Abstract
An in-line filter uses scalar coils positioned in series with an input of a speaker to modify or enhance the audio quality and of the speaker, and its auditory effects on a user, by changing the sound signature and reducing digital noise. Scalar coils have two spiral windings with opposite winding directions. Scalar coils can also be used in series with a laser emitter that produces a laser beam that travels through the scalar coil, which produce electromagnetic forces that improve perceived audio quality in a user.
