Pre-Anticipation (Lookahead delay) control
This parameter changes the integration time for RMS detection and thus changes the effect of the DRC
circuit.
The delay setting here also determines the delay that will be applied to signals passing through the
plug-in NOT not be selected for processing when Delay Compensation is switched ON
Note: Please note that this parameter delays the all signals running through the Bus
Tools plug-in, so phase or other timing errors may occur when the plug-in is used in
places other than the mix bus.
EQ and Output Sections
These are identical to the Strip Tools versions.
It is worth noting that, since the Limiter is in this case a brickwall design, the Automatic Gain Make-up
function compensates for the same amount as the value set by the Threshold Control of the Limiter.
The resulting signal will be close to, but never exceed OdBFS. If Gain Make-up is Off the Output Level
Control will act as a ‘ceiling’ control, setting the absolute level of the resulting output signal.
Delay Compensation / Pre-Anticipation
Example
In this table Bus Tools Instance 1 is IN circuit for the Left and Right channels of the mix and Bus Tools
Instance 2 is IN circuit for the Left Surround and Right Surround channels. For the Center and Sub-
Woofer Channels both Bus Tools are OUT of circuit. BUT Pre-Anticipation and Delay Compensation is
switched ON for the channels selected for processing. To ensure proper time alignment all channels are
automatically delayed by the same total amount. (the 8.71 and 5.8 figures are arbitrary)
If all channels are selected for processing (in circuit) with linked Pre-Anticipation then there is no need
to activate Delay Compensation.
