The Loudness Maximizers
Limiter does not produce
harmonical distortion
Defining the way the Limiter
sounds and defining if invalid
samples are allowed or not.
You can gain more loudness and also start to manipulate sound
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.
The Loudness Maximizer will allow invalid samples possibly resul-
ting in audible distortion. The Possible LED bar will show you
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.
