311 Live Audio Effect Reference
(Note: the EQ Eight effect is not available in the Intro and Lite Editions.)
The EQ Eight effect is an equalizer featuring up to eight parametric filters per input channel, use-
ful for changing a sound’s timbre.
The input signal can be processed using one of three modes: Stereo, L/R and M/S. Stereo
mode uses a single curve to filter both channels of a stereo input equally. L/R mode provides an
independently adjustable filter curve for the left and right channels of a stereo input; M/S mode
(Mid/Side) provides the same functionality for signals that have been recorded using M/S en-
coding. In all modes, the frequency spectrum of the output is displayed behind the filter curves
when the Analyze switch is on.
When using the L/R and M/S modes, both curves are displayed simultaneously for reference,
although only the active channel is editable. The Edit switch indicates the active channel, and is
used to toggle between the two curves.
Each filter has a chooser that allows you to switch between eight responses. From top to bottom
in the choosers, these are:
•48 or 12 dB/octave Low cut (cuts frequencies below the specified frequency);
•Low shelf (boosts or cuts frequencies lower than the specified frequency);
•Bell curve (boosts or cuts over a range of frequencies);
•Notch (sharply cuts frequencies within a narrow range);
•High shelf (boosts or cuts frequencies higher than the specified frequency);
•12 or 48 dB/octave High cut (cuts frequencies above the specified frequency).
Each filter band can be turned on or off independently with an activator switch below the
chooser. Turn off bands that are not in use to save CPU power. To achieve really drastic filtering
effects, assign the same parameters to two or more filters.
To edit the filter curve, click and drag on the filter dots in the display. Drag-enclose multiple filter
dots to adjust them simultaneously, either with the mouse or with your computer keyboard’s ar-
row keys. Horizontal movement changes the filter frequency, while vertical movement adjusts
the filter band’s gain. To adjust the filter Q (also called resonance or bandwidth), hold down
the [ALT](PC) / [ALT](Mac) modifier while dragging the mouse. Note that the gain cannot be
