Abstract

We describe an asynchronous sampling-rate conversion (SRC) algorithm that is specifically tailored to multi-channel audio applications. The algorithm is capable of converting between arbitrary asynchronous sampling rates around a fixed operating point, and it is designed to operate in multi-threaded systems. The algorithm uses a set of fractional delay filters together with cubic interpolation to achieve accurate and efficient sampling-rate conversion.
