii) BPM rate display
The BPM rate is displayed in 2 areas:
- in the file browser, if you have analyzed the files,
- in the mixer area, over the Gain button.
d) Information on music tracks
The text information inserted into each music file is called a "tag": your audio
files are generally tagged automatically when you import an audio CD via
iTunes or Windows Media Player, or when you buy MP3 files. The tag includes
(but is not limited to) the song name, artist name, composer name, album name,
music genre, the date on which the music was recorded, and the BPM.
Once you analyze a music file in VirtualDJ, its BPM rate is added inside the tag.
