UAD Powered Plug-Ins Manual - 431 - Chapter 44: SPL Transient Designer
Figure 136 on page 431 shows the difference between Env 1 and Env 2 that
defines the control voltage of the VCA. The shaded area marks the difference
between Env 1 and Env 2 that controls the control voltage of the VCA. The am-
plitude of the attack is increased if positive ATTACK values are set. Negative
ATTACK values reduce the level of the attack transient.
Figure 137 on page 431 displays the processed waveforms with maximum
and minimal ATTACK to compare against the original waveform in diagram
1.
