[. . . ] Set Lookahead to higher values when the Peak/RMS fields are set to higher values (farther towards RMS). Set Auto Gain to On to reference the overall processing to 0 dB, making the output louder. Noise Gate The Noise Gate is commonly used to suppress unwanted noise that is audible when the audio signal is at a low level. You can use it to remove background noise, crosstalk from other signal sources, and low-level hum, among other uses. The Noise Gate works by allowing signals above the threshold level to pass unimpeded, while reducing signals below the threshold level. This effectively removes lower-level parts of the signal, while allowing the desired parts of the audio to pass. 78 Chapter 4 Levels Effects Noise Gate Parameters The Noise Gate has the following parameters. • Threshold slider and field: Sets the threshold level. Signals that fall below the threshold will be reduced in level. • Reduction slider and field: Sets the amount of signal reduction. • Attack knob and field: Sets the amount of time it takes to fully open the gate after the signal exceeds the threshold. • Hold knob and field: Sets the amount of time the gate is kept open after the signal falls below the threshold. • Release knob and field: Sets the amount of time it takes to reach maximum attenuation after the signal falls below the threshold. • Hysteresis slider and field: Sets the difference (in decibels) between the threshold values that open and close the gate. To remedy this, use the side-chain controls to isolate the desired trigger signal with the High Cut and Low Cut filters. Important: The side-chain signal is used only as a detector/trigger in this situation. The filters are used to isolate particular trigger signals in the side-chain source, but they have no influence on the actual gated signal—the audio being routed through the Noise Gate. To use the side-chain filters 1 Click the Monitor button to hear how the High Cut and Low Cut filters will affect the incoming trigger signal. 2 Drag the High Cut slider to set the upper frequency. Trigger signals above this are filtered. 3 Drag the Low Cut slider to set the lower frequency. Trigger signals below this are filtered. 80 Chapter 4 Levels Effects The filters allow only very high (loud) signal peaks to pass. In the drum kit example, you could remove the hi-hat signal, which is higher in frequency, with the High Cut filter and allow the snare signal to pass. Turn monitoring off to set a suitable Threshold level more easily. Spectral Gate The Spectral Gate is an unusual filter effect that can be used as a tool for creative sound design. It works by dividing the incoming signal into two frequency ranges—above and below a central frequency band that you specify with the Center Freq and Bandwidth parameters. [. . . ] • Glide slider and field (Extended Parameters area): Determines the amount of time the vocal transformation takes, allowing sliding transitions to the set Pitch value. • Grain Size slider and field (Extended Parameters area): The Vocal Transformer effect algorithm is based on granular synthesis. The Grain Size parameter allows you to set the size of the grains, and thus affect the precision of the process. • Formants pop-up menu (Extended Parameters area): Determines whether the Vocal Transformer processes all formants (“Process always” setting), or only the voiced ones (“Keep Unvoiced Formants” setting).
