+>Sound on the computer is translated from waves that you hear into a series of
+values, or samples, each representing the amplitude of the wave. When these
+samples are sent in a stream to a sound card, an approximation of the original
+wave can be recreated. The more bits used to represent the amplitude, and the
+greater frequency these samples are gathered, the closer the approximated
+sound is to the original, and the better the quality of sound.</P
+><P
+>This library supports both 8 and 16 bit signed and unsigned sound samples,
+at frequencies ranging from 11025 Hz to 44100 Hz, depending on the
+underlying hardware. If the hardware doesn't support the desired audio
+format or frequency, it can be emulated if desired (See
