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.
Default value: As Input
|
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 4096 Units: Sample frames
|
Delay Dry
|
Determines whether the dry signal should be delayed to preserve synchronization with the harmonized (wet path).
|
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. |
Default value: true
|
Harmonizer Voice Parameters
|
Voice Enable
|
Determines whether a given pitch voice is enabled.
|
Note |
In order to avoid unnecessary artifacts and save resources, 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). |
Default value: false
|
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: -2400 to 2400 Units: cents
|
Voice 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
|
Voice Filter 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.
Default value: None
|
Voice Filter 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.
|
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. |
Default value: 0 Range: -24 to 24 Units: dB
|
Voice Filter Frequency
|
The portion of the frequency spectrum that will be affected by the gain.
Default value: 1000 Range: 20 to 20000 Units: Hz
|
Voice Filter Q Factor
|
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.
This control is not available when the Low Pass, High Pass, Low Shelf, and High Shelf curves have been selected.
Default value: 1 Range: 0.1 to 20
|
Output Levels
|
Dry Level
|
Gain applied to unprocessed signal.
Default value: 0 Range: -96 to 24 Units: dB
|
Wet Level
|
Gain applied to harmonized voices signal.
Default value: 0 Range: -96 to 24 Units: dB
