• Out Ceiling knob and field: Sets the maximum output level, or ceiling. The signal will<br />
not rise above this.<br />
• Output meters (to the right): Show output levels, allowing you to see the results of the<br />
limiting process. The Margin field shows the highest output level. You can reset the<br />
Margin field by clicking it.<br />
Compressor<br />
The Compressor is designed to emulate the sound and response of a professional-level<br />
analog (hardware) compressor. It tight<strong>en</strong>s up your audio by reducing sounds that exceed<br />
a certain threshold level, smoothing out the dynamics and increasing the overall<br />
volume—the perceived loudness. Compression helps bring the key parts of a track or<br />
mix into focus, while prev<strong>en</strong>ting softer parts from becoming inaudible. It is probably the<br />
most versatile and widely used sound-shaping tool in mixing, next to EQ.<br />
You can use the Compressor with individual tracks, including vocal, instrum<strong>en</strong>tal, and<br />
effects tracks, as well as on the overall mix. Usually you insert the Compressor directly<br />
into a channel strip.<br />
Compressor Parameters<br />
The Compressor offers the following parameters:<br />
• Circuit Type pop-up m<strong>en</strong>u: Choose the type of circuit emulated by the Compressor. The<br />
choices are Platinum, Class(ic) A_R, Class(ic) A_U, VCA, FET, and Opto (optical).<br />
• Gain Reduction meter: Shows the amount of compression in real time.<br />
• Attack knob and field: Determines the amount of time it takes for the compressor to<br />
react wh<strong>en</strong> the signal exceeds the threshold.<br />
