Matthieu Brucher has released ATKTransientSplitter, a mono transient splitter based on the Audio Toolkit.
- RMS is the size of the power windows.
- Attack is the attack time constant for the slow attack/release filter.
- Attack fraction (or ratio) is the percentage of the attack time constant that will be used for the fast attack/release filter. Used to work on the transient at the beginning of a sound.
- Release is the release time constraint for the fast attack/release filter (as the release time has to be higher).
- Release fraction (or ratio) is the percentage of the release time constant that will be used for the slow attack/release filter (as it has a faster release time constant). Used to work on the transient at the end of sound.
- Slope is the ratio, 1 keeping the sustain at a constant RMS above the threshold, higher means that the sustain will be reduced by this factor (swell-like behavior).
- Softness is an indicator of the harshness of the knee of the underlying swell.
The plugin is a free download for Windows and Mac (VST/AU).
