Pitch Shift Plug-Ins : X-Form : X-Form Displays and Controls Overview : X-Form Transient Section Controls

X-Form Transient Section Controls
The Transient section provides controls for setting the sensitivity for transient detection and for adjusting the analysis window size.
 
Sensitivity
Controls how X-Form determines and interprets transients from the original audio. Part of X-Form’s processing relies upon separating “transient” parts of the sample from “non-transient” parts. Transient material tends to change its content quickly in time, as opposed to parts of the sound which are more sustained. Sensitivity is only available when Polyphonic is selected as the Audio Type.
For highly percussive material, lower the Sensitivity for better transient detection, especially with the Rhythmic audio setting. For less percussive material, a higher setting can yield better results. Experiment with this control, especially when shifting drums and percussive tracks, to achieve the best results.
Window
Sets the analysis window size. You can adjust the Window from 10.0 milliseconds to 100.0 milliseconds. Adjust the Window control or click the Window field and type the desired value. Window is only available when Monophonic is selected as the Audio Type.
Try larger window sizes for low frequency sounds or sounds that do not have many transients. Try smaller window sizes for tuned drums and percussion. However, the default of 25 milliseconds should work well for most material.
