Noise Gate in Logic Pro for iPad
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.
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.
In Ducker mode, the source signal is reduced in level. Ducking is a common technique used in radio and television broadcasting. When the DJ or announcer speaks while music is playing, the music level is automatically reduced. When the announcement has finished, the music is automatically raised to its original volume level.
To add Noise Gate to your project, choose Dynamics > Noise Gate in a channel strip Audio Effect plug-in menu or the Plug-ins area. See Intro to plug-ins. Also see Add, replace, reorder, and remove plug-ins in the Plug-ins area and Work with plug-ins in the Mixer.
Noise Gate parameters
Threshold knob and field: Set the threshold level. Signals that fall below the threshold are reduced in level.Hysteresis knob and field: Set the difference (in decibels) between the threshold values that open and close the gate. This prevents the gate from rapidly opening and closing when the input signal level is close to the threshold level.
Mode buttons: Set the operating mode: Gate or Ducker. See Use Noise Gate.
- Reduction knob and field: Set the amount of signal reduction.
Activity indicators: Show current gate state.
Attack knob and field: Set the time it takes to fully open the gate after the signal exceeds the threshold.
Hold knob and field: Set the time the gate remains open after the signal falls below the threshold.
Release knob and field: Set the time it takes to reach maximum attenuation after the signal falls below the threshold.
Lookahead knob and field: Control how far ahead Noise Gate analyzes the incoming signal, allowing the effect to respond more quickly to peak levels.
Key Filter button: Turn on to enable the sidechain filter, allowing you to adjust the Low Cutoff and High Cutoff parameters.
Monitor button: Turn on to hear the side chain signal, including the effect of the Low Cut and High Cut filters (if enabled).
Low Cutoff knob and field: Set the lower cutoff frequency for the side chain signal.
Note: When no external side chain is selected, the input signal is used as the side chain control signal.
High Cutoff knob and field: Set the upper cutoff frequency for the side chain signal.
Characteristics buttons: Choose a Bandpass or Band Reject filter type.
