Dynamic mixing is common in video games. Real-time parameter controls, mix events, and mixer snapshots are frequently used to control audio focus. Another powerful tool for achieving clarity in games is side-chaining.
Side-chaining consists of monitoring the level of an audio signal and using it to manipulate another audio signal. A concrete example of side-chaining occurs in radio broadcasting where a DJ's voice automatically ducks the music volume. In music production, side-chaining is often used to control the energy in the low end of the frequency spectrum when the bass drum quickly ducks the bass volume.
