Geonik's Gate

by George Nicolaidis

Description

The Gate, also known as Expander, increases the dynamic range of a signal such that low level signals are attenuated while the louder portions are neither attenuated or amplified. This behavior is opposite to that of the compressor.

Threshold | The input level after which the signal is attenuated
Compression Ratio | The amount of expansion that is applied. This is telling you that while the input is below the threshold, a change in the input level produces a change in the output that is two times, four times, etc, as large. So with a 4:1 expansion ratio (with the input level below the threshold), a dip of 3 dB in the input will produce a drop of 12 dB in the output. When an expander is used with extreme settings where the input/output characteristic becomes almost vertical below the threshold (say, and expansion ratio larger than 10:1), it is often called a noise gate.
Attack Time | The amount of time the expander takes to respond when the input level rises above the threshold
Release Time | The time taken for the expander to reduce its gain after the input drops below the threshold

Notes

Should work fine. Enjoy, and drop a mail if you have comments / bug reports
