Sample WinSound Analyses

Will Spicher

These analyses serve as examples on the use of WinSound as well as starting points for learning how to create models.

Hot-Spot Reduction Analysis
for Faith Christian Centre
November, 2000

This analysis identifies high levels in the front rows and concludes that the major reason is the low levels received at the mixing position. However, because moving the board was not an option at the time, the recommendation is a split-cluster configuration.

This is the basic intent for WinSound--answering the question, where is the sound going?  It includes

WinSound model of current FCC system.
WinSound model of proposed split-cluster system.

Intelligibility Improvement Analysis
for Cherry Creek Community Church
June, 2001

This analysis uses WinSound to investigate an intelligibility problem with a reverberant room.
WinSound model of current system.
WinSound model of proposed system.

Ceiling Reflection Analysis
for Faith Christian Centre
June, 2001

This analysis uses WinSound to model the first reflection from the ceiling directly behind the cluster.  It verifies that this reflection is an important contributor to observed amplification at upper-bass frequencies.

Wait! I thought WinSound doesn't model reflections.
It doesn't.  However, a creative user running WinSound (with a little blood, sweat, and tears) can actually use WinSound to cobble together a crude investigation of a reflection problem.
