Harmonizer Plug-in Properties

The Wwise Harmonizer plug-in contains a series of properties, many of which can be edited in real-time and can be mapped to specific game parameters using RTPCs.

Interface Element

Description

Name

The name of the effect instance.

Effect instances are a group of effect property settings. They can be one of two types: custom instances or ShareSets. Custom instances can be used by only one object, whereas ShareSets can be shared across several objects.

Effect

The type of effect.

Shared by (Used by)

A list of objects that currently subscribe to the selected ShareSet.

This field is called “Used by” when editing a custom instance of the effect.

Returns the effect property settings to their default values.

This option is only available when editing a custom instance of the effect.

Notes

Additional information about the effect.

Effect Settings

Input

This parameter determines which channels will be processed by the harmonizer.

Values:

  • As Input: All input channels are processed (default).

  • Mono/Center: Only the center channel is processed. Mono signals are also processed.

  • Stereo: Only the front left and right speakers are processed.

  • L/R/C: All front speakers are processed, including center when present.

  • L/R/Ls/Rs: The front and rear stereo pairs are processed.

  • L/R/C/Ls/Rs: All full band channels are processed.

  • Left Only: Only the left channel is processed by the harmonizer. This mode is useful to reduce CPU usage when the effect is inserted on busses and it can be assumed that the audio content routed to the effect is mono sounds that do not use positioning or panning. The result of the harmonized left channel is applied to the wet path of both front left and front right channels. The dry paths preserve the original channel content however.

Process LFE

This parameter determines if the LFE channel will be processed by the harmonizer.

Default Value: False

Window Size

Larger window size gives better frequency resolution but more smearing of transients. This parameter is thus a compromise between time resolution and frequency resolution. See section above for a more detailed discussion on how to choose the value for this parameter.

Default Value: 1024
Range: 256 to 4,096
Units: Sample frames

Delay Dry

Determines whether the dry signal should be delayed to preserve synchronization with the harmonized (wet path).

Default Value: True

[Note] Note

This property has no effect when the harmonizer is used in an Auxiliary Bus. In this case, the dry signal is defined by the object sending to the auxiliary bus.

Harmonizer Voice Parameters

Voice Enable

Determines whether a given pitch voice is enabled.

[Note] Note

In order to avoid unnecessary artefacts and save ressources, make sure you disable all voices that you don't need (instead of using a zero pitch or a very low voice level for example).

Pitch Shift

The pitch is raised or lowered by the amount specified by this parameter (in cents). +1200 Cents is thus transposed an octave up and -1200 is an octave down.

Default Value: 0
Range: -2,400 to 2,400
Units: Cents

Gain

The amount of gain applied to a given harmonized voice. Allows to set a balance between different harmonized voices.

Default Value: 0
Range: -96 to 24
Units: dB

Voice Filter Parameters

Type

Determines the type of filtering that can be applied to the harmonized voice signal. The following filters are available:

  • None to disable the voice filter.

  • Low Pass to provide a fixed sloped attenuation of high frequencies from a specified frequency. Below this point the signal is almost unaffected but higher frequencies are progressively more attenuated past the cutoff frequency point.

  • High Pass to provide a fixed slope attenuation of low frequencies from a specified frequency. Above this point the signal is almost unaffected while lower frequencies are progressively more attenuated below the cutoff frequency point.

  • Band Pass to reject all frequencies around the specified center frequency. The range of frequencies around the center is controlled by the Q.

  • Notch to provide a fixed attenuation of a specified frequency range with a varying width. The range of frequencies around the center is controlled by the Q.

  • Low Shelf to provide gain/attenuation for a specified range of low frequencies. This curve type is also known as Bass Tone Control.

  • High Shelf to provide gain /attenuation for a specified range of high frequencies. This curve type is also known as Treble Tone Control.

  • Peaking to provide amplification/attenuation of a specified frequency range with a varying width. The range of frequencies around the peak is controlled by the Q.

Gain

The amount of the amplification of the harmonized voice signal for the selected frequency band. Increasing this value “boosts” the audio signal. Decreasing this value “cuts” or attenuates the audio signal.

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

[Note] Note

The Gain controls are not available when the Low Pass, High Pass, Notch, and Band Pass curves have been selected because these filter types have their passband normalized at 0 dB.

Frequency

The portion of the frequency spectrum that will be affected by the gain.

Range: 20 to 20,000
Units: Hz

Q

The area around the center frequency that will be affected by the change in gain. A low Q value means that the bandwidth range will be wide, and conversely a high Q value means that the bandwidth range will be narrow.

Default value: 1.0
Range: 0.1 to 20

This control is not available when the Low Pass, High Pass, Low Shelf, and High Shelf curves have been selected.

Output Levels

Dry level

Gain applied to unprocessed signal.

Default value: 0
Range: -96 to 24
Units: dB

[Note] Note

This property has no effect when the harmonizer is used in an Auxiliary Bus. In this case, the dry signal is defined by the object sending to the auxiliary bus.

Wet level

Gain applied to harmonized voices signal.

Default value: 0
Range: -96 to 24
Units: dB
