1. The Effect plugins I have used are
Ambient, RealFir and Dub Delay to
change the sound.
The Parameter I changed on the ambient plugin was change the
preset from Papen bright and long to Pady-Drums Gated and then
moved the ambience dials in different directions.
The parameter I changed on the RealFir plugin was move the point
up and down to change loudness and pitch and also increased the
output gain.
The parameters I change on the Dub Delay plugin was turn the dial in
different direction and activated the buttons to apply additional
Effects to the sound
The original sounded of a chair being
scraped across the floor and it now
sounds like radar on a submarine
