2.1 Input Clipping
The Inflator process develops internal signal levels that are notionally greater than
digital maximum. For instance, with the
EFFECT level at maximum and the Clip 0dB
off, signal peaks above notional digital maximum can be accommodated, and much
of their harmonic information can be included in the output signal, even though the
peak output level will not rise above digital maximum. The presence of this extra
signal range is displayed on the upper sections of the
INPUT level meter, and
represents a range of up to +6dBr of useable overdrive before hard clipping occurs.
The
CLIP 0dB
function suppresses this extra range and restricts the Inflator process
to the normal digital maximum range. Therefore, you will note that, with CLIP 0dB
selected, the input level meter will not rise above 0dB, however much input gain is
employed. Because the potential applications of this process are so varied, you are
encouraged to experiment with
CLIP 0dB
on and off, to obtain the best results
depending on your intentions. Here are some general guidelines:
Generally it is better to start by selecting CLIP 0dB on (the default) for most loudness
enhancement purposes including direct mode (non-band split) since the control of
peak levels, settings and sound character is more readily achieved when a maximum
reference level is imposed on signals before the Inflator process.
In certain cases better results may be obtained by de-selecting any input limiting. In
particular, the extra useable range can then be used to accommodate short-term
overshoot sounds produced by compression functions, where they are generated to
enhance attack and presence. Since these peaks are mostly short duration, they can
