More Density

With the MORE DENSITY control you can change the principle

 

 

behaviour of the control loop of the Loudness Maximizer. This

 

 

parameter describes the Compressor-to-Limiter proportion. In

 

 

addition, internal rules and algorithms will be changed, too. The

 

 

higher the MORE DENSITY setting is the more “work” will be done

 

 

by the Compressor. If MORE DENSITY is set to 0 only the Limiter is

adjusted value is displayed in the LC-display (see 6).

Adjustment: The MORE DENSITY control should be adjusted carefully for mastering tasks. Since there is always a need for a compromise between limiting and compression there can be no optimum adjustment. 0 to 10 are good starting values. When the MORE DENSITY control is set to 24 the Loudness Maximizer tries to gain loudness only by compression. In this case the overall level starts to decrease as the compressor pulls high levels down and lifts up low-level parts of the signal.

Advice: If you want to compress audio heavily here is a tip on how to maintain maximum output level:

Example: DESIRED GAIN 8 dB, More Density12. This MORE

DENSITY setting reduces maximum output level by ca. 2-3 dB.

To compensate for the level difference make these adjustments: DESIRED GAIN 11 dB, MORE DENSITY 8. Result: The compression remains the same and the maximum output level is maintained.

Boost5 The BOOST button (some call it the “client button”) gives the definite kick to the signal. It increases the loudness by another 2dB, regardless of any other adjustments.

Using the BOOST button is very much depending on the program material. Using it with Trance/Techno, or jingles etc. is uncritical. Some Pop/Rock productions might benefit as well. It is definitely a nice tool to create very impressive samples.

In the tradition of impressing clients who just want more and more this button does the job well.

LC-Display6 The LC-display shows all encoder settings and the number of the preset being used in the last session with the Loudness Maximizer (for details on Presets refer to 8).
