   1 Audio-LibSampleRate version 0.002
   2 =================================
   3
   4 Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter for
   5 audio. One example of where such a thing would be useful is converting
   6 audio from the CD sample rate of 44.1kHz to the 48kHz sample rate used
   7 by DAT players.
   8
   9 SRC is capable of arbitrary and time varying conversions ; from
  10 downsampling by a factor of 256 to upsampling by the same factor.
  11 Arbitrary in this case means that the ratio of input and output sample
  12 rates can be an irrational number. The conversion ratio can also vary
  13 with time for speeding up and slowing down effects.
  14
  15 SRC provides a small set of converters to allow quality to be traded
  16 off against computation cost. The current best converter provides a
  17 signal-to-noise ratio of 145dB with -3dB passband extending from DC to
  18 96% of the theoretical best bandwidth for a given pair of input and
  19 output sample rates.
