Strip and Bus Tools : Delay Compensation / Pre-Anticipation
Pre-Anticipation (Lookahead delay) control
This parameter changes the integration time for RMS detection and thus changes the effect of the DRC cir-
cuit.
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 func-
tion 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 0dBfs. 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 automati-
cally 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.
