Pre-Analysing Your Music Collection
Pre-analysing all your songs at home prior to a gig is strongly recommended.
This will ensure that all songs have the correct gain, BPM, key, song length and the ID3 tags have been read.
In particular, this will avoid the sudden change in volume that can occur when loading an unanalysed song and starting it playing before loading is complete. This is due to the fact that the correct gain setting is not known until the song has been loaded in full.
It will also allow you to see the BPM, song length and key of all your songs in the browser (If you have these columns enabled.) This information is not known to VirtualDJ until the song has been scanned.
The easiest way to pre-analyse your music collection is to do the following:
- Create a new filter folder by clicking the blue + folder icon at the top of the left-hand section of the browser.
- In the Name box, enter: Files to be scanned
- In the Filter box, enter: isscanned=0
- Now when you click on this folder, it will show all files in your database that need analysing.
NOTE: Please ensure that you add all new music to your search database by browsing to the folder where it is located, right-clicking on it and then choosing Add to search DB
- Press CTRL+A on PC or CMD+A on a Mac to select all files.
- Right click on a file (CMD+click on a Mac) and choose Scan for BPMs
This will take some time for a large number of files (You can set it going and leave it, e.g: Overnight.)
You can stop the process at any time and then resume it later by repeating steps 5 and 6.
When you add new music to your database in future, simply add the music to your search database and then repeat steps 5 and 6 to analyse it.
NOTE: If you are using VirtualDJ LE, then this is limited software and does not have filter folders. You will need to upgrade to the full VirtualDJ Professional. There is usually a discount available when upgrading from VirtualDJ LE to the full VirtualDJ professional.
