• Make Up knob and field: Set the amount of gain applied to the compressed signal.
• Auto Gain buttons: The Off button disables autogain. The 0 dB and -12 dB buttons
compensate for volume reductions caused by compression.
• Knee knob and field: Set the strength of compression at levels close to the threshold.
Lower values result in more severe or immediate compression (hard knee). Higher
values result in gentler compression (soft knee).
• Attack knob and field: Set the time it takes for Compressor to react when the signal
exceeds the threshold.
• Release knob and field: Set the time it takes for Compressor to stop reducing the signal
after the signal level falls below the threshold. This parameter works in conjunction with
the Auto Release function when active.
• Auto Release button: Make the release time dynamically adjust to the audio material.
The behavior of the auto release function (and compression results) change when
different Release knob values are used.
• Output Gain knob and field: Set the overall level of the compressor output.
• Output Gain meter: Displays the overall level of the compressor output.
Logic Pro Compressor output parameters
Compressor output parameters are shown to the right when the Output button is active.
Compressor output parameters
• Limiter button: Turn the integrated limiter on or off. Limiting prevents the output of
Compressor from exceeding the threshold value.
• Limiter Threshold knob and field: Set the threshold level for the limiter.
• Distortion knob: Choose whether to apply clipping above 0 dB, and the type of clipping.
Soft, Hard, and Clip reduce the signal around the 0 dB line in different ways, resulting in
a smoothed or squared off distortion of the signal peaks. Experiment with these options
