Audio compression reduces the dynamic range of a signal.
Compression is used at all stages of the music production.
It can either be used as a creative and colorating effect, or as a mixing and mastering tool to shape, refine and beef up your mix.
Depending on the technology used in their circuitry, each compressor design has its own specifications and character, making them convenient for particular uses, and bringing very interesting coloration to the sound.
This can make the use of compressors situational and dependant on the producer or engineer's taste.
Here is a quick tour of the Comp FET-76 main panel parameters.
The FET-76 threshold cannot be adjusted.
To increase the compression, you need to raise the Input.
The louder the audio, the more the gain is reduced.
After the compression starts reducing the signal amplitude, you usually need to compensate for the volume loss. To do that, raise the output gain.
When raising the Input knob, the Link control will make the Output knob to move the opposite side.
This acts as a kind of gain compensation, but we would recommend only using it as a guide.
The amount of time required for compression to fully operate once the input signal goes above the threshold level.
The amount of time required for compression to fully stop operating after the input signal goes below the threshold level.
Sets how much the compression affects the sound.
The higher the ratio is, the more the signal will be compressed.
Blends the Dry and Wet signal.
This is a convenient way to easily achieve "New York" / Parallel compression.
Lets you choose if the compressor input signal (internal), or another track (external) triggers the compression.
Just like the input knob, this control lets you raise the side-chain gain to increase the compression level.
Determines if the compression trigger and effect is mono or stereo.
Lets you filter the side chain signal.
Mostly used to take off lower frequencies and avoid, or hone in one, the pumping effect caused by kicks or basses.
In case you only trust your ears, this let's you hear the side chain signal and the equalization applied on it.
Prevents the compression exceeding a certain amount in dB by restraining the compression range.
If you want to copy the settings on A to B or vice-versa, select the snapshot you want to copy from (the source) and click over the arrow.
This will make the settings of that snapshot be copied over to the other snapshot.
Note: The arrow is always pointing from the currently selected snapshot (Source) to the other one (Destination).
