Kilohearts

A compressor will even out the audio volume by lowering the volume when the signal is loud. This helps shape the dynamics of the sound both at the initial attack and the sustain tail. Each compressor has their own flavour, and the Kilohearts Compressor tastes sweet.

Attack knob - The attack time is the time it takes to lower the volume when the input volume is over the threshold.
Release knob - The release time is the time it takes to return the volume to normal when the input volume is under the threshold.
Mode - In RMS mode the compressor will measure the volume using the root mean square method, which gives an accurate measurement of audio power. In peak mode the compressor will follow the peaks in the audio waveform, which makes it more responsive to transients.
Ratio knob - The ratio decides how much the compressor will reduce the audio volume. At 1:2, for example, the volume will be lowered until it is halfway between the input volume and the threshold.
Threshold knob - The threshold for when the compressor will start lowering the volume.
Makeup knob - The makeup gain will increase the volume of the output signal to compensate for the loss in overall volume that the compressor causes.
VU Meter - Displays the current input level, the selected threshold, and the compressor's current attenuation.
