ripping to a lower quality later. Beyond the Extreme setting, it is very
difficult to tell the difference in sound quality.
Assuming that the average song is 4 minutes long, here is a formula you
can use to estimate the number of GB free disc space needed:
# Songs x 4 min x Size in MB/min x 1 GB/1000 MB
Here is an example to see how much disc space you will need to store
10,000 songs ripped using VBR at the Extreme quality (1.4 MB per
minute) setting:
10,000 x 4 x 1.4 / 1000 = 56 GB
A 500 GB hard drive will hold approximately 70,000 items, assuming 100
GB is needed for Windows, SDJ, and free space. You can use these
formulas to determine how much space you'll need to hold your entire
music collection. The actual space needed depends on the quality of the
items themselves.
Downloading Sound Files
If you don't have any sound files, you can download them from a variety
of web sites. Avoid sound files with DRM (Digital Rights Management).
These files will not play properly in SDJ and many other players.
Licensing can easily be lost, forcing you to buy the music all over again.
