Adaptive Limiter in Logic Pro for iPad
Adaptive Limiter is a versatile tool for controlling the perceived loudness of sounds. It works by rounding and smoothing peaks in the signal, producing an effect similar to an analog amplifier being driven hard. Like an amplifier, it can slightly color the sound of the signal. You can use Adaptive Limiter to achieve maximum gain, without introducing unwanted distortion and clipping, which can occur when the signal exceeds 0 dBFS.
Adaptive Limiter is typically used on the final mix, where it can be placed after a compressor, such as Multipressor, and before a final gain control, resulting in a mix of maximum loudness. Adaptive Limiter can produce a louder-sounding mix than can be achieved by normalizing the signal.
To add Adaptive Limiter to your project, choose Dynamics > Adaptive Limiter 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.
Note: Adaptive Limiter adds latency when the Lookahead parameter is active. The effect is most commonly used for mixing and mastering previously recorded tracks, not while recording. You should bypass Adaptive Limiter while recording.
Adaptive Limiter parameters
Input meters: Show input levels in real time. The Margin field shows the peak input level.
Reduction meter: Show the amount of gain reduction. The Margin field shows the peak reduction level.Output meters: Show output levels of the limited signal. The Margin field shows the peak output level.
- Gain knob and field: Set the amount of gain after input scaling.
- Out Ceiling knob and field: Set the maximum output level, or ceiling. The signal does not rise above this.
TP Detection button: Turn on to detect inter-sample peaks (true peaks) in the signal.
Remove DC button: Turn on to activate a highpass filter that removes direct current (DC) from the signal. DC can be introduced by lower-quality audio hardware.
Lookahead knob and field: Set the playback buffer size (how far in the future the file is analyzed for peaks). Also see the Optimal Lookahead parameter. Values lower than the optimal buffer size are indicated in red.
Apply Lookahead button and field: Use the Apply Lookahead button to set the optimal playback buffer size. This changes the value shown in the Lookahead field.
Note: The Optimal Lookahead value is automatically determined and cannot be changed directly.
