The nvelope is a powerful audio processor capable of making subtle or drastic changes to a sound by providing control over its attack and sustain characteristics. This is extremely useful for reshaping all sorts of individual tones, and is a wonderful tool in any mixing situation as well.
The nvelope operates independently of the specific level of a signal, and (unlike with compressors) you do not have to spend a lot of time trying to balance a set of complex controls to quickly get the results you seek.
Full Range mode is especially fast and easy to use, as all you need to do is dial in more or less attack and sustain by turning their specific controllers to the left (reduction) or to the right (increase).
Similar to a compressor and unlike in Dual Band mode, you can use the Freq A controller to reduce the influence of low frequencies on the attack processing (higher frequency = less bass influence).
