cannam@85 66 "Choosing a sample rate coverter wasn't easy. We ran numerous tests with
cannam@85 67 Secret Rabbit Code and other sample rate converters, then compared them all.
cannam@85 68 In the end, SRC outperformed the others, including some extremely well known
cannam@85 69 and popular software. We had one issue with SRC, but after emailing Erik, he
cannam@85 70 got back to us immediately with an answer. Choosing SRC was a no brainer."

cannam@85 80 <B>S</B>ecret <B>R</B>abbit <B>C</B>ode (aka libsamplerate) is a
cannam@85 81 <B>S</B>ample <B>R</B>ate <B>C</B>onverter for audio.
cannam@85 82 One example of where such a thing would be useful is converting audio
cannam@85 83 from the CD sample rate of 44.1kHz to the 48kHz sample rate used by
cannam@85 84 DAT players.

cannam@85 88 <B>SRC</B> is capable of arbitrary and time varying conversions ; from
cannam@85 89 downsampling by a factor of 256 to upsampling by the same factor.
cannam@85 90 Arbitrary in this case means that the ratio of input and output
cannam@85 91 sample rates can be an irrational number.
cannam@85 92 The conversion ratio can also vary with time for speeding up and slowing
cannam@85 93 down effects.

cannam@85 97 <B>SRC</B> provides a small set of converters to allow quality to
cannam@85 98 be traded off against computation cost.
cannam@85 99 The current best converter provides a signal-to-noise ratio of 145dB
cannam@85 100 with -3dB passband extending from DC to 96&#37; of the theoretical
cannam@85 101 best bandwidth for a given pair of input and output sample rates.

cannam@85 105 Since the library has few dependencies beyond that provided by the
cannam@85 106 standard C library, it should compile and work on just about any
cannam@85 107 operating system.
cannam@85 108 It is known to work on Linux, MacOSX,
cannam@85 109 <A HREF="win32.html">Win32</A>
cannam@85 110 and Solaris.
cannam@85 111 With some relatively minor hacking it should also be relatively easy
cannam@85 112 to port it to embedded systems and digital signal processors.

cannam@85 116 In addition, the library comes with a comprehensive test suite which
cannam@85 117 can validate the performance of the library on new platforms.
