This paper addresses the issues around switching 1-bit audio streams, such as used in Direct Stream Digital (DSD) in the Super Audio CD format. A theoretical description is derived which shows how these streams can be switched, independent of the Sigma Delta topologies that are used. Also a simplification will be discussed, which is technically much simpler, while still achieving high quality cross-overs between 1-bit audio streams without any audible artifacts.
