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 12 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.
