libsamplerate currently provides three different sample rate conversion algorithms; zero order hold, linear interpolation and FIR filter interpolation (using filters derived from the mathematical SINC function). The first two algorithms (zero order hold and linear) are included for completeness and are not recommended for any application where high quality sample rate conversion is required. For the FIR/Sinc algorithm, three converters are provided; SRC_SINC_FASTEST, SRC_SINC_MEDIUM_QUALITY and SRC_SINC_BEST_QUALITY to allow a trade off between conversion speed and conversion quality.
libsamplerate is capable of downsampling to 1/256 of the original sample rate and upsampling to 256 times the original sample rate. It is also capable of time varying conversions for vary speed effects and synchronising of two unlocked sample rates.
