Residual Extraction and Resynthesis

Once the modes of a system (or sound) have been identified, they can be removed fi om the sound by various methods. Modes are associated with filter poles, so antimodes can be modeled by complementary zeroes. Constructing an all-zero filter and passing a modal sound through it yields a residue, or residual, which is that part of the sound left over after the modes are removed. 

A wide variety of sounds can be synthesized using modal synthesis. Any object which exhibits a few modes and is excited by striking or plucking is a likely candidate for modal modeling. Such objects might include metal pots and pans, glasses, etc. Modal synthesis can also work well for simple wooden objects such as blocks, boards, etc.
