Distortion Perception
The GedLee Principals, Earl and Lidia ,are engaged in ongoing research into the correlation
of various
distortion metrics with subjective impression. This research was brought
about by the work we did putting together our first book. In this text a
new paradigm for distortion measurement was proposed that was based on nonlinear systems theory.
This approach is unique in that it is not signal based as all the other
current approaches are.

Early in 2005 an author in England published an article about this work which
was thereby reprinted by Audio Express in the July-August issue of Multi-Media
Manufacturer (www.mutimediamanufacturer,com).
This paper is available here. We then
sent in a letter to the editor as a response.
The AES and SAE Powerpoint
presentation on the new metric is available. Brief results from this study
are also shown on the results
page.
The AES paper on subjective evaluations of compression drivers is
available here.
The 2006 paper on time domain
distortion perception is here.
The 2007 ALMA
China presentation on distortion perception is here.
