Abstract

A scalable real-time asynchronous sample rate converter software kernel is presented that offers a flexible alternative to the usual hardware implementations. The kernel is dynamically configurable at run-time and supports almost arbitrary upsampling or downsampling ratios and any number of channels. Due to its scalability this sample rate converter kernel may be used both for low complexity, cost-sensitive implementations as well as for top-performance applications. In a typical high peformance application, sample rates of 384kHz are easily achieved on a low cost DSP and DSD input data streams are also supported for compatibilty with SACD.
