Claim Text:
1. A system for enhancing reproduction of sound, comprising a parametric binaural module filter for transforming a first electromagnetic audio signal to a second electromagnetic audio signal, where: the parametric binaural module filter comprises one or more of a sum filter and a cross filter; and the sum filter and the cross filter are derived from one or more known direct head-related transfer functions and one or more known indirect head-related transfer functions; where the derivation of the sum filter and the cross filter are from a processor configured to transform the one or more known direct head-related transfer functions and the one or more known indirect head-related transfer functions to one or more sum transfer functions and one or more cross transfer functions; where the processor configured to transform the one or more known direct head-related transfer functions and the one or more known indirect head-related transfer functions to the one or more sum transfer functions and the one or more cross transfer functions is further configured to: a switch to select various sets of the one or more parameters that are common to the one of more sum transfer functions and the one of more cross transfer functions, where the processor configured to transform the one or more known direct head-related transfer functions and the one or more known indirect head-related transfer functions to the one or more sum transfer functions and the one or more cross transfer functions is further configured to:
