The present invention provides a device for occluding an anatomical aperture, such as an atrial septal defect or a patent foramen ovale. The cured in place pipe system forms a completely rehabilitated, stand-alone, fluid-tight flow path between upstream and downstream portions of an existing pipe system. Each channel processing unit of the at least two channel processing units is configured to generate one or more of at least two processed channels depending on side information and depending on one or more of the three or more downmix channels received by the channel processing unit from the input channel router.
