Real-time, sound-quality-competitive, single-site from plural-site, anatomical audio signal selection

摘要

A method and apparatus for gathering high-quality anatomical audio signals. Practice of the invention, which is illustrated herein in the context of heart-produced signals, is based upon gathering, and competitively processing audio signals collected simultaneously from two adjacent anatomical sites. Competitive processing examines these two signals in light of certain selected "quality" parameters, and thereby selects the better signal at a user-selected point in time.
