Some design issues in digital signal processing for digital-audio systems

Considerations leading to the introduction of the concept of an integrated digital-audio system are presented. Emphasis is placed on its relation to different application areas of digital signal processing. In digital-audio systems some signal processing algorithms can be applied which are unique in the sense that they are related to the acoustic environment. The resulting large signal delays pose problems in the analysis of finite wordlength and overflow effects. For one of the constituing filters of a digital reverberator a design solution is obtained both by calculation and simulation. Some subjective effects are demonstrated at the paper presentation.
