• Gain Reduction meter/graph: Click either the Meter or Graph button to change the real-
time compression amount display.
• Input Gain knob and field: Set the level at the compressor input.
• Input Gain meter: Displays the level at the compressor input.
• Threshold knob and field: Set the threshold level—signals above this threshold value are
reduced in level.
• Ratio knob and field: Set the compression ratio—the ratio of signal reduction when the
threshold is exceeded.
• Make Up knob and field: Set the amount of gain applied to the compressed signal.
• AutoGain buttons: The Off button disables autogain. The 0 dB and -12 dB buttons
compensate for volume reductions caused by compression.
• Knee knob and field: Set the strength of compression at levels close to the threshold.
Lower values result in more severe or immediate compression (hard knee). Higher
values result in gentler compression (soft knee).
• Attack knob and field: Set the time it takes for Compressor to react when the signal
exceeds the threshold.
• Release knob and field: Set the time it takes for Compressor to stop reducing the signal
after the signal level falls below the threshold. This parameter works in conjunction with
the Auto Release function when active.
• Auto Release button: Make the release time dynamically adjust to the audio material.
The behavior of the auto release function (and compression results) change when
different Release knob values are used.
• Output Gain knob and field: Set the overall level of the compressor output.
• Output Gain meter: Displays the overall level of the compressor output.

Compressor output parameters are shown to the right when the Output button is active.
