Fig. 5 shows the control behavior using a sinus burst as an example. In various
settings it is clearly to see that the burst signal remains almost unchanged in
its form; only the intensity changes.
The PTC feature can provide outstanding results not only for percussive
signals but also for many other musical signals (vocals, guitar, bass, horns,
synthesizers, etc.), since compression is used with the greatest efficiency, is
unobtrusive and sounds „natural“. You should feel free to jump right in to
experimenting with the PTC and find out what it can do for you.
The Release control
The Release control is used to determine how long the compressor needs
after a reduction to drop back to the original value. How it works is shown in
Fig. 6.
Here you see the same sinus burst as for the attack diagrams, but just the
last burst-on part is shown. You can clearly see how the times within which
the original is reached change with various settings of the release control.
