339 Live Audio Effect Reference
quency is set to 2000 Hz, then the low band goes from 0 Hz to 500 Hz, the mid band from 500
Hz to 2000 Hz and the high band from 2000 Hz up to whatever your soundcard or sample rate
supports.
Each band has activator and solo buttons. With the activator button disabled for a given band,
its compression/expansion and gain controls are bypassed. Soloing a band mutes the others.
The Input knobs boost or attenuate the level of each band before it undergoes dynamics pro-
cessing, while the Output knobs to the right of the display adjust the levels of the bands after
processing.
The display area provides a way of both visualizing your dynamics processing and adjusting the
relevant compression and expansion behavior. For each band, the output level is represented
by large bars, while the input level before processing is represented by small bars. With no pro-
cessing applied, the input meters will be aligned with the top of the output meters. The scaling
along the bottom of the display shows dB. As you adjust the gain or dynamics processing for a
band, you can see how its output changes in comparison to its input.
As you move your mouse over the display, the cursor will change to a bracket as it passes over
the edges of the blocks on the left or right side. These blocks represent the signal levels under the
Below and over the Above thresholds, respectively. Dragging left or right on the edges of these
blocks adjusts the threshold level. Holding down [Shift] while dragging a threshold will adjust
the same threshold for all bands. Hold down [ALT](PC) / [ALT](Mac) to simultaneously adjust the
Above and Below thresholds for a single band.
As you mouse over the middle of the block, the cursor will change to an up-down arrow. Click
and drag up or down to make the signal within the selected volume range louder or quieter.
Holding down [Shift] while dragging up or down will adjust the volume of the same block for all
bands. Hold down [ALT](PC) / [ALT](Mac) to simultaneously adjust the Above and Below vol-
umes for a single band. Double-clicking within the region resets the volume to its default.
In technical terms, lowering the volume in the block above the Above threshold applies down-
ward compression, while raising it applies upward expansion. Likewise, lowering the volume in
the block below the Below threshold applies downward expansion, while raising it applies up-
ward compression. In all cases, you are adjusting the ratio of the compressor or expander.
The thresholds and ratios of all bands can also be adjusted via the column to the right of the
display. The ”T,” ”B” and ”A” buttons at the bottom right of the display area toggle between
displaying the Time (attack and release), Below (threshold and ratio) and Above (threshold and
ratio) for each band.
