Section 5 ATTACK TIMING
In general, very fast attack times will more readily remove extremely fine detail and short-
term events, but will produce greater harmonic disturbance.
Slower attack times will progressively allow finer detail to escape the harsh sound of fast
limiting, and longer term events will tend to assume a more rounded peak profile. Such
settings are usually kinder to the musical programme.
Note:
The only way slower attack settings can be used without a potential need for a
significant reduction of the output level control is when the
ENHANCE control is set at,
or above, 100% or with SAFE MODE selected. These methods will ‘soft clip’
transients, ie. compress their level before the onset of clipping, providing a warmer,
valve-like saturated sound. Alternatively, enable 16-bit or 24-bit dither, which will ‘hard
clip’ over-unity transients, ie. squaring the top/bottom of waveforms and resulting in a
more distorted sound, often found in transistorised circuits.

Enhance
Section
You should be aware that, since the Pre-Process section is a programme gain controller
rather than a simple sample clipper, programme peaks can cause a small increase in
maximum output sample value, even at the fastest attack time settings. If SAFE MODE
isn’t selected, or the ENHANCE fader is not set at, or above, 100% in Normal Mode,
these peaks will appear at the output of the plug-in. Increasing the attack times will
further increase peak overshoots, so if tight level control is required without the enhancer,
it is best to leave the attack at minimum setting.
Since the plug-in has internal level headroom, the output level control can be safely used
to compensate for any artistically intended overshoot without fear of causing internal
signal clipping.
