Adjustable Volume Control

Click here to return to the Volume Controls section.

This block lets you control which slew curve, and which time constant for the slew algorithm, to use.adjustablevolumecontrol.jpg

Choose slew type using the top drop-down control, Linear, Const[ant] dB, and RC-type:

  • Linear: Slews to target using a fixed step size. The ramp ranges from 6.75 to 213.4 ms.
  • Constant dB: Slews to target using the current value to calculate the step size. The resulting curve has a constant rise and decay when measured in dB. The ramp ranges from 6.1 ms to 1.27 s.
  • RC-type: Slews to target using the difference between the target and current values to calculate the step size. This produces a simple RC-type curve for both rising and falling. The ramp ranges from 6.1 ms to 1.27 s.

With the bottom drop-down control, choose a time-constant value between 0 (fastest volume change) and -15 (slowest volume change). The default block comes with the Gain slew algorithm; right-click the block border or title, per usual, to add input/output pins. The slider controls the input(s) / output(s) the same, and the time constant applies to all inputs. The example at above right shows the default block with one algorithm added.
