AB  - High rate Direct Stream Digital (DSD) is emerging as a format of choice for distribution of high-definition audio content. However, real-time encoding of such streams requires considerable computing resources due to their high sampling rate, constraining implementations to hardware based platforms. In this paper we disclose a new modulator topology allowing for reduction in computational load and making real-time high rate DSD encoding suitable for software based implementation on off-the-shelf Digital Signal Processors (DSPs). We first present the architecture of the proposed modulator and then show results from a practical real-time implementation.
