This research investigates the physics, psychophysics, and auditory neurophysiology pertaining to high-end audio.
Our psychoacoustic experiments have proven that humans can discern timing alterations on a 5 microsecond time scale, regardless of the highest frequency they can hear.
Other published work has proven that 2-channel stereo is able to reproduce 3D sound, including the controversial dimension of height.
Ongoing work is examining the effectiveness and fallibility of blind testing protocols in the context of how the brain manages auditory short-term memory. This enabled bridging the disparity between anecdotal audiophile reports and published formal research.
Other ongoing work seeks to prove that audio cables do influence sound quality, and seeks to understand the physical reasons for differences in sonic performance.
