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. From Antoine Jacoutot <ajacoutot@lphp.org>

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.
