Multiband Expander is a plug-in that allows you to manage, suppress and control noise in your tracks in a frequency-sensitive way. The 3-band phase-coherent crossover network directs the audio to three independent expanders that you configure to smoothly suppress noise below the threshold you specify. The expanders can also be configured to change the feel of rhythmic patterns by suppressing elements that are played more softly – all in a frequency-sensitive way.
Multiband Expander features SpectraFoo spectral analysis to allow you to zero-in on crossover points and thresholds quickly and with confidence.
The Multiband feature of the expander is extremely useful for controlling noise and hum in guitar tracks, as you can attack the noise more aggressively than the desired signal.
While Multiband Expander is not an essential tool for every mix, when you need it, it will really save the day.
