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. + + |
