Using uncompressed drum samples is actually the domain of those

that can spot the potential in samples. Rarely

do thin ears spot this potential, and this is the reason why over-

compressed sounds are peddled by most rap music production internet

sites, and successfully so, I would add. Compression

is basically the process of

accelerating the volume of the quiet parts of a sound sample so that the

gap between the highs and lows (

in terms of volume ) is lessened.
Compression on drum samples can come into your workflow at two stages.

The first is the drum sample selection process. This is where you

will find the examples that were suitably

compressed by the library manufacturer, and hopefully not excessively compressed.
One of a few compression techniques for

drum samples is the NY compression effect.

Basically, it's attained by combining an original

sample with the same sample heavily compressed. Having both permits

the volume to be maximized while the dynamics aren't absolutely reduced.
