Notes

Any additional information about the SoundSeed Wind plug-in.

Effect Settings

Deflectors

Objects that are placed within a scene that interact with the wind using a series of deflector properties.

ID

The identification number assigned to the deflector.

[M]

Silences the corresponding deflector. This can facilitate the authoring of the wind scene.

It is possible to have more than one deflector muted at the same time. All deflectors will be rendered by Wwise regardless of whether a deflector is muted or not.

[S]

Mutes other deflectors so that the chosen deflector can be auditioned alone. This can facilitate the authoring of the wind scene.

It is possible to have more than one deflector soloed at the same time. All deflectors will be rendered by Wwise regardless of whether a deflector is soloed or not.

To solo a single deflector when other deflectors are already soloed, simply Ctrl+click the solo button. This will select the current Solo button and clear all other Solo buttons that are already selected.

Frequency

The deflector’s resonant center frequency when exposed to wind at a medium velocity.

The Frequency value defines the size of the deflector circle in the Deflector Positions graph view.

Default value: 440
Range: 20 to 20000
Units: Hz

Q Factor

The peakiness or sharpness of the deflector’s resonance curve. Q factor is inversely related to bandwidth, so a large Q factor results in a narrow bandwidth and a small Q factor results in a wide bandwidth.

A high Q factor value should be used to simulate regular or round surfaces, whereas a low Q factor value should be used to simulate irregular surfaces.

Default value: 10.0
Range: 0.1 to 50

Gain

The amount by which the deflector’s signal will be amplified. Increasing this value “boosts” the deflector signal. Decreasing this value “cuts” or attenuates the deflector signal.

The gain value also defines the color of the deflector circle in the Deflector Positions graph view. A dark gray color corresponds to a high gain value, whereas a light gray color corresponds to a low gain value.

Default value: 0
Range: -24 to 24
Units: dB

 

Adds a new deflector in the Deflectors list and creates a deflector object in the Deflector Positions graph view.

You can also create a new deflector by double-clicking anywhere in the Deflector Positions graph view.

Deletes the selected deflector from the Deflectors list and the Deflector Positions graph view.

Deflector Positions

(Graph View)

A graphical representation of the location of the deflectors in relation to the speakers in a 4.0 environment.

To position a deflector within the graph view, simply click its inner circle and then drag it to the new location.

Zooms in towards the center of the graph view.

Resets the graph view to the default zoom factor ratio of 1:1.

Zooms out from the center of the graph view.

X

The coordinate along the X axis of the deflector. The X value is measured as a percentage of the maximum distance value.

Y

The coordinate along the Y axis of the deflector. The Y value is measured as a percentage of the maximum distance value.

Maximum Distance

Defines the maximum dimensions of the wind scene.

The maximum distance is represented in the graph view by the outer circle. Since the outer circle is fixed in place, when you change the maximum distance value, the minimum distance circle will be resized accordingly.

Although the deflectors in your scene do not appear to move when modifying the Maximum distance value, their positions are actually scaled in relation to the maximum distance value.

Default value: 10.0
Range: 1.0 to 100.0

Properties

(Pin/Unpin)

Determines whether a property curve will remain in the graph view when another curve is selected.

When the Pin icon is selected, the curve will be displayed in the graph view whether the curve is selected or not.

(Color block)

Displays the color of the corresponding property curve in the graph view.

Wind Speed

The average velocity of the wind. Wind speed is interpreted in terms of an offset in pitch applied to the deflectors in a scene.

Default value: 0
Range: -2400 to 2400

Direction

The direction from which the wind originates.

The degrees are mapped to the following directions:

  • 0 degrees - North (front)
  • 90 degrees - East (right)
  • 180 or -180 degrees - South (back)
  • -90 degrees - West (left)

Default value: 0
Range: -180 to 180

Variability

The amount by which the wind speed can change due to wind gusts.

SoundSeed Wind yields optimal results when property values evolve slowly. As a result, using high variability values in combination with high gustiness and Q factor values will most likely produce undesirable results.

Default value: 0.25
Range: 0.0 to 1.0

Gustiness

The likelihood that the wind speed will change over time.

Default value: 0.5
Range: 0.0 to 1.0

Frequency Shift

A global property that defines the amount by which all deflectors’ center frequencies have been shifted up or down.

Default value: 0.0
Range: -4.0 to 4.0

Q Factor Shift

A global property that defines the amount by which all deflectors’ Q factors have been shifted up or down.

Default value: 0.0
Range: -4.0 to 4.0

Gain Offset

A global property that defines the amount by which all deflectors’ gain is offset. This property can be used as a master gain control.

Default value: 0.0
Range: -96.3 to 24.0
Units: dB

Value

The specific numerical value assigned to the corresponding property.

Random

A positive and negative offset applied to the corresponding property value that defines a range of possible values for the property. For example, adding a random value of 1 to a property value would mean that the possible range for that property would be [(value - 1) to (value +1)].

When defining a Random value, Wwise randomly selects a value from within the range (value +/- random) each time the wind sound is played.

Default value: 0.0
Range: 0.0 to 3600.0

Automate

Automates the values of the property over the duration of the sound using automation curves.

When this option is selected, you can edit the automation curve for the corresponding property in the graph view.

Default value: false

Time

Duration

The length in seconds of the wind sound source.

You can create an infinitely looping wind sound by setting the Loop property to Infinite for the parent sound object.

Default value: 10.0
Range: 0.1 to 3600.0

Duration random

An positive and negative offset applied to the Duration property value that defines a range of possible values. For example, if you have the Duration set to 10 and the Duration random set 5, this would mean that the possible range for the Duration would be (5 to 15) or [(Duration value - 5) to (Duration value +5)].

When you define a Duration random value, Wwise will randomly select a value from within the range (value +/- random) each time the wind sound is played. For looping sounds, every iteration will have a randomized duration.

Playback rate

A factor applied to the duration property value that determines the rate at which the wind sound is played back. For example, a value of 2 will render the synthesized sound 2 times faster, which makes the sound twice as short.

This option can be useful when you want the automation curve to be read at dynamic rates which follow a Game Parameter that the game cycles through at a variable speed. For example, imagine that a character in the game takes a potion which slows down time by a factor of two; then, cycling through automation curves with a playback rate of 0.5 would keep all air sounds in sync with the game’s time flow.

Default value: 1.0
Range: 0.1 to 10.0

 

(Graph View)

A graphical representation of the property value automation curve, where the X axis represents the duration of the sound and the Y axis represents an offset to the original property value.

Only curves with the Automate option selected can be edited in the graph view. You can move points along the curve by clicking and dragging. To add a point, double-click anywhere along the curve. Right-click on a section of the curve to select a different curve shape.

If RTPCs are applied to automated property values, Wwise will combine the property values defined in the automation curve with those in the RTPC curve.

The graph view can display several curves simultaneously by selecting multiple properties in the list or by using the pin option.

Zooms in towards the center of the graph view.

Resets the graph view to the default zoom factor ratio of 1:1.

Zooms out from the center of the graph view.

 

X

The coordinate along the X axis of the selected control point.

If more than one control point is selected, the field displays a value of 0, so that you can increase or decrease the value of all selected control points relative to their current values. For example, if you select two control points and type -5 in the X text box, both control points will move to the left by 5 units.

Y

The coordinate along the Y axis of the selected control point.

If more than one control point is selected, the field displays a value of 0, so that you can increase or decrease the value of all selected control points relative to their current values. For example, if you select two control points and type -5 in the Y text box, both control points will move down by 5 units.

Attenuation

Minimum Distance

The distance from the center of the scene where no attenuation gain is applied (0 dB). This property is measured as a percentage of the scene.

For more information about the attenuation model used by SoundSeed Woosh, refer to Wwise SoundSeed Air - Woosh .

Default value: 10
Range: 1 to 100

Roll-off Factor

Specifies the slope of the attenuation curve, where higher values produce steeper slopes or faster attenuation.

At a value of 1, a -6 dB attenuation is applied each time the deflector’s distance is doubled after the Minimum distance. A roll-off of 2 creates a steeper slope that attenuates the deflector twice as fast. A roll-off of 0.5, on the other hand, creates a flatter slope that attenuates the deflector two times slower.

For more information about the attenuation model used by SoundSeed Wind, refer to Wwise SoundSeed Air - Wind .

Default value: 1
Range: 0.0 to 4

Settings

Dynamic range

Determines the dynamic range or the ratio between the highest and lowest levels in the wind signal that can result from changes in wind speed.

Smaller values result in a compressed dynamic range, which means that changes in wind speed will have a smaller impact on level changes. For the same change in wind speed, larger values will result in a wider range of levels in the wind signal.

Default value: 0.5
Range: 0 to 1

Channels

The channel output configuration. You can select any of the following options:

  • 1.0 - Outputs in mono with no spatialization.
  • 2.0 - Outputs in stereo with left-right spatialization.
  • 4.0 - Outputs in 4.0 with surround spatialization.

Default value: 2.0
Units: °
