The document discusses audio effects used in a VST, including setting the 'Wown Flutter' effect to 'Wornout Walkman' mode and raising the minimum level coarse setting to 1.07 to add distortion without making the audio too difficult to understand. Ambience was used for a slight echo effect and other plugins adjusted the volume and clarity. Wown Flutter was applied to simulate the distorting effect of a mask on a character's voice.
