+Author : Erik de Castro Lopo 
+
+Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter
+for 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 97dB with -3dB passband extending from
+DC to 96% of the theoretical best bandwidth for a given pair of
+input and output sample rates.
