Abstract
The paper presents two new approaches to artefact-free real-time updates of the impulse
response in convolution. Both approaches are based on incremental updates of the filter. This can
be useful for several applications within digital audio processing: parametrisation of convolution
reverbs, dynamic filters, and live convolution. The development of these techniques has been done
within the framework of a research project on crossadaptive audio processing methods for live
performance. Our main motivation has thus been live convolution, where the signals from two
music performers are convolved with each other, allowing the musicians to “play through each
other’s sound”.
