Compressor
Attack Menu
Sets the amount of time that must elapse, once the input signal reaches the
Threshold level, before compression will occur. The faster the Attack, the more
rapidly compression is applied to signals above the Threshold.
Three Attack values are available: Slow (50ms), Medium (8ms), and Fast
(400µs).
Compressor
Release Menu
Sets the amount of time it takes for compression to cease once the input signal
drops below the Threshold level. Slower release times can smooth the transi-
tion that occurs when the signal dips below the threshold, especially useful for
material with frequent peaks. However, if you set too large of a Release time,
compression for sections of audio with loud signals may extend to lengthy sec-
tions of audio with lower signals.
Three Release values are available: Slow (500ms), Medium (120ms), and
Fast (40ms).
Compressor
On/Off Button
Enables or disables the Compressor module within Preflex.The Compressor is
engaged when the button indicator is bright red. You can use this switch to
compare the compressor settings to the original signal or bypass the entire
compressor section to reduce UAD DSP load.
