83Logic Pro Effects
• Soft: Rounds off the signal as it approaches the 0 dB level, reducing the overall
signal, rather than abruptly cutting it off.
• Hard Emulates a transistor effect that abruptly cuts off signals above 0 dB.
• Clip: Cuts off the signal at the 0 dB mark, but can be more punchy than the Hard
setting, depending on the input material.
• Mix knob and field: Set the balance between dry (source) and wet (effect) signals.
This enables you to either reduce signal peaks (dry), or to increase the level of
softer signals (wet).
Logic Pro Compressor side chain parameters
Compressor side chain parameters are shown to the right when the Side Chain button
is active.
Note: Not all parameters listed are available in each Compressor model.
Compressor sidechain parameters
• Detection buttons: Choose the way stereo sidechain signals are handled at the
sidechain input.
• Max button: Turn on to compress both channels if either stereo channel exceeds or
falls below the threshold.
• Sum button: When enabled, the combined level of both channels must exceed the
threshold before compression occurs.
• Peak/RMS buttons: Use in conjunction with the Max and Sum buttons. Choose Peak
or RMS to determine whether signal peaks or a signal average is used for detection.
These can help with avoiding artifacts such as clicks in the processed signal,
depending on the type of audio material and parameter settings (notably Attack).
• Filter buttons: Turn the filter on or off. Turn on Listen to monitor the sidechain signal.
