AB  - The utility of directly processing sigma-delta encoded audio signals is discussed. The problems of overflow and rounding in such a system and the consequential noise build-up are investigated. An efficient and cost-effective method of implementing a second-order filter, given the higher sample rate, is presented. The problems of coefficient accuracy are also discussed.
