The property page provides a user interface for changing the filter's attributes.effect. Changes will be applied directly to the streaming media with the ability to set them permanently by selecting Apply or OK, or to abandon changes by selecting Cancel. Positioning the mouse pointer over a control displays general information for that control. The following table shows the controls and their descriptions:

Control	Description
Enable check box	Enables/Disables the effect.
Combine check box	If selected, preserves the difference between the wet and dry mixes.
Wet mix % slider	Controls the level of processed signals. Adjust to control the pass-through volume of the processed signal.
Dry mix % slider	Controls the level of unprocessed signals. Adjust to control the pass-through volume of the unprocessed signal.
Feedback % slider	Controls the feedback of the repeated signal, by default from -100 to 100. Zero feedback will result in only a single repeat, while nonzero feedback settings will generate numerous repeats.
Delay slider	Controls the level of flange effect: larger values result in greater delay times.
Stereo slider	Controls the phase difference between the left and right channel.
Rate slider	Controls the rate at which the LFO waveform repeats itself. By increasing the speed, the flanger will have to sweep through the depth in less time.
Sweep slider	Controls how wide the sweep is in terms of delay time - essentially the width of the LFO. This sweep depth is the maximum additional delay that is added to the signal in addition to the delay in the delay parameter.
Default button	Restores properties to their default values.
Set as Default button	Saves the current property values as the default values.
