+ "Choosing a sample rate coverter wasn't easy. We ran numerous tests with
+ Secret Rabbit Code and other sample rate converters, then compared them all.
+ In the end, SRC outperformed the others, including some extremely well known
+ and popular software. We had one issue with SRC, but after emailing Erik, he
+ got back to us immediately with an answer. Choosing SRC was a no brainer."

+ <B>S</B>ecret <B>R</B>abbit <B>C</B>ode (aka libsamplerate) is a
+ <B>S</B>ample <B>R</B>ate <B>C</B>onverter 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.

+ <B>SRC</B> 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.
+</P>
+<!-- pepper -->
+<P>
+ <B>SRC</B> 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.

+ Since the library has few dependencies beyond that provided by the
+ standard C library, it should compile and work on just about any
+ operating system.
+ It is known to work on Linux, MacOSX,
+ <A HREF="win32.html">Win32</A>
+ and Solaris.
+ With some relatively minor hacking it should also be relatively easy
+ to port it to embedded systems and digital signal processors.
+</P>
+<!-- pepper -->
+<P>
+ In addition, the library comes with a comprehensive test suite which
+ can validate the performance of the library on new platforms.
