Abstract
Official abstract text for this publication.
A sound enhancement system (SES) that can enhance reproduction of sound emitted by headphones and other sound systems. The SES improves sound reproduction by simulating a desired sound system without including unwanted artifacts typically associated with simulations of sound systems. The SES facilitates such improvements by transforming sound system outputs through a set of one or more sum and cross filters, where such filters have been derived from a database of known direct and indirect head-related transfer functions (HRTFs).
First claim
Opening claim text (preview).
I claim: 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;…
