It aims to give fast¹ and very high quality² results for any constant
(rational or irrational) resampling ratio. Phase-response, preserved
bandwidth, aliasing, and rejection level parameters are all configurable;
alternatively, simple `preset' configurations may be selected. An
experimental, variable-rate resampling mode of operation is also included.

The resampler is currently available either as part of `libsox' (the audio
file-format and effect library), or stand-alone as `libsoxr' (this package).
