smarc: smart audio rate converter
By J. Prado

Smarc is a high quality and fast sample rate converter, based on a multi-stage polyphase structure method.

Smarc is available as a C library which allows high-speed resampling with low memory occupation and can process signals (or files) of arbitrary length. This library is easy to integrate in your application. A sample program shows how to use this library to convert audio wav files.
