Ducker/Ducking

A dynamics processor/process that lowers (or “ducks”) the level of one audio signal based upon the level of a second audio signal. A typical application is paging over background music: A ducker senses the presence of audio from a paging microphone and triggers a reduction in the output level of the music signal for the duration of the page signal. It restores the original level once the page message is over. Most dynamics processors (usually compressors are used) that give the user access to the detector circuit can be used for ducking. It is simply a matter of routing a copy/split of the second audio signal (the page in the example above) to the detector input such that it will trigger the gain cell to lower the level of the main signal (the music).
