You can gain more loudness and also start to manipulate sound 2 Desired Gain when you choose other than the initial settings for SOFT-HARD

(see 3) or MORE DENSITY (see 4). After having changed these parameters a readjustment of the DESIRED GAIN is mostly advis- able.

The SOFT-HARD encoder controls the operation of the Limiter

and influences the sound of the Loudness Maximizer. The control

 

 

range is -9 (very soft) to +9 (very hard). The adjusted value is

 

 

shown in the LC-display (details see 6).

 

 

The higher the adjusted value the harder the sound becomes.

increasing values (more subjective loudness to gain) the more

 

 

the SOFT-HARD control is turned to hard. Use the DESIRED GAIN

 

 

control to exploit the additional loudness.

 

 

Low SOFT-HARD values (i.e. -9 up to -5) let the Limiter recalcu-

 

 

late the original curve on a lower level allowing no invalid

 

 

samples at all. This way of operation is very unobstrusive but will

 

 

not allow very high loudness maximizations.

 

 

The setting of the SOFT-HARD control is an aesthetical question

 

 

and extremely dependent on taste and the source material.

 

 

Roughness, sharpness and distortion become audible when

 

 

critical program material like classical music or single instruments

 

 

that show almost sine-wave like waveforms are treated with Hard

 

 

settings. In these cases set the SOFT-HARD control between -9

 

 

and -3.

 

 

Music with a high density in high frequencies or complex

 

 

signals can be treated with values between -6 and +3 without

 

 

creating audible distortion. Uncritical material like dance floor

 

 

productions, jingles or promos may be treated with values

 

 

between 0 and +9.

 

 

In comparison to other systems with soft and hard limiting the

 

 

Loudness Maximizer does not produce additional harmonics.This

 

 

phenomenon is a standard problem with other systems leading

 

 

to increased sharpness and sound manipulation.
