libsamplerate: Secret Rabbit Code (aka libsamplerate)
libsamplerate:
libsamplerate: SRC is capable of arbitrary and time varying conversions;
libsamplerate: from downsampling by a factor of 12 to upsampling by the same factor.
libsamplerate: Arbitrary in this case means that the ratio of input and output sample
libsamplerate: rates can be an irrational number. The conversion ratio can also vary
libsamplerate: with time for speeding up and slowing down effects.SRC provides a small
libsamplerate: set of converters to allow quality to be traded off against computation
libsamplerate: cost. The current best converter provides a signal-to-noise ratio of 97dB
libsamplerate: with -3dB passband extending from DC to 96% of the theoretical best
libsamplerate: bandwidth for a given pair of input and output sample rates.
