+one standard library interface.
+
+It was designed to handle both little-endian (such as WAV) and
+big-endian (such as AIFF) data, and to compile and run correctly on
+little-endian (such as Intel and DEC/Compaq Alpha) processor systems as well
+as big-endian processor systems such as Motorola 68k, Power PC, MIPS and
+SPARC.  Hopefully the design of the library will also make it easy to extend
+for reading and writing new sound file formats.")

+audio.  One example of where such a thing would be useful is converting audio
+from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT
+players.
+
+SRC is capable of arbitrary and time varying conversions; from downsampling by
+a factor of 256 to upsampling by the same factor.  Arbitrary in this case means
+that the ratio of input and output sample rates can be an irrational
+number.  The conversion ratio can also vary with time for speeding up and
+slowing down effects.
+
+SRC provides a small set of converters to allow quality to be traded off
+against computation cost.  The current best converter provides a
+signal-to-noise ratio of 145dB with -3dB passband extending from DC to 96% of
+the theoretical best bandwidth for a given pair of input and output sample
+rates. ")
