  65 sampled sound (such as MS Windows WAV and the Apple/SGI AIFF format) through
  66 one standard library interface.
  67
  68 It was designed to handle both little-endian (such as WAV) and
  69 big-endian (such as AIFF) data, and to compile and run correctly on
  70 little-endian (such as Intel and DEC/Compaq Alpha) processor systems as well
  71 as big-endian processor systems such as Motorola 68k, Power PC, MIPS and
  72 SPARC.  Hopefully the design of the library will also make it easy to extend
  73 for reading and writing new sound file formats.")

  95      "Secret Rabbit Code (aka. libsamplerate) is a Sample Rate Converter for
  96 audio.  One example of where such a thing would be useful is converting audio
  97 from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT
  98 players.
  99
 100 SRC is capable of arbitrary and time varying conversions; from downsampling by
 101 a factor of 256 to upsampling by the same factor.  Arbitrary in this case means
 102 that the ratio of input and output sample rates can be an irrational
 103 number.  The conversion ratio can also vary with time for speeding up and
 104 slowing down effects.
 105
 106 SRC provides a small set of converters to allow quality to be traded off
 107 against computation cost.  The current best converter provides a
 108 signal-to-noise ratio of 145dB with -3dB passband extending from DC to 96% of
 109 the theoretical best bandwidth for a given pair of input and output sample
 110 rates. ")
