Downward and Upward Expansion.
To summarize:
•Downward compression (common): make loud signals quieter
•Upward compression (uncommon): make quiet signals louder
•Downward expansion (common): make quiet signals quieter
•Upward expansion (uncommon): make loud signals louder
The Multiband Dynamics device allows for all of these types of processing. In fact, because the
device allows for incoming audio to be divided into three frequency bands, and each band has
both an upper and lower threshold, a single instance of Multiband Dynamics can provide six
types of dynamics processing simultaneously.
22.22.2 Interface and Controls
The High and Low buttons toggle the high and low bands on or off. With both bands off, the
device functions as a single-band effect. In this case, only the Mid controls affect the incoming
signal. The frequency sliders below the High and Low buttons adjust the crossovers that define
the frequency ranges for each band. If the low frequency is set to 500 Hz and the high fre-
