Free Plugin for Logic Pro – Duck EQ
Duck EQ by HeelAudio is a Ducker that can act on specific frequencies via side chaining for managing tracks with overlapping frequency content. The plug-in can be used for normal ‘broadband’ ducking as well.
To use the Duck EQ as a Ducker, you simply select the track that should trigger the ducking (e.g the kick drum). For other tasks like de-essing, you select ‘none’. The same signal that is being processed will be used for detection.
Duck EQ is currently available as a 32-bit plug-in only, so you’ll need a 32-bit to 64-bit Audio-Units plug-ins adapter like 32Lives.
