The sox resampler library `libsoxr' performs one-dimensional sample-rate conversion - it may be used, for example, to resample pcm-encoded audio.

it aims to give fast and high quality 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.

a simple api is provided that allows interfacing using commonly-used sample formats and buffering schemes.
