Audio Processing with Adaptive Computational Costs

Audio processing applications can and do suffer from overload situations. This results in unwanted sound events: strong distortions, clicks and interruptions. For practical reason it is not always possible to resolve such problems always with more computational ressources. In this talk we will present ideas which try to take another approach. We want to flexibilise the computational costs of the elements of the audio processing chain to control them dynamically thus avoiding overload situations of the system. This flexibilization is realized by means of a trade-off between computational costs and the quality of the audio output.

In this seminar we will present an introduction to the subject as well as our first ideas and some preliminary proposals of our research.
