This research investigates the physics, psychophysics, and auditory neurophysiology pertaining to high-end audio. Some results are:
Psychoacoustic experiments proving humans can discern timing alterations on a 5 microsecond time scale, regardless of the highest frequency they can hear.
Psychoacoustic experiments proving 2-channel stereo is able to reproduce 3D sound, including the controversial dimension of height.
Psychoacoustic experiments proving cable pathways can be audibly distinguished through blind tests of sufficient duration to invoke the more fine grained long-term memory rather than the coarser short-term memory.
An electrical investigation of analog interconnects to explore parameters and distortions beyond the traditional frequency response and resistance, inductance, and capacitance.
Ongoing work is investigating the information resolution capabilities of the human auditory system through a deeper understanding of its neurophysiology.
