Free Dead Duck Software, Expander Download

As the name might suggest the Expander is basically an 'inverted' compressor in that is allows dynamic range to be increased by applying gain reduction to the signal when it falls below a set threshold. These basic differences aside the controls of the Expander are much the same as those of the Compressor: set the 'Threshold' to determine when gain reduction is applied and 'Ratio' to determine by how much.

Although it is similar in operation to the Compressor, the signal flow of the Expander is closer to that of the Gate since it lacks the Makeup and Mix controls of the compressor:

In fact it can be useful to think of the Expander as a Gate, in which the signal below the threshold is reduced rather than blocked.

As with the Compressor and Gate the signal used to determine the gain reduction can be trimmed, filtered and monitored using the controls in the 'Sidechain' section. Activate the 'External' switch to use an external signal (from inputs 3 & 4) to control the expansion.
