Controlling the Balance Between Early and Late Reflections of an Impulse Response Using the Modal Decomposition Paradigm

Document Thumbnail

Previous work has outlined a method of decomposing an acoustic impulse response (IR) into decaying sine components, which allows for parametrization of a modelled IR. This enables control over a convolution based reverberator akin to an algorithmic reverberator. A common control found in an algorithmic reverb is the balance between early and late reflections. This work introduces a method of adjusting the balance between early and late reflections without direct processing of the impulse response, through a component domain transform. This work extends the creative applications of indirect IR Processing through the use of the modal decomposition paradigm.
