  • - TCLH Workshop at 142nd:
  • W3 Perception of Temporal Response and Resolution in Time Domain, Sat. May 20 14:45 - 16:15 Salon 7 Vienna
  • Time response and temporal resolution are controversial topics in sound reproduction. In this workshop a theoretical analysis will be accompanied by the results of listening experiences on the lower end of the audio range and at the higher end. The background is that the temporal relation between the different tones, which make up complex sounds like attacks, need to be conserved to create a viable reproduction of the original sound. Many systems do not preserve a correct time relation (e.g., cross-over filters in loudspeakers, base-reflex systems, and reconstruction filters in digital audio). The aim is to identify the audibility of such timing errors.
  • Participants: Hans van Maanen, Mike Turner, Jan Didden, David Griesinger.
  • New Topics:
  • Attendees are encouraged to raise new topics for discussion.
