Limiter in Logic Pro for iPad
Limiter works much like a compressor but with one important difference: where a compressor proportionally reduces the signal when it exceeds the threshold, a limiter reduces any peak above the threshold to the threshold level, effectively limiting the signal to this level.
Limiter is used primarily when mastering. Typically, you apply Limiter as the very last process in the mastering signal chain, where it raises the overall volume of the signal so that it reaches, but does not exceed, 0 dB.
To add Limiter to your project, choose Dynamics > 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.
Limiter is designed in such a way that if set to 0 dB Gain and 0 dB Output Level, it has no effect on a normalized signal. If the signal clips, Limiter reduces the level before clipping can occur. Limiter cannot, however, fix audio that is clipped during recording.
Limiter parameters
Input meters: Show input levels in real time. The Margin field shows the highest input level. Tap the Margin field to reset it.
Reduction meter: Shows the amount of limiting in real time.Output meters: Show output levels of the limited signal. The Margin field shows the highest output level. Tap the Margin field to reset it.
- Gain knob and field: Set the amount of gain applied to the input signal.
- Release knob and field: Set the time it takes for Limiter to stop processing, after the signal falls below the threshold level.
Output Level slider and field: Set the output level of the signal.
Lookahead knob and field: Adjust how far ahead (in milliseconds) Limiter analyzes the audio signal. This enables it to react earlier to peak volumes by adjusting the amount of reduction.
Note: Lookahead causes latency, but this has no perceptible effect when you use Limiter as a mastering effect on prerecorded material. Set it to higher values if you want the limiting effect to occur before the maximum level is reached, thus creating a smoother transition.
Limiter Mode pop-up menu: Choose between Legacy and Precision algorithms. Use Precision for hard limiting, but be aware that this can introduce distortion artifacts.
When Legacy mode is active the signal is limited only when it reaches the threshold. The transition to full limiting is nonlinear, producing a softer, less abrupt effect, and reducing distortion artifacts that can be produced by hard limiting (in Precision mode).
TP button (Precision mode): Turn on to detect inter-sample peaks (true peaks) in the signal.
