Abstract
Embodiments of the invention include methods, systems and computer program products for generating at least one control parameter for controlling a signal processor that processes audio signals. A point set is defined, wherein the point set may assume a plurality of topological configurations. Each topological configuration comprises at least one region, each of the at least one region associated with at least one or more topological attributes. A mapping is defined from each of the plurality of topological configurations to a respective plurality of parameters, wherein the mapping is performed based upon the topological attributes of said topological configuration. A user input is received wherein the user input expresses a transformation of the point set from a first topological configuration a second topological configuration. An updated set of topological attributes is determined based upon the second topological configuration. The one or more control parameters are updated based upon the second topological configuration using the mapping.
