Property Editor: Audio Bus

This Property Editor contains the properties for the selected Audio Bus. You can adjust the overall Volume, Pitch, Low-pass filter and High-pass filter, as well as duck the audio signal of other busses when the current bus is receiving a signal.

General

Interface Element

Description

Name

The name of the object.

Notes

Any additional information about the object properties.

Controls the Mute and Solo states for the object and shows the implicit mute and solo states for the object.

Muting an object silences this object for the current monitoring session. Soloing an object silences all the other objects in the project except this one.

A bold M or S indicates that the Mute or Solo state has been explicitly set for the object. A non-bold M or S with faded color indicates that the object's Mute or Solo state was implicitly set from another object's state.

Muting an object implicitly mutes the descendant objects.

Soloing an object implicitly mutes the sibling objects and implicitly solos the descendant and ancestor objects.

[Tip] Tip

Hold the Ctrl key while clicking a solo button to exclusively solo the object for which the solo button is associated.

[Note] Note

Mute and Solo are designed to be used for monitoring purposes only and are not persisted in the project or stored in the SoundBanks.

Relative Properties

Interface Element

Description

Bus Volume

The attenuation (level or amplitude) applied on the audio signal at the bus or Auxiliary Bus level. Refer to Understanding the Voice Pipeline for more information about volumes.

Default value: 0
Range: -200 to 200
Units: dB

[Note] Note

The default slider range is from -96 to +12. You can go over those limits by entering the value directly, or by rolling the mouse while the focus is on the edit control.

Voice Volume

The attenuation (level or amplitude) applied on the current object before it is routed to a bus or sent to an Auxiliary Bus. Refer to Understanding the Voice Pipeline for more information about volumes.

Default value: 0
Range: -400 to 400
Units: dB

[Note] Note

The default slider range is from -96 to +12 dB. You can go over those limits by entering the value directly or by rolling the mouse while the focus is on the edit control.

Voice Pitch

The playback speed of an audio object, where:

  • Pitch 0 = Normal speed.

  • Pitch 1,200 = 2 x speed.

  • Pitch 2,400 = 4 x speed.

  • Pitch 4,800 = 8 x speed.

  • Pitch -1,200 = 0.5 speed

  • Pitch -2,400 = 0.25 speed

  • Pitch -4,800 = 0.125 speed

[Tip] Tip

1,200 cents is equivalent to one octave.

Default value: 0
Range: -4,800 to +4,800
Units: Cents

Voice Low-pass Filter

A recursive filter that attenuates high frequencies based on the value specified.

The units for this filter represent the percentage of low-pass filtering that has been applied, where 0 means no low-pass filtering (signal unaffected) and 100 means maximal attenuation.

Default value: 0
Range: 0 to 100
Units: Percent
(For more detail, see Wwise LPF Value Cutoff Frequencies.)

Voice High-pass Filter

A recursive filter that attenuates low frequencies based on the value specified.

The units for this filter represent the percentage of high-pass filtering that has been applied, where 0 means no high-pass filtering (signal unaffected) and 100 means maximal attenuation.

Default value: 0
Range: 0 to 100
Units: Percent

The High-pass Filter is not available on the Vita Hardware platform.

Bus Specific

Interface Element

Description

(Meter)

A per channel peak meter. For more information about speaker configurations and channels, refer to Understanding Channel Configurations.

The signal level is green under -6 dB, yellow from -6 to 0 dB, and red over 0 dB.

[Note] Note

Meters are only available on mixing busses. To be a mixing bus, a bus must be the master or an Auxiliary Bus, or an Audio Bus with at least one effect enabled, positioning enabled, or not using the "Parent" channel configuration. Refer to Mixing Versus Non-Mixing Busses for more information on this distinction.

 

Channel Configuration

Specifies which channel configuration should be used in this bus. If set to anything other than Parent, it forces a submix at this level of the hierarchy. Parent means that this Bus inherits the channel configuration of its parent. The channel configuration of the Master Audio Bus is implicitly set to Parent, because it inherits the channel configuration of the associated sink/audio output device.

This setting is useful to save CPU for Effects that will be applied on this bus because reducing the number of channels usually reduces the required CPU to process the Effect.

This option works only on software pipeline platforms.

For more information, refer to Understanding Channel Configurations.

 

Mute for Background Music

Enable to specify that the bus will be muted when user music starts. Refer to Replacing Music with a Player's Own Music for important further information.

Game-defined Auxiliary Sends

Interface Element

Description

Use game-defined auxiliary sends

Determines whether the object is using the game-defined auxiliary sends for the game object. A game-defined send is a combination of an Auxiliary Bus and a send volume.

Enable this option to have the object affected by the values coming from the game for the following functions:

Volume (Game-defined auxiliary sends)

Determines the attenuation on the game-defined auxiliary sends volumes set for the game object.

Use this volume to offset game-defined auxiliary send values.

Default value: 0
Range: -200 to 200
Units: dB

[Note] Note

The default slider range is from -96 to +12. You can go over those limits by entering the value directly, or by rolling the mouse while the focus is on the edit control.

User-Defined Auxiliary Sends

Interface Element

Description

Click the Configure Columns... shortcut (right-click) option from the column header band.

The Configure Columns Dialog opens. Specify which columns to display and their order.

ID column (User-Defined Auxiliary Sends)

Determines the ID of the User-Defined Auxiliary Sends. Up to 4 different sends can be added.

Auxiliary Bus column (User-Defined Auxiliary Sends)

Determines the Auxiliary Bus this object is sending audio data to. Auxiliary sends can only target Auxiliary Busses.

To add an auxiliary send:

  1. Click the selector [...] button.

  2. Select an Auxiliary Bus from the Master-Mixer Hierarchy.

  3. Click OK.

  4. Set the send volume for this newly added send.

[Note] Note

Auxiliary Busses can be created anywhere in the Master-Mixer Hierarchy as children of an existing Bus or an existing Auxiliary Bus.

[Tip] Tip

You can drag and drop an Auxiliary Bus object from the Project Explorer to the User-Defined Auxiliary Sends list to quickly add a send.

[...] column (User-Defined Auxiliary Sends)

Allow to select an Auxiliary Bus from the Master-Mixer Hierarchy.

Volume column (User-Defined Auxiliary Sends)

Determine the attenuation of the signal sent to the Auxiliary Bus.

Default value: 0
Range: -200 to 200
Units: dB

[Note] Note

The default slider range is from -96 to +12 dB. You can go over those limits by entering the value directly, or by rolling the mouse while the focus is on the edit control.

[Note] Note

This control is only active when an Auxiliary Bus is selected for a specific send entry.
